摘　　要：随着汽车板、管线钢的批量生产,对钢中氮含量的要求越来越高,通过炼钢转炉生产实践,分析终点氧、补吹、全程复吹、钢包包况、底吹氩控制、脱氧合金化、降温料加入量对钢中氮的影响,找到转炉生产过程中控制钢中氮的工艺措施,降低了钢中氮的含量,极大地提高了钢水的质量。With the mass production of car panels and linepipe steel, the nitrogen content in the steel is increasingly demanded. Briefed in the paper through the production of converter steel-making practice, analysis of the oxygen activity of the steel, second-blowing, blowing the whole complex, ladles situation Argon-blowing controling, deoxidation and alloying, the temperature reduction material addition and so on are expected to influence nitrogen content in steel, to find a process to control nitrogen in the converter steel, reducing the nitrogen content in steel has greatly improved the quality of molten steel.
