Cast iron alloy and method for producing same

摘要

A composite cast iron alloy used as a material for nonferrous metal casting equipment. The raw materials for the composite cast iron alloy include iron, calcium-containing substances, coke, titanium compounds, silica, compounds containing graphite stabilizing elements and aluminum metal. The raw material for the iron is pig iron, scrap and steel and the titanium compounds are either alkaline metal titanates or alkaline earth metal titanates. The composite cast iron alloy is produced by first melting and reacting the iron raw material with calcium containing substances, coke and titanium compounds to obtain melted iron material for casting, mixing the melted iron material for casting with aluminum metal and casting the mixture into a composite alloy.
