Tungsten carbide roll rings introdcution

With the increasingly fierce competition in the quality and price of steel products,steel companies are constantly updating their equipment technology to continuously increase the rolling speed of rolling mills. At the same time, how to reduce the number of rolling mills and further improve the effective operation rate of rolling mills. It has become an important topic for rolling steel engineers. The use of roll materials with higher rolling life is one of the important means to achieve this goal.

Due to its good wear resistance, high temperature red hardness, thermal fatigue resistance and high strength, cemented carbide rolls have been widely used in the production of rods, wires, rebars and seamless steel tubes, which greatly improved the rolling mill. Effective operating rate. According to the difference of working environment of each rack roll, various grades of carbide ring have been developed.
