Abstract

PURPOSE: To prevent body fracture and metal fracture by casting an outside shell through centrifugal casting by the use of a cast iron roll material, and pouring the spheroidal graphite cast iron of specific composition into the hollow part of the outside shell thereby making the outside shell stronger and tougher.
CONSTITUTION: An outside shell is cast to a hollow shape through centrifugal casting by using an ordinary cast iron roll material, and after the solidification of the shell, the spheroidal graphite cast iron consisting of 3W3.7 C, 1.5W2.5 Si, 0.2W 1 Mn, <3 Ni, <0.4 Cr, <1 Mo, 0.02W0.1wt% Mg, and the balance Fe and unavoidable impurities is poured as an inside shell into the hollow part of the outside shell and is melt-stuck thoroughly. This roll-shaped blank material is heated to 780W840°C, after which it is air- or water-cooled.
