Abstract

PURPOSE: To prepare CV graphite cast iron easily by adding and mixing general molten cast iron to molten cast iron to which spheroidizing treatment of graphite is applied in a specific ratio.
CONSTITUTION: A graphite spheroidizing agent such as Mg, Ce or the like is added to the molten metal of scale like cast iron to spheroidize graphite and Fe-Si or the like is further seeded therein to form a molten spheroidized cast iron and 20W80% of general scale like graphite cast iron melt is added thereto to sufficiently stir the resulting mixture. By this method, CV graphite cast iron can be prepared easily and stably.
