Abstract
PURPOSE: To obtain a composite sleeve roll for rolling H-steel having a desired outer shell hardness by fusing and integrating a high Cr steel outer shell having a specific composition and an inner shell comprising spherical graphite cast iron through an intermediate layer with a specific composition by centrifugal casting.
CONSTITUTION: By centrifugal force, an outer shell moltem metal comprising high chromium steel containing 2.0W3.2% C, 10W25% Cr and a specific amount of Si, Mn, P, S, Ni, Cr, Mo or the like is cast. Subsequently, during a time when an inner surface thereof is not solidified, an intermediate layer molten metal comprising a steel material containing 1.0W2.0% C, 0.2W2.0% Si, 0.3W 2.0% Mn and a specific amount of P, S, Ni, Cr, Mo or the like is cast. During a time when the inner surface thereof is not solidified, an inner shell molten metal of spherical graphite cast iron containing 2.8W3.8% C, 1.8W3.2% Si, 0.3W 2.0% Mn and a specific amount of P, S, Ni, Cr, Mo or the like is cast and the outer shell, the intermediate layer and the inner shell are integrated by fusion bonding. By this method, a composite sleeve roll with outer shell hardness of 65W80Hs is obtained.
