Have you got to know your nails before buying a nailing tool?

Tag: nailing tool, carbide inserts, carbide tools

When you enter the nail industry, you will find that there are too many types of nails. If you don't know enough about your nails, how do you know what type of nail tools to buy? UKO engaged in nail industry for many years, do all kinds of nail tools, has been widely praised. Sometimes few customers have problems about the nail gripper dies, and they have a common drawback that they are not know about their nails.

We usually use a lot of steel nails, but steel nails this variety is divided into many varieties. The main varieties are round nail, flat head nail, flat head nail, square nail, triangle nail, riding nail, twist nail, nail, cement nail, put together nail, felt nail, corrugated nail and so on. The most widely used is the ordinary round nail.

Although there are many types of nails, there are only three things you need to know when choosing a nail tool:

The type of nail head decides the shape of the punch you choose. For example, the smooth head and chequered head pictured above show a distinct difference between smooth head and chequered head. In this way, the obvious difference determines which punch you should choose.

2.The wire size&Whether need chamfer on the head of the nails
  The wire size not only decides the size of the carbide inserts of the nail mold, but also the bore size of the carbide inserts. Whether chamfer is needed for the nail cap determines whether chamfer is needed for the nail die.

3.The Angle of the nail tip is required
The type of nail tip determines the Angle of the nail knife you choose. If you have a sharp nail tip, you need to tell your supplier to sharpen the edge of your nail knife so that you can produce a sharp nail tip. Of course, here I also want to tell you a tip, in case you buy a nail knife is not sharp enough, you can use the grinding wheel to sharpen the nail knife.

There are many kinds of nails. When you don't know how to make an inquiry with a supplier, you only need to make an inquiry with the supplier according to the above three aspects. Then the supplier will know that you are a professional buyer, and the price quoted to you is also very professional, because some suppliers will bully non-professional buyers and offer high prices to customers. As a professional supplier of hard alloy nail tools, UKO is always providing the most suitable solutions to our customers. I hope my article can help you, you can contact me if you have any questions about carbide tools.

Pick the right tool for making nail

Tag: nail knife, nail making machine

I believe that many people in the nail industry must have encountered this situation when working, During the nail-making operation, the nail tip suddenly cracked, resulting in the production can not be carried out normally. Why is it that the nailing machine is purchased at a high price, but it is not handy?

In fact, this problem is very common. Don't panic too much about not being able to deliver the product to the customer within the delivery date. Procurement colleagues should not doubt whether their professional judgment has gone wrong. As long as you continue to read this article, you can find the problem in half an hour!

First of all, there are two major causes, one is the cause of the nail knife, the other is the cause of the nail wire.

In this case, we should stop the machine first, and then observe the nail knife to see if the nail knife is damaged, clips (the nail knife is not sharp enough, cutting constantly, leading to the nail silk lotus root broken wire connection), the center of the non-alignment (poor concentricity) and other issues; If everything is normal, it is necessary to replace the nails and temper the replaced nails again, so that the problem can be solved. Therefore, good production materials can not only determine the quality of products, but also ensure the service life of the die.

Secondly, a common case is that the nails and caps are skewed.
If such a problem is encountered, it should be checked whether the center of the two nail knives of the nail making machine is consistent with the center of the nail mould, and whether the front and back of the nail knife are regular. In addition, it is necessary to check whether the sinking holes of the two nail moulds of the nailing machine are located on the same plane and whether the shell of the nail moulds is loose. Only one-to-one correspondence can ensure the birth of high-quality nails!

Moreover, the main reason is that the thickness of nails and caps is not up to the standard.
In order to solve this problem, it is also necessary to check the clamps, mainly to check whether the two sets of clamps are the same in height, and also to confirm that the nail-making mechanical clamps can clamp the nail wire. If you want to bring a crown, you must bear its weight; if you want to be a perfect nail, you can't do it without high enough pressure resistance. That's why the so-called Phoenix Bath Fire Nirvana is reborn!

Finally, pay attention to check whether the sinking hole of the fixture has serious wear on one side. No matter how good the production machinery is, it should be cleaned up in time and maintained regularly.

Every product has its specific use, Nails are a common but indispensable part in life. According to the use of various industries, nails can be divided into many kinds. Common are nails (ordinary steel nails); floor nails for wood floor decoration; steel row nails for decoration and furniture manufacturing; clamps for car seats, wire mesh, etc. Since nails are so widely used, manufacturers will attach great importance to the machines they make. What is the working principle of a nail machine? Is it efficient? Is it convenient to operate? These problems directly affect the performance, price, cost and profit of nail machine.

If your partner is still struggling to find the right nail machine supplier, congratulations on seeing this!

Conscientious science popularization,nail making industry new purchasing must see

Tag: Corrugated nail, galvanizing machine, corrugated nail cap slice machine, automatic corrugated nail machine, nail dies

I believe that many young people who have just entered the nail making  industry must have such doubts：
1. What machine should corrugated nails be made of?
2. What raw materials should be selected to make nails?
3. How to deal with the problems encountered in nailing process?
4. Type and use of nails?
5. The working principle of nailing machine?
6. What causes the tool damage of nailing machine to be fast?
7. How to deal with the quality problems of nails produced?

Today, let's solve the first problem. What kind of machine is the most suitable for making corrugated nails?

First of all, we need to know what corrugated nails are!
In our practical use, corrugated nails are mainly used to connect wood components, as well as to fix asbestos tile and plastic tile. Corrugated nails can be divided into straight rod corrugated nails and flax rod corrugated nails. Compared with ordinary round nails, corrugated nails have umbrella caps, flax rods and zinc-plated surface.

So what machines are needed to produce corrugated nails?
The machines needed for making corrugated nails are galvanizing machine, corrugated nail cap slice machine and automatic corrugated nail machine.The galvanizing machine is mainly used for galvanizing corrugated nails. Its main drum loading is 50-100 kg, and the time control range is 120 per minute.

The corrugated nail cap slicer mainly deals with the nail caps of corrugated nails. The production efficiency of the nail caps is 6*65 per minute.

The automatic corrugated nail machine is the manufacturing and forming process of the whole corrugated nail. The design output of the corrugated nail machine is 110-150 per minute, the power of the motor is 4.2 kw, and the minimum length of the nail is 50 mm and 100 mm. This kind of redesigned release frame of the nail machine can ensure the flexible and balanced rotation of the turntable.

     
The proverb says that if a worker wants to do his job well, he must first use his own tools well, so he can produce a perfect corrugated nail, without the cooperation of galvanizing machine, corrugated nail cap machine and automatic corrugated nail machine.

UKO, as a professional cemented carbide material supplier in China, has been focusing on nailing industry for ten years and has a complete nailing die system. In order to ensure the completion of each nail birth, all UKO staff have been working hard and to escort your production!

Do you know the reason why nail cutters has short service life?

Tag: nail cutter, nail making tools, nail making machine

As the saying goes, if you want to do a good job, you must first sharpen your tools. In the process of making nails, the use of nail cutters is very important. However, many nail manufacturers complain that the nail cutters which they bought is not durable, the service life is very short that they have to replace it frequently, the reasons must be the nail cutter manufacturers are not professional or cheating on workmanship and materials, it may be the truth. Are there any other reasons? Let's analyze the reasons one by one.

There are four other common reasons why nail cutters for nail making machine break down quickly.

1.The hardness for raw materials of nails is too high.
Nail-making raw materials are common steel wire coil on the construction site. There are many specifications of the steel wire coil, we generally choose Q195, Q215 or Q235, their hardness is gradually increasing. If we use Q235 wire coil as the material of nails, the loss for nail cutters is certainly greater than Q195. And the harder material for wire coil we choose, the shorter the working life of the nail cutter will be. Therefore, in order to better cut the nail point we should choose the appropriate grade for nail cutter. UKO use YG20C as the grade of nail cutter, which hardness is up to 82HRA, it is suitable for the production of most nails.

2.The cutting edge of nail cutters is improper.
Some cutting edge does not meet the requirements, which should be noticed that different hardness and strength of the material is applicable to the different cutting edge. For example, for high carbon steel nails with high hardness and abrasion resistance, UKO will be equipped with appropriate grooves to meet the needs of customers. This is also a valuable experience learned from a Thailand customer. After using our nail cutters, the customer finally changed the situation of changing the nail cutters frequently and greatly improved the use time of the nail cutter, so we have cooperated till now.


3.Machine adjustment does not reach the designated position.
The clamping force is insufficient or too tight when the feeding knife or the feeding roller enters the wire. At this time, we should adjust the wire feeder to ensure reliable wire feeding and replace the worn parts of the wire feeder. After the nailing machine starts, it should wait for the machine to work properly before pulling the feed handle into the wire to make nails. When the machine stops, it should stop the feed first. The nail cutters should be kept sharp at any time. We should pay attention to the temperature change and abnormal noise of the friction parts at any time during the nail making machine operation.

4. The adjustment of nail cutters is too tight
When adjusting the nail cutter, we should not adjust the gap of the nail cutter too tightly, nor too wide, otherwise the nail point will be bent or not sharp. In addition, it will increase the loss of the nail cutter. If the distance between the two nail cutters is appropriate, even if there is a small flying edge on the nail point, it can be removed with a single stroke of the hand. At this time, a beautiful nail point can be polished after polishing, and the loss of the nail cutters will be greatly reduced.

Having known the above reasons, I hope you can think about the reasons and whether there are other possibilities when changing nail cutters frequently. Meanwhile, please feel free to contact with us. As a professional nail making tool manufacturer, we are happy to analyze the reason, solve the problem, and provide the most suitable nails making solutions to you.

The top crack is not correct, the nail cap is not round, UKO teaches you to easily get a small trick

Tag: nail knives, nail dies, rolling wheels, feeders, wire drawing dies

The automatic nailing machine greatly improves the production efficiency of the nail making operation in the nail making factory, but the equipment problem of the developing machine also comes along. What is the working principle of a nail making machine? The work efficiency is not high? These problems directly affect the performance of the nail making machine, the cost and profit of the nail.

     
UKO-”ten-year-old driver “specializing in the production of various wire tools and nail-making accessories. Founded in 2009 in China's largest cemented carbide production area - Zhuzhou, and began exporting to Southeast Asia, Europe, Africa and other major foreign markets in 2011. Based on long-term cooperation experience with various famous brands, such as MORONI, VITARI, KOVOPOL, WAFIOS, etc., UKO easily solves the problem of machine failure as follows:

Three major faults and troubleshooting methods for the top part of the automatic nailing machine

  1) Top opening: The reason may be that the nail ash or the nail hardness is too high, it is necessary to change the nail or temper, or the nail knife may not be ground, and the nail knife needs to be calibrated according to the regulations.

  2) Nail: There are three reasons for this failure. First, the nail blade is not straight, and the nail knife is sharpened. Secondly, the hardness of the nail blade is too low, and the hardness of the nail knife needs to be improved. Third, the nails are soft and hard, and the nails need to be replaced.

  3) The top is not correct: First of all, the size of the nail knife edge is inconsistent, which is necessary to re-sharp the nail knife. In another case, the position of the cutting edge is wrong, just re-adjust the position of the nail knife.

How to solve the four problems of nail making machine nail cap?

1) No nail cap: This is a common fault. A large part is a reason why the clip is not tight. Just replace the fixture. There is another reason why the nail of the nail cap is reserved. Too short, adjust the length of the reserved nail wire.

2) Nail cap is not round: This problem is usually also on the fixture. Firstly, observe whether the countersunk hole on the fixture is round. If it is not round, it needs to be re-drilled. It is also necessary to observe whether the die hole is uneven or not. smooth. Another possibility may be the problem of nailing or the nail thread reserved for the nail cap is too short, and the length of the reserved nail wire needs to be adjusted, or the nail wire is too hard to punch out the nail cap. Then the nail wire needs to be annealed.

3)Nail cap thickness: also need to check the fixture, see if the height of the two clamps is the same,but also whether the fixture can clamp the nail,  then to observe whether the counterbore of the fixture has single-sided wear In the end, it is necessary to observe whether the nail is too hard and the nail cap that is flushed out is unqualified.

4) Nail cap skew: First, see if the center of the two nail knives is consistent with the center of the nail mold, whether the front and rear heights of the nail knives are neat, and whether the countersink positions of the two nail dies are in the same plane or the shell is loose.

Unexpectedly, it was the customer who taught me the product

Tag: cemented carbide nail tools, the sequence of production lines

When I first entered UKO, a professional supplier of tungsten carbide tools, the first product I received was cemented carbide nail tools (including brazed gripper dies, brazed cutter, punches). In the workshop, I intuitively and clearly understand every link and detail of the production of TC products. However, for the application of products, I can only learn from the company's product catalogue and little information on the network. Unexpectedly, it was my customer who taught me the application of nail tools.

At first, in order to get a better understanding of the customers, I took the initiative to ask the customers what they need to complain after they received the goods.  So I met this particular Indian customer.  He wondered why there were sellers who took the initiative to complain. But after I explained the reason to him, he acknowledged it and introduced their production line in great detail. After our exchange of views, both sides have gained a lot. Next, I have sorted out our harvest in the sequence of production lines.

The first step is wire feeding straightening: the bending steel wire is straightened by friction wheel while the steel wire is transmitted. In the process, attention should be paid to the coordination of wire feeding and straightening. We usually need tungsten carbide brazed gripper dies here. When choosing brazed gripper dies, attention should be paid to the size of wire and the style of nail cap, so as to select the matching model.

Second step, cold heading nail cap: when the nail cap needs to be clamped by clamping mechanism, a section of steel wire is exposed for cold heading nail cap. We usually use movable or swinging stamping dies, collectively known as tungsten carbide punches. Punches are generally divided into threaded punches, mesh punches and plane punches according to patterns. In addition, UKO also provides laser marking services to meet the diverse needs of customers.

The third step, cold extrusion nail tip: extrude the shape of the nail tip through the die, and cut the steel wire at the same time. The tungsten carbide brazed cutter is needed here. It should be noted that nail cutters also have different types of cutter edges for different processing materials and machine speeds. For example, UKO generally recommends slotted nail knives for HSS nail manufacturers to improve the service life of nail knives.

The fourth step is to loosen the clamping mechanism and drop the nails. Be accomplished.
With a set of processes, we can easily find that not only brazed gripper dies, brazed cutter and punches, but also other UKO tungsten carbide products (including wire drawing dies, straightening dies, wire guide dies, etc.) can be used in the nail industry. At the same time, through comparison, we found that although the price of U-shaped alloy block cemented carbide nailing tools is much higher than that of round alloy block products, there is little difference in the application performance of products.

Over the years in UKO, my products have developed from cemented carbide nailing tools to rolls, descaling rolls, drawing dies and so on. I am no longer a green hand, but an old stager in carbide wire products. But I still appreciate that Indian customer. He is not only my customer, but also my teacher and friend.

The nail knife is cracked, the grade is wrong, or the supplier is cutting corners

Tag: Brazed gripper dies,  Brazed cutter, Punches

Nail making machine is the main equipment in the process of nail making. The nail rod, nail cap and nail tip are respectively completed by three parts of brazed gripper dies, brazed cutter, punches. UKO has 16 years experience in producing and exporting nail tools, and we are familiar with the production of these three parts. But a few days ago, I suddenly received a very strange complaint, customers said that our brazed gripper dies,  punches is very good, but nail knife is very wrong!

This nail manufacturer from India found us on the recommendation of UKO's old customers. He reflects that our brazed gripper dies, and punches are better than he used before. But brazed cutter always crack when they are used, just like that they bought before. At the same time, customers have sent us all the suppliers and grade information they have purchased before. Obviously, it's not the first time that they have this problem, and he thinks The problem must be in the selection of the grades.

The grade is YG20C, which is the best one after many tests on the same nail machine. In order to find out the basic reason, We excluded all possible causes with our customers. Customers are also very cooperative, and show us the installation of brazed cutter by video, so that we can rule out the damage caused by the collision of two nail knives. In the video, we suddenly found that the raw materials used by customers were welded scrap. This is the root cause!! Because the hardness of the weld is different from that of other places, when our nail cutter touches the weld, it is easy to damage or crack.

After customers use new raw materials, brazed cutter are no longer damaged without cause. In addition, we also suggest that the wire rod should be put in use after 1 to 3 months before it is put into production. It can increase the service life of tungsten carbide nail tools.

As a professional supplier of tungsten carbide products, UKO is committed to providing tailor-made tungsten carbide solutions for global customers. In terms of wire industry, besides providing nail tools, UKO also has wire drawing die, wire guide die, thread rolling planetary dies, cold rollers, descaling roll and etc. All of UKO wire tools are welcomed by customers around the world. In order to make our tungsten carbide products recognized by our customers, we have a perfect after-sales service system. We also have 337 guarantees for complaints from our customers - reply within 3 hours, formal reply within 3 days and formal solution within 7 days. At the same time, we also provide technical guidance and maintenance services. If you have purchasing plans for cemented carbide nailing tools, please feel free to contact us.

What is cold rolled ribbed steel bar exactly?

                               Tag: cold-rolled ribbed steel bars,  roll production supplier

It is well known that cold-rolled ribbed steel bars have high strength, good ductility, anchorage and other excellent characteristics. What factors make them so unique that they can highlight the encirclement of many steel bars? This will have to talk about its unique performance.

  Cold rolled ribbed steel bar is Ф 6.5 mm ~ Ф 14 mm end of ordinary carbon steel or low alloy hot rolled wire rod for parent metal, cold rolling on the surface after reducing both sides form three sides or crescent cross rib deep processing products. Its bond with concrete anchorage performance good, crack width is smaller than the light round bar, crack resistance is strong, can obviously improve the component state of cracks, cracks become fine and dense.UKO has been committed to exploring the application of subsurface cold rolled ribbed steel bars for ten years, pursuing innovation in production technology, and enhancing the engineering coverage of cold rolled ribbed steel bars with high quality and efficient production process.

And the c which produces it also has the above characteristics.Cast the main reinforcement and distribution reinforcement of floor slab and stair;Due to its large stiffness, it is easy to bind and fix, and it is not easy to trample on deformation, thus ensuring the effective position of steel bars.Stirrup in beam column;The plasticity of cold rolled ribbed steel bars can meet the shear deformation requirements of beams and columns.In addition, LL550 cold rolled ribbed steel bar, especially welded mesh, is also widely used in highway pavement, airport runway, drainage canal, tunnel lining and other projects.
So, every aspect of our daily life has cold rolled steel with rib figure, it is also playing an irreplaceable role.UKO, as a professional manufacturer in China's cemented carbide market, has exported its rolls to hundreds of countries.And has a supporting after-sales service system, professional express service, strict quality control process, is a trustworthy roll production supplier.

Production site for roll ribbed steel bars

Tag:cold-rolled ribbed steel, UKO tungsten carbide roller,  UKO cold roll

I believe many people know that cold-rolled ribbed steel is a kind of building steel with high strength, good ductility and excellent anchoring performance. It can replace the new type of high-efficiency and energy-saving steel with low carbon cold drawn steel wire, and has good economic and social benefits. So how is it produced step by step? Next, explore with the footsteps of mine!

Cold rolled ribbed steel bar is a new type of high-efficiency steel bar which is made by hot rolled round steel bar (wire rod or straight bar) after stripping, reducing diameter, rolling rib and eliminating stress.Most rebar factories in China produce steel in this way. UKO tungsten carbide roller is the main part of the three-roll passive mill, which has strong hardness and high wear resistance, and is produced according to customer requirements, such as lettering and engraving.

Then is the base material, to produce high quality cold rolled ribbed steel bars, good raw materials essential!At present, some large steel companies have or are developing, the production of rolling cold rolled ribbed steel bar special parent material, of course, the production of steel bar machine material is also very important.UKO cold roll 100% in accordance with the production and processing of the corresponding brand.

After cold hardening, the strength of metal material continues to increase with the extension of time, while the elongation further decreases, which is strain aging.By low temperature tempering, the residual stress of cold processed steel can be eliminated, and it is beneficial to metal microcrystallization.Accordingly, processing program also cannot allow careless!

Therefore, can produce high quality cold rolled ribbed steel bars, excellent raw materials and production equipment of the first element!UKO has been committed to the production and sales of cold rolling rollers for ten years, with advanced cold rolling rolling production technology, for hundreds of countries to supply products!And has a supporting after-sales service system, professional express service, strict quality control process, is a trustworthy roll production supplier.

Your cold rolling mill production speed is slower? Jessica has a coup!

                            Tag: cold water shafts, cold rolling mills, work rolls

It is believed that many cold rolled steel producers have encountered slower production of cold rolling mills. The slow speed of the rolling mill directly affects the economic benefits of the company. I once had a customer who bought 10 sets of rolls and I have reflected this problem with me, so I asked for our help.

After we asked the customer about several details of the mill's use and asked the customer to send us a video of the mill operation, we found that the customer's cold water shaft leaked, which caused the coolant to directly contact the roll, making it operate at high speed and high temperature. The lower roll suddenly comes into contact with the cooling water, causing the roll to rupture. So we sent a few cold water shafts to the customer, and later the customer reported that the rolling mill speed was very stable.

In fact, in addition to the problem of leaking cold water shafts encountered by my customers, there are other factors that affect the speed of the mill. Let's take a look at Jessica to see if your mill has encountered the following problems.

1. The slower production speed of the cold rolling mill is most likely due to the friction between the cold rolling mill and the work rolls. Therefore, we usually advise our customers to apply a layer to the rolling mill and rolls every month. lubricating oil. In this way, the friction is reduced and the production speed of the rolling mill is naturally raised.

2. The slow speed of the cold rolling mill is related to itself. Under normal circumstances, it is likely that a large number of roll necks appear inside the bearing of the rolling mill, which is likely to cause movement problems of the rolls. Roller bearing work load is heavy and varies greatly, so the bearing friction coefficient is required to be small, has sufficient strength and rigidity, and it is convenient to replace the roll. For different equipment, the corresponding roll bearing should be used. Generally, the rolling bearing has a large rigidity and a small friction coefficient. The disadvantage is that the pressure that can be withstood is low, and the outer shape is relatively large, which is common in the work rolls of the strip mill.

The above is a small trick to improve the production speed of cold rolling mills, and I hope to have some help for cold rolled steel bar manufacturers. If you have any problems with the use of rolling mill rolls, you can contact Jessica!

Promotion and application of cold rolled ribbed steel in the Chinese market

                      Tag:  cemented carbide roll,  carbide roll supplier

The cold-rolled ribbed steel bar is a steel bar with two-sided or three-sided crescent shape formed by using a cemented carbide roll to reduce the diameter of the hot-rolled wire rod by multiple cold rolling, one pressing rib and eliminating the internal stress. Since the successful development of cold-rolled ribbed steel in Germany, the Netherlands and Belgium in 1968, it has been widely used in Europe (Germany, Austria, Italy, the United States, the United Kingdom, etc.) since 1973. And there are national standards. Driven by the wave of reform and opening up in the 1980s, China began to introduce cold-rolled ribbed steel production equipment, such as rolls, mandrels, and cold water shafts installed on rolling mills. In the mid-1990s, joint ventures or wholly foreign-owned enterprises in Anhui / Guangdong / Jiangsu provinces introduced several production lines from abroad. At the same time, a number of scientific researchers have emerged in China to start research or imitation of refrigeration and rolling equipment. Up to now, there have been more than 400 cold-rolled and ribbed steel production lines in China, with an annual production capacity of 2 million tons, distributed in 26 provinces and cities.

Judging from the situation of the provinces that are known in China, in recent years, under the promotion of national policies, cold-rolled ribbed steel bars have been widely promoted and applied. Thanks to the high strength of the steel, the bond-bonding property with the concrete is good, and the elongation is larger than that of the similar cold-worked steel, and the application in the cast-in-place concrete structure is obviously improved. According to incomplete statistics. In 1998 alone, the national promotion volume exceeded 600,000 tons. In terms of production and application technology, China has developed on the basis of introduction. For example, the tensile strength of steel has been developed from one foreign strength level to three levels: LL550, LL650 and LL800; the application range is also from foreign non-prestressed concrete structures. The component is expanded to a prestressed concrete component.

The China National Science and Technology Commission has included cold-rolled ribbed steel bars in national key promotion projects. In August 1997, the Ministry of Construction named the national cross-century major technology promotion work as “Guangsha Project”, and the promotion of cold-rolled ribbed steel was first implemented as the initial start-up project of “Guangsha Project”. It shows that the country attaches importance to the promotion of cold-rolled ribbed steel bars.
In recent years, the technology of developing cold rolling equipment in China has been in a high-speed development trend. The equipment produced by some domestic manufacturers has reached the international advanced level. Manufacturers of cold-rolled ribbed steel from all over the world have gone to China to purchase carbide rolls and other alloy or steel parts, which has greatly reduced the cost of foreign cold-rolled ribbed steel manufacturers. It also guarantees the quality of the steel bars produced. Of course, there are still some 

manufacturers of sub-filled cold rolling mills and hard alloy rolls in China. Therefore, when you are looking forward to purchasing rolls or rolling mills in China, you must carefully distinguish them. However, for many buyers who are not familiar with the Chinese domestic market, it is not a simple matter to identify a high-quality carbide roll supplier. I will continue to reveal the domestic cold-rolled belt in the following tweets. The production of rib bars and the internal conditions of the domestic carbide roll industry.

Hot Rolled VS Cold Rolled Steel, Is it Only Hot & Cold? You Don't Know the Big Difference?

            Tag:  cold-rolled steel bars,  Carbide wire tools, GB/T 19001-2016 / ISO 9001:2015

Hot-rolled steel bars are directly processed on steel molds in steel furnaces in steel processing plants. They are hot products (so called "hot-rolled") that come out of the furnace and can be used after cooling. In the case of cold-rolled steel bars, the hot-rolled steel bars are further subjected to cold working to obtain steel bars, such as cold drawing and drawing of the steel bars at normal temperature. Carbide wire tools are required for both hot and cold rolled bars. 

We has been focusing on the hard alloy wire mould industry for 20 years and started to expand its international export trade in 2010. It has occupied Southeast Asia, the Middle East, South America and most of Europe, and exports to more than 38 countries. It mainly produces processing rolls and wire drawing dies. The over-line mold, wherein the rolls include cold rolls, hot rolls, dephosphorization rolls, straightening rolls, strain relief rolls, and the like. Our quality testing of raw materials is very strict, the products are sintered under low pressure, and the selection of the grades and the control of the market are very precise. We have a Malaysian customer who once produced a batch of steel bars with a non-performing rate of 30%. Originally, he purchased some rolls from other suppliers for price reasons. Later, according to the information provided by the customer, we analyzed the use of the roll number. . And because our profession has now become our loyal VIP customer, we will roll down every 2-3 months, and we will continue to maintain a good relationship.

The difference between hot rolled and cold rolled steel: the difference between the two is not only the difference between heat and cold, but the strength between them, the yield point, and the tensile strength, etc., then we Let's take a look.

1. Hot-rolled steel bars are finished steel bars that have been hot-rolled and naturally cooled. They are pressed from low-carbon steel and ordinary alloy steel at high temperature. They are mainly used for reinforcement of reinforced concrete and prestressed concrete structures. One of the most used steel products in the project. Generally, steel bars with a diameter of 6.5 to 9 mm are mostly rolled into wire rods; straight wires having a diameter of 10 to 40 mm are generally 6 to 12 meters long.

2. The cold-rolled steel bar is obtained by cold-rolling the hot-rolled steel bar to obtain the steel bar. For example, the steel bar is cold drawn and drawn at normal temperature. These processes require the use of a cold roll, a drawing die and the like. Hot rolled steel has lower yield strength and good plasticity. Cold-rolled steel has high yield strength and poor plasticity, and the ultimate tensile strength is the same.

3. Third, hot-rolled steel and cold-rolled steel bars can be seen at a glance which hot rolling which is cold rolling?

Hot-rolled steel bars are ‘H’, such as hot-rolled ribbed HRB335, HRB40, etc., cold-rolled steel bars are “C”, such as cold-rolled ribbed steel bars CRB550, CRB650, etc. Everyone remembers what letters are hot-rolled and cold-rolled steel, and it's easy to tell.

We specializes in exporting cold-rolled ribbed steel rolls (FO/CA/RT/RO/PR), and provides de-phosphorus sticks, straightening rolls, stress-relieving rolls, mandrels and other steel wire rolls, which can provide customers with one stop.

The Market Coverage of Cold-rolled Ribbed Steel Bars is as High as 80%, & it Has a Long History of 51 Years

                          Tag: ribbed steel bars,  UKO cold-rolled, dephosphorization rolls

The cold-rolled ribbed steel bar is a steel bar with two-sided or three-sided crescent shape formed by hot-rolling wire rod through multiple cold rolling reductions, one pressing rib and eliminating internal stress. In 1968, Germany, the Netherlands, and Belgium developed successfully. Since 1973, it has been widely used in Europe (Germany, Austria, Italy, the United States, the United Kingdom, etc.) and has corresponding national standards. The International Organization for Standardization (ISO) has also established international standards.

UKO has been focusing on the production and processing of cold-rolled ribbed steel rolls (FO/CA/RT/RO/PR) for 16 years and is equipped with de-phosphorus sticks, straightening rolls, stress-relieving rolls, mandrels, and other steel wire rods. It can provide a one-stop service for customers and has ISO certification (GB/T 19001-2016 / ISO 9001:2015).

  

As a kind of construction steel, cold-rolled ribbed steel is included in the concrete structure specifications of various countries and has been widely used in construction engineering, highways, airports, municipalities, and hydropower pipelines. In 1994, the European Union produced 4.5 million tons per year. In China's neighboring countries, Singapore and Malaysia have long been widely used in construction and municipal engineering. The annual usage of cold-rolled ribbed steel in Singapore alone is over 150,000 tons. It can be seen that the market potential of cold-rolled ribbed steel bars is very large. UKO cold-rolled ribbed steel bars have been exported to no less than 80 countries. There are agents in Malaysia, Thailand and other places, quality service, and rolls. The high-cost performance of the UKO has won the praise of customers.

The strength grades of cold-rolled ribbed steel bars are roughly the same in all countries, both above and below 550Mpa, and the specifications are 4-9mm. They are used for ordinary reinforced concrete structures, such as cast-in-place slabs, foundation slabs and distributed ribs, and distribution of shear walls. Ribs, stirrups of beams and columns, etc. These ribbed steel bars rolled out by the cold rolling of UKO low-pressure sintering can be perfectly used in construction projects. The mechanical properties of steel bars specified in the international standard ISO10544-1992(E) are as follows: yield strength 500Mpa, tensile strength 550Mpa, elongation (standard gauge 5 times diameter) is 12% (Note: China's set elongation δ10 ≥ 8% Instead of δ5 ≥ 12%). The tensile properties shall be at least 90% of the total number of tests equal to or greater than the specified characteristic value, and the individual test results shall be not less than 95% of the specified characteristic value. Choose UKO professional cold roll suppliers to greatly improve your steel tensile properties and customize the ribbed pattern you want.

Most of the cold-rolled ribbed steels are used in the form of welded wire mesh, and a small number of straight steel bars are used for binding on the site. Among them, there are 19 welded wire mesh factories in Germany, belonging to 6 groups. Regardless of whether it is a straight bar or a welded wire, it is factory-produced and sent to the construction site in batches according to the construction schedule. The steelworkers need only lay them out according to the drawings, and no further processing is required.

UKO specializes in the production of hot and cold rolls, dephosphorization rolls, straightening rolls, drawing dies, over-line dies, and other wire tools, providing roll fittings for a wide range of wire equipment, greatly improving the production efficiency of cold-rolled ribbed bars and reducing raw materials and Machine loss. Our rolls are professionally tailored to provide laser engraving for our customers, and UKO customers have a lifetime after-sales service system.

Do you really know the difference between cold and hot-rolled ribbed steel bars?

Tag:  cold rolled 

With the rapid development of the economies of various countries, especially the rapid increase in the demand for construction steel, it is urgent to further accelerate the quality and renewal of building steel bars. You can see many wire mesh in many construction sites. Maybe you know that these crescent-shaped steel bars are cold-rolled ribbed steel bars or hot-rolled ribbed steel bars. They are all steel or steel plates. In the molding process, they have a great influence on the organization and performance of the steel bars. There are differences between the two types steel bars, but do you really know the specific difference between cold and hot-rolled ribbed steel bars?

I was also unclear at the beginning. After entering RELINK,  I had a basic understanding of the differences between cold rolled ribbed steel bars and hot rolled ribbed steel bars through the explanation of my colleagues. Later, through the introduction of an enthusiastic Romanian customer, Gabriel, an experienced technology manager from a manufacturer of steel bars. I had a deeper understanding of the differences and their advantages and disadvantages. He bought the 125*82*15mm our tungsten carbide cold roll of PR6.0, and reflected that the cold-rolled ribbed steel bar produced by roller from RELINK fully conforms to the standard of KARI488 PROFILE. The roller is wear-resistant, and he is satisfied with the quality and price, and happy to tell us about their main products. Here, I would like to especially thank my valuable customer Gabriel for his detailed and patient explanation.

Here are the differences for cold and hot ribbed steel bars:

1. Different processing techniques.

The hot-rolled steel bar passes the gap (various shapes) of the pair of rotating rolls at a high temperature at a high temperature, and the pressure is processed by the compression of the rolls to reduce the cross-section of the material and increase the length. Usually expressed in HRB, for example, HRB500, there are often large diameter steel bars with specifications Φ6-Φ25. Cold-rolled ribbed steel bars are made of hot-rolled round steel bars (wire bars or straight bars), which are stripped and reduced in diameter, ribbed and stress-relieved to form a new type of high-efficiency steel bar. Usually expressed in CRB, for example, CRB550, often has small steel bars such as Φ4-Φ14mm;

2. Physical properties are different.

Hot rolled steel bar has low yield strength and good plasticity. While cold rolled steel bars have high yield strength and poor plasticity. The yield strength of hot-rolled reinforcement HRB500 is above 500Mpa, and its elongation after fracture is more than 15%. The yield strength of cold rolled steel bar CRB550 is above 500, and its elongation at break is more than 4%.

3. Different applications.

The cold-rolled ribbed steel bar has three sides with ribs, good roundness, convenient opening and straightening, good welding quality and low price. It is suitable for the distribution of cast-in-situ slabs, the distribution of shear walls, the stirrups of beams and columns. And the reinforcement of the ring beam. Because of its good ductility, hot-rolled ribbed steel bars are suitable for reinforcement of components with seismic requirements, in addition to reinforced concrete slab structures.

As a professional manufacturer of tungsten carbide rolls with over 19 years of experience, RELINK has been providing high quality and durable tungsten carbide rolls to over 500 customers around the world. Just tell us the roll cassette speed and size of steel bar, or send steel bar sample to us, we will provide the most suitable solutions of tungsten carbide roll.

High-quality Nails Double the Annual Revenue of your Enterprise

Tag:  nailing tools,  uko

As the professional manufacture of nailing tools, UKO provides high-quality products for all the clients.During the nailing process, nail dies will encounter a various of problems, the nail skew is the most common problem. There are two general reasons: one is that nail knife is skewed or broken; the other is that the nail die on the nail machine is loose.How to solve the problem that the nail produced by the nail machine is skew? According to the above reasons, if it is the nail knife skew or the nail knife damaged, then you should check whether the nail knife is damaged and skewed, if the nail knife is skew, the nail production must be skew. 

Therefore, it’s necessary to pay attention to the routine maintenance of the nail dies and the nail knife parts in the equipment.If the nail die and the nail knife part in the equipment are loose, then you should check first to confirm whether it is the problem, and adjust the nail die to the normal operating condition to avoid the nail skew.There are three general reasons that the nail tip produced by nail die is not straight or curved: the first is nail die loose; the second is that the nail blade edge does not meet the requirements; the third is improper adjustment of shear mechanism.

Poland's Complex-Partner Sp. z o.o. is a partner of the UKO’s integral alloy of nails knife and nails dies. With the stable quality supply in 2016, UKO has recognized by customers. In mid-2017, the customer feedback quality problems of nail die products, the nails produced by our nail knives and nail dies were skewed and could not meet the nail requirements in the Polish market. The customers were angry and became doubt about our manufacturing technology. 

As a enterprise with 16 years of export experience, UKO has a perfect after-sales system which providing a set of procedures for handling customer questions. We ask the customer for sending the pictures of the nail knives after use, the finished product of nail, and the video of whole production process. After professional analysis by engineers, the main reason was that the nail die was loosely installed in the nail machine. 

After giving the improvement plan and free new punch of nail die and nail knife for re-tested. The customer replied a mail of thanks that the nails production became normal for our professional advice, and they would recommend other nail customers in Poland for us.UKO specializes in the production of nail knives and nail dies punches, providing professional one-stop service for fastener customers, including welding nail knives, welding nail dies, welding rams, integral alloy punches, nail knife and nail die blanks, feeder, toolbar, replaceable nail dies and nail knives. The punches of nail knife and nail die provided by UKO are suitable for MORONI VITARI, KOVOPOL, WAFIOS.More products information are available on UKO’ website: www.ukocarbide.com and www.ukowiretools.com.
