摘要
以S炼钢厂钢包为研究对象,解析钢包周转模式和不同钢水精炼工艺的周转周期;运用甘特图模拟出1台连铸机浇注时的钢包周转甘特图并分析其钢包运行特点,提出单浇次的钢包数量计算模型和周转率计算模型;模拟出3台连铸机同时浇注重叠时间大于钢包周转周期甘特图,研究重叠时间分别大于、介于和小于各连铸机钢包周转周期的钢包互用特点。研究结果表明:当先停浇的连铸机在浇次重叠时间内浇注的钢包数小于周转钢包数时,可有效减少钢包周转数量和提高钢包周转率,最终提出不同重叠时间条件下的钢包数量计算模型和周转率计算模型。
The S steelwork’s steel ladle was taken as the research object, and its operation mode and turnover cycle of various liquid steel refining process were analyzed. Through drawing out steel ladle’s turnover Gantt chart of single continuous caster and analyzing steel ladle’s operation characteristics, calculation model of turnover number and rotation ratio of single continuous caster was put forward. Through drawing out steel ladle’s turnover Gantt chart of 3 continuous casters and analyzing mixed use characteristics of cast overlap time greater than, less than, and in between turnover cycle of 3 continuous casters’ steel ladle, the operational control model of steel ladle was put forward. The results show that the model can effectively reduce the amount of steel ladle’s turnover number and raise steel ladle’s rotation ratio when CC’s casting heat number is less than turnover number of CC’s steel ladle during the overlap time.
