ABSTRACT:
A method of producing cast iron wherein kish is added to either the molten iron or to the metal charge. Kish is graphite which floats to the surface of molten iron from a blast furnace. Each kish graphite flake has a very stable nucleus, predominately manganese sulfide, which initiates cell formation at or near the liquidus temperature when molten cast iron solidifies.
