Abstract：Iron and steel industry not only consume large amounts of water but emit more wastewater，it’s imperative to save water and reduce emission. Water flow model in iron and steel industry was built with the following observation model of SFA（substance flow analysis），and the composition of comprehensive water consumption per ton steel was analyzed by the current model. Based on the theory of Systems Energy Conservation，the[w-p]mathematics model of comprehensive water consumption in a steel enterprise was established，and this study proposed the[w-p]analytical method to dissect the comprehensive water consumption. An iron and steel enterprise in China was taken as an example to analyze the influence of the change of process water consumption and steel ratio on the water consumption per ton steel. The results indicated that reducing the process water consumption of each process is a major influence to lower the water consumption per ton steel，and it also pointed that reducing process water consumption was the main research trend to reduce emissions and save water resources along with the structure adjustment and technology improvement. The direction and measures of reducing the comprehensive water consumption per ton steel were obtained through the model analysis and case study.
