Zusammenfassung:PROBLEM TO BE SOLVED: To easily control the content of S in cast iron without the addition of a vulcanizing material in the production of cast iron by electric furnace dissolution. SOLUTION: The raw material pig is obtained by adding a vulcanizing material such as iron sulfide to a hot metal extracted from a blast furnace at least in either one place from a hot metal gutter to a tundish before a pig iron casting machine to increase the content of S in the hot metal, and thereafter performing cooling/solidifying by the pig iron casting machine, and comprises, by mass, 3.0 to 4.5% C, 0.1 to 12% Si, 0.01 to 5% Mn and >0.3 to 5% S, and the balance Fe with inevitable impurities.
