Abstract

A lot of energy resources such as coal, electricity and oils, are consumed during the steel production, and simultaneously a variety of waste heat and energy is produced. If most of the waste heat and energy can be recovered by the self-supply power plant and other generating devices, then the electricity consumed by the factory can be supplied by itself, which can be called the “autarky mode of electricity”. The autarky mode of electricity can improve the recovery of the waste heat and energy, and thus reduce the energy consumption of an iron & steel factory. Based on the BF-BOF steelmaking routes, the energy-flow models for the electricity generating with waste heat and energy are constructed. The autarky modes of electricity of the factories with different production scales are put forward, and the contribution of the mode to energy saving and economic benefits is analyzed.
