Cemented carbide roll ring, also known as Tungsten carbide roll ring, possesses very good thermal conductivity property. Under the condition of high temperature, compared to other materials, the hardness keeps stable and it provides much better heat resistance, wear resistance and strength.

The cemented carbide roll ring has been invented with the appearance of high speed wire rod mill, it is now widely applied in the production of high speed wire, bar and thread rod steel. Its hardness and wear resistance come from tungsten carbide (Wc) while the toughness and strength depend on the binding agent (Co-Ni-Cr).
