Abstract: On the basis of site investigation，some problems in the production of BOF steelmaking were found. 1）The ladle cranes were running at a full capacity in the middle & later stages of converter lining service，there was a potential hidden danger. 2）When the weight of liquid steel in ladle reached 120t，the space height above liquid steel in the ladle was between 200mm and 300mm，that was not satisfied with the requirement of ladle furnace (400—600mm).3）The life of the ladle lining was low，the consumption of lining was high，the labor intensity of workers was high.4）In the later stages of ladle lining service，the surface temperature of ladle approached creep temperature，there was also a potential hidden danger. Therefore，the following works were carried out，and some good results were got.1）By adjusting the refining slag composition and the alloy kinds and proportion， enhancing the quality of lining and masonry，the eroding rate of ladle lining was decreased from 2.5mm to 1.1mm at a heat，the life of ladle lining was raised from 67heats to 157heats.2）In order to ensure the height space above liquid steel in the ladle be satisfied with the refining requirement when the weight of liquid steel in ladle reached 120t，the thickness of working layers was cut down 30mm，the life of ladle lining was adjusted from 157 to 127 heats.3）Because of reducing thickness of work layers and adjusting the material of permanent layers，the weight of ladle lining was reduced 3.8t，the weight of ladle with lining & liquid steel was decreased from 180t to 176.2t，ladle cranes were safer.4）Because of permanent layer with the good thermal insulation property，the surface temperature of steel ladle was decreased form 280—292℃ to 252—262℃，the steel ladles were safer.5）After reform of refractory for liquid steel ladle，the consumption of the lining，alloys，refining slag，electrical power and electrode was significantly reduced，the producing cost was reduced 12.16yuan/t .
