Abstract

PURPOSE: To provide an Si-Mg type graphite spheroidizing agent for cast iron that can reduce the production of slag in particular considerably by contg. a prescribed amt. of rare earth elements and specifying the contents of Al and Ca respectively at prescribed value or below.
CONSTITUTION: An Si-Mg type spheroidal graphitizing agent contg., in general, about 20W75% Si, about 0.5W7.0% Mg, and ≤2.8% rare earth elements. The Al and Ca to be further contained in this graphite spheroidizing agent are specified respectively at ≤0.5%. Molten cast iron is treated by the resultant graphite spherodizing agent, whereby the production of slag on the surface of the molten metal is suppressed considerably, and the need for slag removing work is eliminated.
