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.
The cemerted carbtide composite roll i mainly used on the finishing rnill for bar, deformed steel bar and common wire. In this way, wecan greatly reduce the frequency of changing grove and rol, thus to reduce the labor intensity and improve the woik efficiency. Thesurface quality and yield shall be improved to a maximum degree, which leads to a remarkable economic benefit.
Our cemerted carbide compcsite roll adopts a special grade of cemented carbide.By means of hydraulic lock nut,the cementedcarbide rollrings is fastened to the axle with the axial pressure of 2OOMpa from hydraulic oil. Under the protection of prestress, thecemented carbide composite roll shall work more effectively.
