The research on material flow, energy flow and the relationship between them will benefit the construction of a resource saving and environmentally friendly enterprise. Recently, more and more researchers are paying their attentions to the study of material flow and energy flow of iron and steel enterprise. The modern iron & steel joint enterprise is a complicated iron-coal chemical system, and the steel production process is, in essence, the dynamic operation of the materials flow under the drive and effect from energy flow following the definite rules (Yin, 2000, 2007, 2008). Lu proposed the e-p analysis method (Lu et al., 2000) and the standard material flow diagram for blast furnace – converter process (Dai & Lu, 2004) which is used to analyze the Fe resource efficiency. Based on the standard process energy consumption, the influence of material flow of iron and steel enterprise on its energy consumption was studied (Chen et al., 2002). The relationship between materials flow and energy flow was established (Cai et al., 2006) and they were expressed by the item of energy consumption per ton of steel (Cai et al., 2008).
