Tungsten carbide rolls ring operating characteristic

Tungsten carbide rolls ring have high hardness, and their hardness values change little with temperature. The hardness at 700 °C is 4 times that of high-speed steel; and the modulus of elasticity, compressive strength, flexural strength and thermal conductivity are also high. More than 1 times the tool steel. All these properties ensure that the tungsten carbide roll has much better wear resistance and deformation resistance during the working process than the tool steel roll, thus ensuring the smoothness and dimensional stability of the roll groove, which ensures the surface quality of the wire. And dimensional accuracy is critical. Since the tungsten carbide roll has high thermal conductivity, the heat dissipation effect is good, and the surface of the roll is at a high temperature for a short period of time, so that the high temperature reaction time of the roll and the harmful impurities in the cooling water is short. Therefore, the tungsten carbide roll is more resistant to corrosion and cold and heat fatigue than the tool steel roll.
