Considerations on Steel Manufacturing Process

Abstract

The comprehensive influence on the overall integration of steel manufacturing process is discussed in this paper, which influences not only the target group of technique and economy, but also the process emission and environment. The evolution of steel manufacturing process for a long period is reviewed, which can be summarized as from simplicity to complication and then from complication to simplification. It is pointed out that the essence of steel manufacturing process is a production system which is combined mass state transformation, mass property control and mass flow control. It is a multi-dimensional mass-flow control system. In fact, the optimization of steel manufacturing process is the analysis-optimization of the collection of procedure's function, the harmony optimization of the collection of procedure's relations and restructuring optimization of collection of procedures in the process. Based on above theory, the linkage optimization of function-structure-efficiency for steel plants will be realized and the mode of steel plants will be improved. It is proposed that the social/economic role of steel plants should be positioned actively. The function of manufacturing process at the steel plants should be evolved from metallurgical function mainly to a multifunctional, which has both energy conversion and environmental treatment of social wastage. The steel plants may be an important part of the ecological industry zone in the future.
