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 automotive and pipeline steel, the requirements on the nitrogen content in steel are getting higher and higher. Through the practice of steelmaking converter production, analysis of the terminal oxygen, make-up, full blown, steel bag, bottom blown argon control, Deoxidization alloying, the amount of cooling material on the amount of nitrogen in the steel to find the converter during the production of nitrogen in steel control measures to reduce the nitrogen content of steel, which greatly improves the quality of molten steel.
