摘要
目前炼钢厂普遍存在转炉与连铸机生产节奏不匹配的现象,需要进行攒包生产才能保证连铸机连浇,因此,提出科学合理的钢包攒包生产控制模型对炼钢厂进一步实现节能降耗意义重大。以C炼钢厂钢包为研究对象,解析其运行模式和运行时间,分析转炉与连铸机匹配模式;通过分析钢包攒包时间与连铸机浇注炉次数之间的关系,构建钢包攒包生产运行时间控制模型,计算出合理的钢包攒包时间、重包运行时间和周转周期;运用甘特图分析法研究攒包生产条件下的钢包周转规律,构建钢包周转数量控制模型。将模型运用于实际,可有效减少钢包攒包数和周转数,提高周转率并减少钢水温降。
At present steel workshops exists the rhythm of production between converter and continuous caster does not match phenomenon,which need to saving ladle production to ensure the caster casting, therefore the scientific-reasonable saving ladle＇s control model of steel making plant could achieve energy saving significance. Based on the C steel workshop＇ s steel ladles as the research object, this article analyzes its operation mode and time, converter and caster matching model. Through analyzing the relationship between the time of saving ladle and the number of continuous caster＇s heats , the oper ating time control model of steel ladle＇s saving ladle is constructed, which could calculates the reasonable value of saving ladle＇s time, heavy ladle＇s operation time and steel ladle＇s turnover cycle. Through applying Gantt chart to analysis and study the turnover rule of saving ladle, the turnover number control model of steel ladle is constructed also. Satisfactory effects were obtained after applying the control model in production：saving number and turnover number were reduced, turnover ra- tio was increased and temperature drop was reduced.
