超纯铁素体不锈钢精炼过程中的脱氮

分析了超纯铁素体不钢精炼过程中影响深脱氮的因素，指出在低碳范围内深脱氮主要决定于钢液气钢界面积、钢液搅拌强度和气相中的氮分压。ＳＳ－ＶＯＤ、ＶＯＤ－ＰＢ、ＶＣＲ法是精炼超纯铁素体不锈钢的有效方法。     

Ultra-Pure Ferritic Stainless Steels-Grade,Refining Operation,and Application

The grades of ultra-pure ferritic stainless steels,especially the grades used in automobile exhaust system,were reviewed.The dependence of properties on alloying elements,the refining facilities,and the mechanism of the reactions in steel melts were described in detail.Vacuum,strong stirring,and powder injection proved to be effective technologies in the melting of ultra-pure ferritic stainless steels.The application of the ferritic grades was also briefly introduced.
