为优化炼钢厂多台连铸机间钢包配置,以昆钢炼钢厂钢包为研究对象,在已有单浇次钢包周转数量计算模型基础上,进一步分析了浇铸炉次数与钢包周转数、周转次数、最后周转数之间的关系。运用甘特图对2台连铸机钢包周转规律进行模拟,分析了钢包周转数与1浇次最后需要周转的钢包数、不需要周转的钢包数之间的对应关系。结合甘特图提出各炉次钢包开始浇铸时间、空包结束时间和重包开始时间表达式。最终得出实现2台连铸机间钢包互用的前提条件:用于交换的钢包在先停浇连铸机不再承担运输任务,且此钢包的周转结束时间应早于后开浇连铸机钢包的周转开始时间。研究表明:昆钢炼钢厂钢包配置数可由原来的13个减少为10个。
In order to optimize the ladle configuration of multiple continuous casting machines in steel mills, taking ladle as the research object in Kunming Iron and Steel Plant, based on the calculation model of the number of single ladle turnover, the number of casting furnaces and ladle turnover were further analyzed, The number of turnover, the relationship between the last turnover. Gantt chart was used to simulate the ladle turnover rule of two caster, the relationship between the number of ladle revolutions and the ladle number that need to be revolved at last, and the number of ladle which does not need revolving was analyzed. According to the Gantt chart, the expression of ladle start casting time, empty package end time and heavy package start time were put forward. The final result is that the two ladle ladle to achieve interoperability between preconditions: the ladle for exchange in the first stop pouring caster no longer bear the task of transportation, and the ladle turnaround time should be earlier than after open casting Machine ladle turnaround start time. The research shows that the number of ladles in Kunming Iron and Steel Works can be reduced from 13 to 10.
