Tungsten carbide roll rings has good heat transfer performance, low hardness drop and high thermal fatigue resistance at high temperature Good wear resistance, high strength, etc. These characteristics are difficult to achieve with other materials. Therefore, since the advent of the high-speed wire rod mill, the tungsten carbide roll rings has emerged as the times require, and has been continuously developed and perfected. It has been widely used for rolling production of high-speed wire rods, bars and rebars.
