ABSTRACT:
A method for making cast iron containing globular or nodular graphite wherein molten iron is poured into magnesium or a magnesium master-alloy which is covered with particulate silicon carbide and iron chips. This covering results in minimization of the oxidation of the magnesium and is also advantageous in maintaining the temperature of the molten iron.
