摘要
简述了某炼钢厂将转炉冶炼的齿轮钢钢水倒运到电炉车间进行精炼的工艺管控过程。包括转炉的脱磷和挡渣操作,精炼炉的送电制度,钙处理等影响质量的关键控制环节。同时也对轧制工艺进行改进,采用控轧控冷的TMCP技术,使圆钢轧材质量更加稳定。
The process management during the transportation of molten steel for gear steel production from BOF to electric furnace shop for further refining in the No.2 plant of a steel and iron company is briefly discussed.The dephosphorus and slag stopping in BOF,and the electricity delivery and calcium disposal in LF,important procedures affecting product quality,are included in the paper.Meanwhile the rolling process is also improved,and the advanced TMCP technique of controlled rolling and controlled cooling（CRCC technology） is adopted.Thus,rolled products with more consistent quality are obtained.
