冶炼J55钢过程氮控制及工艺优化

Nitrogen Control and Process Optimization of J55 Steel Smelting Process

论述了J55石油套管用钢在炼钢工序的不同环节,工艺控制对钢中氮含量的决定性作用。指出生产低硫、低氮钢的限制性环节,制定了相应的工艺改进措施。

This paper discusses the different segments of the J55 oil tube steel in the steelmaking process, process con- trol a decisive role in the nitrogen content in the steel. Pointed out that the restrictive aspects of the production of low-sulfur low-nitrogen steel, the development of process improvement measures.
