Tungsten carbide rings it is widely applied in the production of bar, high wire and deformed steel bar. It is usually used at the front stand of finishing mill, the last stand of finishing mill and the pre-finishing mill.cemented carbide roll rings (also know as tungsten carbide roll ring )possesses good thermal conduction property.compared with other material, it is much better in terms of heat-resistance, wear-resistance and strength.what's more , its hardness reduce a little under the condition of high temperature.so the cement ed 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.
