摘要
PURPOSE:To produce a roll stock improved in cracking resistance and slip resistance while maintaining wear resistance by preparing a high chromium cast iron roll stock having a specific composition in which C content is reduced. CONSTITUTION:A high chromium cast iron roll stock which has a chemical composition consisting of, by weight, 1.3-2.0% C, 0.3-1.5% Si, 0.3-1.5% Mn, 0.5.2.4% Ni, 11-19% Cr, 0.8-3.0% Mo, and the balance essentially Fe and containing, if necessary, 0.1-1.0% Ti or 0.1-1.0% Nb in place of a part of Fe is prepared. By this method, the high chromium cast iron roll stock excellent in cracking resistance and slip resistance while maintaining wear resistance can be obtained. This stock can be used mainly for the outer layer of a composite roll for hot rolling.
