摘　　要：应用等离子氮弧冶炼不锈钢,研究了影响钢中氮合金元素的主要因素。主要研究等离子氮气流量、钢液搅拌强度、精炼时间等因素影响钢液增氮的规律。提高等离子氮流量、增强搅拌、延长精炼时间,钢中含氮量增加。Stainless steel was smelted with plasma arc torch. The main factors which affect the content of nitrogen alloying in the steel under plasma are investigated. The results show that increasing the nitrogen rate as plasma arc gas, higher stirring intensity and longer alloying time, the nitrogen content in steel is also increased.

关 键 词：等离子体氮弧 不锈钢 熔炼 合金化
