Abstract It starts from the nature and the physical essence of the dynamic operation of the steel manufacturing process. The behavior rules of ferruginous flow and energy flow is described，and the mechanism of energy conversion in the steel manufacturing processes is also described. It is concluded that the energy conversion process is inevitably accompanied by the energy dissipation，so the energy conversion time should be minimized. It is pointed out that in the steel manufacturing process，the ferruginous flow is accompanied by the energy flow，but the energy flow some-times operates with ferruginous flow，sometimes operates separately. A rod and wire mill with the annual output of 2.9 million tons is constructed. The recovery and utilization of the residual energy of this process are calculated according to the main production processes. The energy efficiency of this process is also analyzed. Finally，it is point out that improving the recovery rate of the residual energy and constructing an energy control center with the synergistically optimized energy flow network and material flow network are important ways to improve the energy efficiency of the whole steel enterprise.
