| Abstract: | The effect of all kinds of technique on controlling Nitrogen and Oxygen content in liquid steel to lower level is explained. This paper points out: Nitrogen content in liquid steel can be efficiently reduced after adopting foamed slag in LF and using protective measurements while casting, adopting slag washing technique in LF and controlling casting temperature of liquid steel can obviously reduce oxygen content. |
