Tungsten carbide roller has high hardness, and their hardness values change little with temperature. Its hardness at 700°C is 4 times that of HSS.And the elastic modulus, compressive strength, bending strength, and thermal conductivity are also higher than the tool steel by more than one time.Due to the high thermal conductivity of the tungsten carbide rolls, the heat dissipation effect is good.Therefore, the cemented carbide rolls are more resistant to corrosion and cold and heat fatigue than the tool steel roll.
Tungsten carbide rollers main used to produce smooth or ribbed wire for construction reinforcement filed
