摘　　要：对含氮不锈钢的AOD炉冶炼工艺难点和高温热塑性进行了研究 ,得出含氮不锈钢用AOD炉冶炼完全采用氮气进行氮元素合金化工艺是可行的 ,用模型预测钢中氮含量 ,不经在线分析钢中氮含量 ,精度可达到± 0 0 15 % ;含氮不锈钢的高温热塑性主要受热加工温度、钢中硫含量、氮含量等因素影响。The difficulties of smelting process and hot ductility about nitrogen-contained stainless steel were studied. Results show nitrogen alloying of nitrogen-contained stainless steel by smelting in AOD is feasible. Without analysis on line, nitrogen content precision can be controlled in ±0.015?% with model prediction; The hot ductility is influenced by hot worked temperature, sulfur content, nitrogen content and so on.
