ABSTRACT:
A method of producing cast iron including the steps of providing an initial cupola charge having a silicon content less than the silicon content required, melting the charge, conducting the melt to a mixing vessel, substantially increasing the silicon content of the melt by adding granular silicon carbide to the mixing vessel while simultaneously agitating the melt to achieve a good mix and conducting the silicon-enriched melt to a holding vessel or a molding line.
