摘　　要：铁前工序是钢铁工业能源消耗的主要环节,占总能耗的80%。为此,根据铁前工序的生产数据,通过建立物料平衡,建立了Exergy计算模型,获得了各工序的Exergy平衡关系、热力学完善度、Exergy效率、Exergy损失系数。同时结合理论分析,论述了Exergy分析法对铁前工序(焦化、烧结、高炉炼铁)节能分析的优势,并且提出各工序的节能途径。Ironmaking system is the main part of energy consumption in iron and steel industry , which account for 80%of the total energy consumption .So, it acquired Exergy balance , thermodynamics in-tegrity , Exergy efficiency and Exergy loss coefficient of each process through the establishment of Exer -gy calculation model and material balance which was based on the production data of ironmaking sys -tem.The advantage of Exergy analysis in ironmaking system （ coking, sintering, blast furnace ） was described .And the energy saving way of each process was put forwarded .
