| 简介 |
The purpose of the present invention is to provide : a process for producing a spheroidal-graphite cast iron having high properties using a spheroidizing agent that contains no rare-earth element; and a spheroidal-graphite cast iron member comprising the spheroidal-graphite cast iron. The invention relates to obtaining a spheroidal-graphite cast iron having high properties and a spheroidal-graphite cast iron member by subjecting an iron melt to a spheroidization treatment with a spheroidizing agent comprising an Fe-Si-Mg-Ca alloy that contains a given amount of barium and contains substantially no rare-earth element, a first inoculation treatment, and a melt-stream inoculation treatment. |
