Tungsten Carbide Roll Rings Description
The cemented carbide roll is a roll made by a powder metallurgy method using tungsten carbide and cobalt as materials. Carbide rolls are available in both integral and combined versions.
Tungsten Carbide Roll Rings Feature:
The cemented carbide roll has high hardness, and its hardness value changes very little with temperature. The hardness at 700 °C is 4 times that of high speed steel; and the elastic modulus, compressive strength, flexural strength and thermal conductivity are also More than 1 times higher than tool steel. Since the thermal conductivity of the cemented carbide roll is high, the heat dissipation effect is good, and the time at which the surface of the roll is at a high temperature is short, so that the high temperature reaction time of the roll and the harmful impurities in the cooling water is short. Therefore, the cemented carbide roll is more resistant to corrosion and cold and hot fatigue than the tool steel roll.
