摘要： An object of the present invention is to provide a process for producing spheroidal graphite cast iron having high properties using a spheroidizing agent containing no rare-earth element and to provide a spheroidal graphite cast iron member including the spheroidal graphite cast iron.
The present invention relates to obtaining spheroidal graphite cast iron having high properties and a spheroidal graphite cast iron member by subjecting a molten iron to a 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 and to a primary inoculation treatment and a pouring inoculation treatment.摘要翻译： 本发明的一个目的是提供一种生产使用了球化剂不含有稀土类元素和以提供球状石墨铸铁构件包括球墨铸铁具有高性能的球状石墨铸铁的方法。 本发明涉及获得具有高特性，并通过使用-Fe基的Si镁钙合金制成的球化剂，其包含给定量进行铁水的球化处理一球状石墨铸铁构件球墨铸铁 的Ba和实质上不含有稀土类元素和以一个初级接种处理和浇注孕育处理。
