摘　　要：对不同氮含量下的含硼低碳贝氏体钢的强塑性、冲击韧性进行了对比分析,从微观组织简单分析了氮对钢板强度造成影响的原因,并从热力学角度解释了加钛固氮的必要性,针对冶炼过程中氮含量的控制提出了一系列措施。The mechanical properties of low carbon bainitic steel with different nitrogen content are studied. The reason for the effect of nitrogen on the strength of the steel plate is analyzed from its microstructure,and the necessity of adding titanium to nitrogen fixation is explained from the point of view of thermodynamics,and a series of measures are put forward to control nitrogen content in the smelting process.

关 键 词：氮含量 平衡热力学 脱氮
