摘要： 论述了生产工艺发展、工艺流程结构变化及余热余能利用技术应用对钢厂能耗的影响，以及钢厂能耗分析与评价方法的研究进展. 指出基于物质流系统的能耗分析应注重主生产工序间物流状况及各工序的工艺改进，基于能量流系统的能耗分析更重视能量子系统间的能源供求匹配、能级匹配；钢铁产品生命周期分析将能耗研究范围扩展至钢铁生产过程的上、下游环节，有助于实现系统节能. 讨论了现有能耗评价基准(理论最小值、实际最小值、优化后最佳值、世界/区域最佳实践值)的优劣及其应用范围，并结合一般系统的可靠性，提出和探讨了钢厂能耗可靠性评价及其深入研究方向，以挖掘系统在原料条件、产品结构及维修制度、操作水平等方面的节能潜力，实现能耗的精细控制.

Abstract: Influential factors, such as development of process technology, evolution of manufacturing process structure, application of waste heat and energy recovery technology, on energy consumption in steel plants are summarized. Moreover, evolution of analysis and evaluation methods are reviewed, which indicates that analysis of energy consumption (AEC) based on mass flow system focuses on improvement of mass flow condition and each procedure process, while AEC based on energy flow system concentrates on matching of energy supply and demand, matching of energy-level between different energy subsystems. Meanwhile, the research scope on energy consumption has been extended to the upstream and downstream link of steel manufacturing process with life cycle analysis, which contributes to system energy saving. The advantages and disadvantages of current evaluation benchmark of energy consumption, including theoretical minimum value, actual minimum value, optimum value and world (region) best practice value, as well as field of their applications are discussed. Based on these, combined with reliability of general system, energy reliability assessment and its further research in steel plants are presented, which is used to explore the energy saving potential of raw material condition, product structure, maintenance system and operating level for precise control of energy consumption.

Key words: steel plant, energy consumption analysis, evaluation index, benchmark, reliability
