Abstract “One Ladle Technology” mode is more advanced operation mode in BF-BOF section. OLT，which has a significant advantage in area occupying，equipment investment，staffing and operation time，temperature drop of hot metal and dust emission compared with other models，has been gradually accepted and applied in steel production enterprises. Based on the case study of BF and BOF section “One Ladle Technology” in Shougang Jingtang，operation mode in time and HML turnover time，temperature drop of full HML and empty HML are analyzed. Based on the results，the dynamic operating rules for HML turnover are put forward which has achieved remarkable results in Shougang Jingtang.
