Abstract
PURPOSE: To perform spheroidization of graphite uniformly and satisfactorily over the entire part of the wall thickness in a spheroidal graphite cast iron part by decreasing the residual amt. of Mg of the molten metal for the outside layer part of a cylindrical body and increasing the same of the molten metal for the inside layer in centrifugal casting of the cylindrical body with spheroidal graphite cast iron.
CONSTITUTION: While a metallic mold 6 provided with sand molds 8, 9 for forming roll neck parts in both end parts is rotated, the molten cast iron added with Mg which is a graphite spheroidizing agent is cast in such a way as to make the residual Mg 0.03W0.05% after the graphite spheroidization treatment, whereby an outer layer 10 is centrifugally cast. Next, an Fe-Si-Mg alloy is added to the remaining melt in a ladle 13 to make the residual amt. of Mg to 0.05W0.1%, whereby the 2nd layer 11 is formed on the inner side of the outer layer 10 of the metal mold 6, so that the outside shell layer of uniform graphite spheroidization is formed by both layers 10, 11. Next, the mold 6 is erected still, and the melt of strong and tough cast iron for a core material is cast in one body with the outside shell layer, whereby the composite roll is produced.
