Abstract: Steel ladles of Kunsteel Steelmaking Works were taken as the object of research, for the further optimization of steel ladle interaction among continuous caster in steelmaking works. The relationship among cast number, the turnover number, turnover times and last turnover number are further analyzed, which is build on the basis of revolving quantity calculation model of single cast steel ladle. Then, the simulation of steel ladle turnover rules was taken on the 2 continuous casters with Gantt chart. After that, the relationships of turnover number and last turnover number and non-turnover number are researched deeply. Combining with the Gantt chart, the expressions of start casting time, empty ladle ending time and heavy ladle starting time were put forward. Finally, the precondition of steel ladle interaction was obtained, which meant the steel ladle no longer undertake the transport task at first stop continuous caster and the exchange ladle’s turnover ending time was prior to ladle’s turnover starting time of last start casting continuous caster. Studies have shown that the steel ladles of steelmaking works can be reduced from 13 to 10.
