The cemented carbide composite roll is mainly used on the finishing mill 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 roll 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 20OMpa from hydraulic oil. Under the protection of prestress, thecemented carbide composite roll shall work more effectively.

Our Client Say?

The trial data shows that the ∮370mm high-speed steel roll produced by LMMGROUP has far exceeded the single-groove assessment value of 1,500 tons in the “Roll Ordering Technical Agreement”, and the effect is good.

On September 10, 2015, in the rolling process of the steel rolling mill, the LMMGROUP high-speed steel bar rolling experiment was carried out on the first bar line C12 to four cuts, and C14 three cuts to K1, K2, K3, and K4. According to the trial situation, The average amount of steel passing through LMMGROUP rolling is about 50%-60% of the alloy rolling spoke. The processing difficulty of high-speed steel is low, and the processing cost is lower than that of the alloy rolling wheel. Our factory can achieve normal processing.
