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.
