Abstract

A process for producing spheroidal graphite cast iron includes a spheroidization treatment, an inoculant treatment and a pouring inoculation treatment. A molten iron is subjected to the spheroidization treatment using a spheroidizing agent of an Fe—Si—Mg—Ca-based alloy which contains a given amount of Ba and contains substantially no rare-earth element.
