Abstract: In this paper, the investigation of the test procedure of the production of compacted graphite cast iron with high-sulfur melted iron in the cupola has been introduced, treated by XtMg5-6 alloy. The present paper has described the production technique and control method, resera-ch on chilling tendency and compacted effect failure of this Compacted graphit iron hao been andertaken, other existing proptemsof this compacted graphit iron has been poinded out also.
