摘　　要：为了探索并制定合理的钢铁制造流程炼铁-炼钢区段的生产系统结构和生产组织方式,介绍了钢铁制造流程炼铁-炼钢区段的界面模式、工序设备和动态运行过程,并采用离散事件动态系统相关理论对炼铁-炼钢区段动态运行过程进行了系统分析,提出了基于实体流图法和事件调度法的炼铁-炼钢区段动态运行过程的仿真模型和仿真策略。对某钢铁企业炼铁-炼钢区段动态运行过程进行了建模和仿真研究,结果表明,该企业炼铁-炼钢区段应采用"一罐一送"的铁水罐运输组织方式,此时3台机车利用最充分,平均作业率为60%,KR脱硫站进站铁水温度较高,且温度波动较小,KR脱硫站进站铁水温度平均值为1 423℃,极差为22℃。To explore and formulate the proper systematic structure and production organization of the ironmakingsteelmaking section in steel manufactory process,the interface mode,procedure equipment and operation process of ironmaking-steelmaking section were introduced.System analysis of the dynamic operation of ironmaking-steelmaking section was conducted according to the theories of discrete event dynamic system,and the simulation model and strategy based on the entity flow chart and events scheduling were put forward.A modeling and simulation pilot of the dynamic operation process of ironmaking-steelmaking section in a steel plant was carried out,the results showed that hot metal ladles should be transported in the way of "1 ladle each time" so that the average utilization rate of 3 locomotives was relatively as high as 60%,the average hot metal temperature arriving at KR station would be increased to 1 423℃ and the fluctuation would be minimized to 22℃.
