Calculation model for turnover number of multifunctional hot metal ladle was proposed based on comprehensive consideration of ladle preparation and ladle allocation method for blast furnace. Ladle number was composed of three parts which were loaded ladle number for processing needs, required preparation and unloaded ladle number for excessive allocated for blast furnace. Ladle turnover number in 2 blast furnace?2 basic oxygen furnace production mode in Chongqing steel plant was obtained as 16 by applying the model. The results showed that decreasing the buffer capacity of loaded and unloaded ladle should be a crucial step to reduce the ladle turnover number. Therefore optimizing ladle allocation method and continuous casting heats were supposed to be adopted as feasible measures. Individual optimization of ladle allocation method and casting heats can both contribute to the decrease of 2 in ladle number. In addition, ladle number can be reduced by 4 with joint optimization according to the model.
