Features of Tungsten Carbide Roller with Ribbing for Rolling Mill :
Tungsten carbide roller ring is a kind of metallurgical tool which consists of tungsten carbide and cobalt with high hardness and wear resistance. There are ideal for use in applications where strength, durability and longevity are factors. The performance of the tungsten carbide roller is related to the content of the bonding phase metal and the size of the matrix phase--the tungsten carbide powder particle.The different binder content and the corresponding tungsten carbide particle size form different carbide grades. If the content of the metal binder is increased or the particle size of the tungsten carbide is increased, the hardness of the cemented carbide decreases and the toughness increases. Tungsten Carbide (WC) is twice as strong as steel and is similar to corundum in hardness. 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. It has advantage of high wear resistance, long life and high efficiency during the high speed rolling.
Application:
Cemented carbide roller used on the stretch reducing mill for bars, thread steel bars and common wire with the durability 10 to 20 times higher compared to common steel roller. The surface quality and the steel bar size accuracy are greatly improved. The cemented carbide roller reduces effectively the production cost and improves the quality. Roller for Profile Wire Rolling, Flat Wire Rolling, Construction Wire Rolling, Plain Wire Rolling and Welding Wire Rolling, Wire Straightening, Wire Guiding etc. Important is we have the development group that can offer new grades for customer.
