钢包调度评价方法研究

Study on the Evaluation Method of Ladle Scheduling

针对以钢包周转个数为基础的钢包运行评价难以反映实际调度现状的问题,提出一种基于生产计划和钢包待用时间解析的钢包调度现状评价方法.首先,利用钢包运行过程中重包个数的波动表征生产计划对钢包运行情况的影响.然后,通过解析钢包待用时间,给出额外周转包个数和钢包调度离线率的计算方法,分别用以表征不同状态钢包的调度,并通过实际数据确定钢包调度现状的综合评定方法.最后,以实际生产数据对该评价方法进行验证.结果表明,该评价方法可以准确评价钢包调度现状,并可为生产实践提供相应的指导.

A newevaluation method of ladle scheduling status based on the production schedule and analysis on the interval stand-by time of ladle turnaround was proposed,due to the previous assessment on the basis of the number of turnaround ladle was difficult to reflect actual scheduling.Firstly,the influence of the production schedule on ladle running process was characterized by the fluctuation in the number of full package ladles. Then,the calculation method for the additional turnover package number and the offline ladle scheduling ratio was put forward through the analysis of ladle stand-by time,which was used to characterize ladle scheduling in different conditions,thus a comprehensive assessment method adopting practice production data was raised.Finally,the evaluation method was verified by the actual production data. The results showthat the evaluation method can accurately evaluate the overall status of ladle scheduling and can provide guidance for the practice production process.
