摘要
阐述了氮在不锈钢中利、害两方面作用。抚顺特殊钢股份有限公司采用EAF-AOD-LF-VD-MC电炉流程工艺生产低氮2Cr13管坯用不锈钢,研究得出过程中影响氮含量变化的关键因素,获得:冶炼结束后钢中含氮量小于80×10^(-6);浇注过程采用全封闭氩气保护,实现进氮量小于10×10^(-6),最终获得钢中氮含量小于100×10^(-6)的低氮2Cr13管坯用不锈钢。
The benefits and harms of nitrogen in stainless steel are described.A steel company uses eAF-AOD-LF-VD-MC electric furnace process to produce stainless steel for low nitrogen 2 Cr13 tube billet.The key factors affecting the change of nitrogen content in the process are studied and obtained:nitrogen content in steel is less than 80×10^(-6) after smelting.The casting process is protected by fully enclosed argon gas to achieve nitrogen intake less than 10×10^(-6).Finally,the low nitrogen 2 Cr13 pipe billet stainless steel with nitrogen content less than 100×10^(-6) is obtained.
