Description

Adopting bimetallic composite extrusion casting process, the structure is dense, with high red hardness, wear resistance, impact resistance, and processability. It is not easy to produce pockmarks, peeling, or slotting during use; It can reduce intermediate rolling waste caused by rapid wear of the rolling groove, thereby improving the yield of the product; Reduce the number of roll and groove changes to improve the operation rate of the rolling mill; Good wear resistance, able to effectively control negative deviation rolling.
