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.

Abstract: The techno-interface of BF-BOF region is an important stage that connects iron making procedure with steel making procedure in the production line, acting as a connecting link between the preceding and the following procedure. It is also the key region to optimize the iron making and steel making process as a whole. In this paper, based on queuing theory method for BF-BOF region simulation, a static simulation method is presented to realize the simulation of dynamic system, WITNESS is used to simulate the M/M/1 queue model. The number of different transportation ladles has been analyzed to influence the BF-BOF region, the best ladles were obtained in order to improve production rate. The results show that the modeling method can reflect the complex system characteristics of BF-BOF region and provide the advice for system optimization.
