The application of carbide roller is very wide，which can be applied to the production of wire rods, pipes，etc.They all improve the performance of rolling mills.
Types of Cemented Carbide Rolls
Cemented carbide rolls can be divided into two types: solid carbide rolls and composite cemented carbide rolls. Solid carbide rolls have been widely used in pre-finishing and finishing stands of high-speed wire rod mills.
The composite cemented carbide rolls is composed of cemented carbide and other materials and can be divided into cemented carbide composite roll ring and integral cemented carbide composite roll. The cemented carbide composite roll ring is installed on the T.C rolls holder; the overall cemented carbide composite roll directly casts the cemented carbide roll ring in the roll shaft to form a whole, which is applied to the rolling mill with a large rolling load.
The groove life of cemented carbide composite roll rings is about 10-20 times that of ordinary cast iron rolls, and the amount of each grinding is only 1 / 2-1 / 3 of the cast iron rolls. Therefore, compared with traditional cast iron rolls, the hard The total rolling volume of alloy composite roll rings is 20-40 times that of ordinary rolls.
Usage of Tungsten Carbide Rolls
Tungsten Carbide is not affected by changes in the environment or external temperature so these rolls can be used in either extreme heat or extreme cold.
Tungsten carbide rollers ( T.C. rolls or TC Rollers ) are valued for their hardness and resistance to corrosion and, since they can withstand an elevated level of stress, they are the ideal choice for clients in the aeronautic and aerospace industries, the automotive industry and the bearings industry. They are often found in power steering columns or transmission and navigation equipment and can also be used for vibro finishing.
In the process of rolling high-speed wire rods, the amount of single-pass steel in the carbide roll is much higher than that of chilled cast iron or high-speed steel rolls.
Processing of Tungsten Carbide Rolls for Rolling Mill
In the early stage, the grinding process was adopted to process carbide rolls and roll rings, but the grinding efficiency was too low, which affected production efficiency.
After years of experience in carbide roller manufacturing, Zhuzhou UKO, as a TC roll manufacturer for rebar mill, has core competitiveness and unique product production, sales and service advantages in the industry.
Through practice and repeated experiments, the material of the cutter that can be replaced by turning is finally developed. Turning is used to replace the rough grinding process, which greatly improves production efficiency and reduces production costs.
Ribbed tungsten carbide roller are ideal for use in applications where strength, durability and longevity are factors. Tungsten Carbide (WC) is twice as strong as steel and is similar to corundum in hardness. It has a Young’s Modulus rating of 530–700 GPa (77,000 to 102,000 ksi) and the material is twice as dense as steel. Tungsten carbide rollers combine superior hardness with resistance to abrasion and wear and they are available in a wide range of sizes. They can also be milled according to the customer’s specifications.
