摘　　要：智能钢厂是实现绿色低碳钢铁制造目标和钢铁工业高质量发展的必然路径。冶金流程工程学的提出和发展,已成为指导钢铁业高质量可持续发展的重要理论基石。为了达成智能钢厂低碳高效的生产目标,实现资源/能源的优化配置,从冶金流程工程学提出的钢铁制造流程动态运行物理本质出发,开展制造流程“运行程序”相应的智能管控技术研发,力求通过生产计划调度技术实现对炼钢-连铸-热轧等制造流程的“运行程序”控制,以适应市场需求下订单驱动的钢铁制造模式,这是促使生产过程有序、高效低成本运行的调控手段,即生产计划调度指令决定了钢铁企业设备利用率、生产效率和能源利用效率。讨论了以生产计划调度为核心的钢铁制造流程的运行管控技术,并给出了实践案例,针对中厚板组板及板坯一体化设计问题,实现了生产订单的组合优化,有效提升了系统成材率,为规模化钢铁生产满足个性化多品种小批量市场需求创造了条件;一体化生产批量计划相比于分工序编制生产批量计划能够降低余材率1.27%,提升炼钢-连铸-热轧区段物质流运行管控效果;基于炼钢厂生产调度和动态调度的物质流运行优化,可以缩短生产流程总时间10%,降低转炉工序用氧波动49.32%,改善了物质流和能量流的协同运行效果。因此,通过生产计划调度的“运行程序”控制技术,引导制造流程系统朝着动态-有序、协同-连续的运行状态发展,进而有利于实现钢铁生产的高效低成本优化运行。Smart steel plants are an inevitable path to achieve the goal of green and low-carbon steel manufacturing and the high-quality development of steel industry.Metallurgical process engineering has become an important theoretical cornerstone for guiding the high-quality sustainable development of the steel industry.To achieve the goal of low-carbon and efficient production in intelligent steel plants and optimize resource/energy allocation,based on the physical essence of dynamic operation of steel manufacturing processes proposed in metallurgical process engineering,intelligent control technology research and development corresponding to the"operation program"of manufacturing processes are carried out.Strive to achieve"operation program"control of the steelmaking-continuous casting-hot rolling manufacturing process through production planning and scheduling technology,in order to adapt to the order driven steel manufacturing model under market demand.This is a regulatory means to promote the orderly,efficient and low-cost operation of the production process,that is,the production planning and scheduling instructions determine the level of equipment utilization,production efficiency,and energy utilization efficiency in steel enterprises.The operation and control technology and practice of steel manufacturing processes with production planning and scheduling as the core were discussed.Aiming at the integrated design of plate assembly and slab,combinatorial optimization of production orders is realized,which effectively improves the yield of the system and creates conditions for large-scale steel production to meet the market demand of personalized multi variety and small batch.Integrated production batch planning can reduce the residual material rate by 1.27%and improve the mass flow control effect in the steelmaking-continuous casting-hot rolling sections compared to the production batch planning based on separate processes.The optimization of mass flow operation based on production scheduling and dynamic scheduling
