针对某不锈钢和碳钢的混合型板带钢厂,分析了板坯连铸-轧钢各个关键工序的出坯节奏和年产能力,得出非专用加热炉最优配置数量为3座;为了实现板坯连铸-轧钢工序的协同、高效运行,研究了加热炉群的调度问题,运用改进的遗传算法对加热炉群调度模型进行求解,得出优化的调度方案。研究结果表明:通过对加热炉工序的配置与加热炉群调度优化进行综合研究,得到单块板坯在加热炉外的平均等待时间可减少20min以上,热送热装率提高8%以上。
For a mixed strip steel mill of stainless steel and carbon steel, the basting tempo and annual output capacity of each key process of slab continuous casting and rolling are analyzed. The optimal number of non-special heating furnaces is 3. In order to achieve Slab continuous casting and rolling process work synergistically and efficiently. The scheduling problem of reheating furnace group is studied. An improved genetic algorithm is used to solve the scheduling model of reheating furnace group. The optimal scheduling scheme is obtained. The results show that the average waiting time outside the heating furnace can be reduced by more than 20 minutes and the heat transfer rate can be increased more than 8% by comprehensively studying the configuration of heating furnace and the scheduling optimization of heating furnace group.
