PROCESS FOR PRODUCING SPHEROIDAL-GRAPHITE CAST IRON, AND SPHEROIDAL-GRAPHITE CAST IRON MEMBER OBTAINED FROM SAID SPHEROIDAL-GRAPHITE CAST IRON

摘要

Be designed to provide: for producing, with high property value spheroidal graphite cast iron nodularizer, that is free of rare earth element; It include spheroidal graphite cast-iron with a kind of spheroidal graphite cast-iron component. It include that a certain amount of barium contains substantially no rare earth element by including one kind with Fe-Si-Mg-Ca alloys to the processing of spheroidization molten iron nodulizer the present invention relates to spheroidal graphite cast-iron is obtained with high-mechanical property and spheroidal graphite cast-iron component, first inoculation is handled, by melt flow inoculation.
