The shortage of coking coal and environmental pollution can be solved by oxygen enrichment top-blown smelting reduction ironmaking technology. The system energy efficiency is an important parameter. In order to further explore the energy saving potential of the system,based on the concept of exergy and the first and second law of thermodynamics,exergy analysis and the exergy analysis model is established,the exergy efficiency and the exergy loss in the system of ironmaking is analyzed and the direction and path of energy conservation are described. The results show that the exergy efficiency value is 91.36% and the main exergy loss is internal and external.According to different energy loss,we put forward specific energysaving measures.
