分析了连铸--热轧区段混装一体化生产和加热炉群生产模式,并在此基础上建立了混装一体化生产下加热炉群调度模型.模型在满足加热炉生产工艺的基础上充分考虑了板坯进入加热炉前的等待时间和轧机空闲时间.采用禁忌搜索算法对模型进行了求解.最后,针对大批量少品种和小批量多品种两组板坯对某钢厂1580mm轧线非专用炉模式与专用炉模式分别进行了仿真.仿真结果表明连铸--热轧区段采用专用炉模式生产比传统的非专用炉模式生产能够明显提高加热炉热效率.

The integrated production of mixed casting and hot rolling section and the production mode of heating furnace group were analyzed, and on the basis of that, a scheduling model of heating furnace group under integrated production was established. The model can meet the requirements of heating furnace production process Fully considering the waiting time before the slab enters the heating furnace and the idle time of the rolling mill.The tabu search algorithm is used to solve the model.Finally, according to the slab size of two large slabs of small batch and small batch, Line non-dedicated furnace mode and special furnace mode respectively.The simulation results show that the use of special furnace mode for the continuous casting and hot-rolling sections can obviously improve the thermal efficiency of the heating furnace compared with the traditional non-special furnace mode.
