Abstract

PURPOSE: To obtain a composite sleeve roll for rolling H-steel with high performance having desired outer shell hardness by fusing and integrating a high Cr steel outer shell with a specific composition and an inner shell of spherical graphite cast iron by a centrifugal casting method.
CONSTITUTION: By a centrifugal casting method, an outer shell molten metal of a high Cr steel material containing 2.0W3.2% C, 0.5W1.5% Si, 0.5W1.5% Mn, 10W25% Cr and a specific amount of P, S, Ni, Mo or the like is cast. During a time when a part or an entire part of an inner surface thereof is not solidified, an inner shell molten metal of a spherical graphite steel material containing 1.0W2.0% C, 0.6W3.0% Si, 0.2W1.0% Mn and a specific amount of P, S, Ni, Cr, Mo or the like is cast and the inner and the outer shells are integrated by fusion bond. By this method, a composite sleeve roll for rolling H-steel having outer shell hardness of 65W85Hs and excellent in abrasion resistance or the like is obtained.
