Cemented carbide roll rings (also known as tungsten carbide roll ring) possesses good thermal conduction property. Compared with pther materials, it is much better in terms of heat-resistance, wear-resistance and strength. What’s more, it shardness reduces a little under the condtion of high temperature. So, the cemented carbide roll rings is invented with the ap-pearance of high speed wire rod mill. With the development and improvement

Application: it is widely applied in the production of high speed wire, bar and deformed steel bar.


We can supply them accrding to the drawings provided by customers
