| description | An object of the present invention is to provide spheroidal graphite cast iron having high properties using a spheroidizing agent containing no rare-earth element. The present invention relates to a method for producing spheroidal graphite cast iron having a specific final composition by subjecting a molten iron to a spheroidization treatment using a spheroidizing agent of an Fe-Si-Mg-Ca-based alloy containing no rare earth element and conducting an inoculation treatment using a first Fe-Si-based inoculant, and then conducting a pouring inoculation treatment with a given amount of a second Fe-Si-based inoculant containing 45 to 75% of Si, 1 to 3% of Ca, and 15 ppm or less of Ba. |
