Abstract
Steel ladle is the indispensable vessel of transporting and refining molten steel. In order to realize efficient control of steel ladle and optimize the production organization of steelworks, the operational control model of steel ladles should be proposed. Based on steel ladles of Z steelwork as the research object, operation mode and turnover cycle of steel ladle were analyzed. Through drawing out steel ladle Gantt chart of single continuous caster and analyzing operation characteristics of steel ladle, calculation model of turnover number and rotation ratio of single continuous caster was put forward. Through drawing out steel ladle turnover Gantt chart of 3 continuous casters and analyzing mixed use characteristics of cast overlap time greater than, less than, and in between steel ladle turnover cycle of 3 continuous casters, the operational control model of steel ladles was put forward. Researches show that the model can effectively reduce amount of steel ladle turnover number and raise steel ladle rotation ratio when casting heat number of CC is less than steel ladle turnover number during the overlap time.
