How to efficiently understand the use and classification of cemented carbide rolls

       Cemented carbide rolls are one of the materials that are in large demand by steel mills. They are mainly divided into four categories: high-speed wire rolls, a new generation of high-speed wire hot rolls, a new generation of high-speed wire review rolls, and cold-rolled three-dimensional rolls.



The cemented carbide roll produced by our company has good thermal conductivity, high wear resistance and corrosion resistance, and good general performance. It significantly reduces the depth and width of hot cracks in the rolling groove during rolling, and reduces roll chipping danger.

Compared with the high-speed wire hot roll, the new generation of high-speed wire hot roll has higher impact resistance, thermal fatigue resistance, and high wear resistance. It is suitable for high-speed wire rolling with a speed of more than 100 m/s.



 On the front frame of the finished product of the rebar and bar rolling mills, the use of a new generation of high-speed wire rod composite rolls can greatly reduce the number of slot changes and roll changes, reduce labor intensity, improve labor production efficiency, and improve the surface quality and percentage of finished products In order to obtain significant economic benefits.

 Cold-rolled ribbed steel bars are rolled by cold-rolled three-dimensional rolls. The surface of the steel bars is beautiful, the dimensional accuracy is high, and the ribs are clear. At the same time, the performance of the ribbed steel bars is changed and the strength is improved. The rolling volume at one time has reached (800-1500 tons), which is (20-50) times higher than that of ordinary tool steel materials. It can be used repeatedly for grinding, greatly reducing costs, and significantly improving benefits and efficiency.
