Abstract
A method of producing spheroidal graphite cast iron in which the molten cast iron is passed over a nodularizing agent contained in a shallow depression in the bottom of a relatively wide, shallow flow channel. The nodularizing agent is dissolved at the interface between the molten cast iron and nodularizing agent, and the molten cast iron is passed over the nodularizing agent at a rate sufficient to scrub away the minor quantity of vapor produced so that the contact between the solid nodularizing agent and molten cast iron is not interrupted.
