Abstract:
For further research on the precondition and the influence factors of ladle interaction among continuous casters, we took steel ladle of H steelmaking plant as the research object and analyzed the operation process and time of steel ladles. The relationship among turnover times, turnover numbers and cast numbers were analyzed. And the steel ladle's turnover process of 2 continuous casters with overlapping time of 50 min was simulated with Gantt chart. The simulation results show that the precondition of steel ladle interaction is the steel ladle no longer undertakes the transport task at 2# continuous caster and the empty ladle's ending time is prior to heavy ladle's starting time of 1# continuous caster. After researching the influence of overlapping time on ladle interaction, it's concluded that the precondition of steel ladle interaction is the cast number during overlapping time is less than the turnover number of steel ladle. By researching the influence of turnover cycle and casting time of single ladle on ladle interaction, it's showed the rational control and matching can raise the non-turnover number and probability of steel ladle interaction.
