Description
tungsten carbide mill roll for hot mill‘s application:
have high hardness, and the hardness value is rather small, along with the change of temperature of 700 ℃ when the hardness value is four
times that of high speed steel;And modulus of elasticity, compressive strength, bending strength, thermal conductivity were also higher than that
of tool steel more than 1 times.Due to their high thermal conductivity of carbide roll,So the cooling effect is good, make the roll surface at high
temperature time is shorter, thus make the roll cooling water with harmful impurity in the high temperatureThe reaction time is shorter.Therefore,
the cemented carbide roll more than tool steel roller corrosion resistance, resistance to cold and hot fatigue.
Various grades of WC carbide flat rolls, rollers, slotted rolls
