Tungsten carbide roller rings

Various wires and rods guiding rolls are available with your special request.

The products are widely used in the rolling of high carbon steel, alloy steel and plain carbon steel such as steel cords, steel strands and alloy welding wires. The supporting imported rolling mills include MORGAN, DNAIELI, SMS, POMINI, KRUPP and domestic high-speed rolling mill units.

The cemented carbide composite roll is mainly used on the finishing mil for bar, deformed steel bar and common wire. In this way, wecan greatly reduce the frequency of changing groove and roll, thus to reduce the labor intensity and improve the work efficiency. Thesurface quality and yield shall be improved to a maximum degree, which leads to a remarkable economic benefit.Our cemented carbide composite ro adopts a special grade of cemented carbide. By means of hydraulic lock nut, the cementedcarbide roll rings is fastened to the axle with the axial pressure of 200Mpa from hydraulic ol. Under the protection of prestress, thecemented carbide composite roll shall work more effectively.
