专用炉模式下加热炉群混装一体化生产

Hybrid direct hot charge rolling production for specific reheating furnace mode

  • 摘要: 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.

     

    Abstract: The hybrid direct hot charge rolling (DHCR) production of continuous casting to hot rolling and the production mode of reheating furnaces were analyzed. A schedule model of reheating furnaces based on hybrid DHCR production was established. On the basis of meeting the requirements of the reheating furnace process, the model considers the waiting time before slabs entering the reheating furnaces and the idle time of the hot rolling mill. The Tabu search algorithm was used in the model. Finally, two slab groups, which are few varieties with large quantities and many varieties with small quantities, were simulated in a 1 580 mm hot rolling line for specific and non-specific reheating furnace modes. Simulation results show that the specific reheating furnace mode can significantly improve the thermal efficiency of reheating furnaces.
