Abstract

PURPOSE:To make the surface construction dense to prevent a meteoric flaw and a scale banding, by welding and padding the steel, where the composition ratio is limited, to a roll body part. CONSTITUTION:The small-diameter roll is used as the core bar to weld and pad the steel consisting of 0.5-1.2wt% C. 0.3-1.2wt% Si, 0.2-1wt% Mn, 2-20wt% Cr, 0.2-2wt% Mo, <=1wt% V, <=2wt% W, 0.1-0.5wt% S or/and P, and rest Fe to the body part by the multielectrode method with this steel as the electrode. Next, this roll is forged and processed mechanically after subjecting it to the diffusion processing at 1,200 deg.C. Next, it is quenched and tempered to finish a working roll for hot rolling. C has the influence upon the quantity, the form, and forging of cementite. Si is used as a deoxidizer and improves quenching and tempering. V is of use for making crystal grains minute, and S and P improve the resistance to casehardening.
