Tungsten carbide composite roll

Composite roll is the carbide roll ring and steel shaft with special methods, which is used for rolling round bar steel, rebar, square steel, flat steel, Angle steel and other profiles. Application to traditional rod mill and rod-wire mill, high-speed wire mill, corner steel, square steel and flat steel within 2-50 m/s.....

 Tungsten Carbide 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.
