Solidification of molten metal from bottom to top is beneficial to the feeding of liquid metals. Because there is no density segregation in the special casting method, Sendzimir work roll can be made of high carbon, high tungsten and high vanadium high speed steel with good red hardness and high temperature wear resistance. The outer layer of Sendzimir work roll solidifies in water-cooled crystallizer to obtain fine solidification structure and improve the strength, toughness and thermal fatigue resistance of Sendzimir work roll. The use of forged steel as core material has high strength, and there is no risk of core fracture during rolling, and the bending load of Sendzimir work roll is increased, so that the rolled steel plate has a better shape.
