This paper studies the coupling model of material flow and energy flow in the production process of lead smelting enterprises, and establishes the mathematical model for material flow and energy flow to resolve optimization problems. From the point of energy flow, the paper analyses three kinds of energy flow change which effect on the enterprise products. Through calculation and analysis, there is 38.42% energy- saving potential in this enterprise. Separately from the material flow and energy flow angle, the paper puts forward five aspects suggestions to reduce the energy consumption of enterprise products.
