摘　　要：文章研究了不同转炉底吹模式下同一钢种以及相同转炉底吹模式下不同钢种中的氮含量变化规律,同时研究了转炉工艺参数、钢水成分及温度对转炉终点钢中氮含量的影响,对实际生产中氮含量控制具有一定的指导意义。In this paper,it is researched the variational rules of nitrogen content in the same steel grade with different bottom blowing modes of converter and that in different steel grades with the same bottom blowing mode of converter.Meanwhile,the effects of technological parameters of converter,components and temperature of liquid steel on nitrogen content in terminal steel of converter are studied,which could be as the guidance for controlling nitrogen content in actual production.
