Abstract：Based on the characteristics of the steel manufacturing process, the necessity and connotation of interface technology are described. Material flow optimization and interface function matching integration of the "interface" of ironmaking-steelmaking, steelmaking-continuous casting, and continuous casting-hot rolling are important for reducing energy consumption, material consumption, cost reduction, and environmental protection so as to attract the attention of steel industry practitioners, especially managers. The residual energy and energy loss of a rod and wire mill with an annual output of 2.9×106 t are calculated. The energy loss of difference interfaces under different conditions are also analyzed in this paper. Finally, it is pointed out that optimization of the molten iron transportation, ladle turnover, and billets transportation is the key to reduce the energy loss in the process. In addition, the development of waste heat recovery technology for rolled products at the end of hot rolling should be paid attention to.
