Abstract

PURPOSE: To provide uniform composition, excellent wear resistance, and casting property by a method wherein graphite vermicular agent and Sb are added to spheroidal graphite cast iron having a relatively high C equivalent and a low S content, and contg. graphitization agent such as Mg to control precipitation of soft ferrite.
CONSTITUTION: Spheroidal graphite cast iron contg. C: 3W3.7%. Mn: 0.3W1%, P: 0.05W0.15%, S: 0.01W0.03% and Si: 2W3% is melted. To this molten metal, Ti: 0.02W0.09% and Sb≥0.02% (preferably 0.02W0.12%) are added as a graphite vermicular agent. Then, Mg is added as graphatization agent so that (Ti+Sb)/ Mg≥5 holds. This method controls precipitating soft ferrite and eliminates nonuniform composition due to cooling rate difference caused by various wall thickness of cast products.
