Abstract

PURPOSE: To enhance the wear and spalling resistances by adding a specified amount of C, Si, Mn and Cr to steel products for a roll, allowing the relation between C and Cr to satisfy specified 2 equations at the same time, adding a specified amount of Mo and/or V, and regulating the surface hardness to a specified value.
CONSTITUTION: The composition of steel products is adjusted to, by wt., 0.6W 1.6% C, 0.15W1.6% Si, 0.15W1.6% Mn, 3.5W15% Cr, 0.4W3% Mo and/or 0.2W 2% V and the balance Fe with impurities. The relation between C and Cr in the composition satisfies relational equations I, II at the same time. The steel products are hardened and tempered to regulate the surface hardness to Hv 620W750. An intermediate roll for a 6- high rolling mill is manufactured using the steel products. To the composition may be added <1% Ni.
