Abstract

PURPOSE: To melt and make the steel containing low hydrogen and nitrogen in solid solution state by conbining the effective O2 concentration more than the specified value in oxidizing agent of mill scale etc. so as to suppress the carbon concn. in molten steel bath at melt down to the low value and by blowing carbon into this molten steel to the aimed concn. by carrier gas.
