Cemented carbide roll rings also known as tungsten carbide roll ring possesses good thermal conduction property. Compared with other materials, it is much better in terms of heat-resistance.wear-resistance and strength. What's more,its hardness reduces a little under the condition of high temperature. So the cemented carbide roll rings is invented with the appearance of high speed wire rod mill. With the development and improvement, it is widely applied in the production of high speed wire, bar and deformed steel bar.
