Abstract
PURPOSE:To manufacture a supeior high hardness roll at a low cost by forming a composite roll by centrifugal casting using Adamite material as a material for the outer shell part and specified spheroidal graphite cast iron as a material for the core part and by subjecting the composite roll to special heat treatments. CONSTITUTION:A composite roll is manufactured using Adamite material as a material for the outer shell part and cast iron consisting of, by wt., 2.8-3.6% C, 1.6-2.5% Si, 0.1-0.5% Mn, <=0.1% P, <=0.02% S, 0.5-1.5% Ni, 0.1-0.3% Cr, <=0.5% Mo, 0.02-0.1% Mg and the balance essentially Fe and having 45-55kg/ mm.<2> tensile strength and 1.0-2.0% elongation as cast as a material for the core part. The outer shell part is subjected to diffusion annealing, spheroidizing annealing and hardening, and the whole roll is tempered. Thus, a high hardness Adamit roll with Hs 60-75 outer shell hardness is obtd.
