Abstract: In order to promote the intelligent transformation and upgrading of the steel industry, intelligent technology features of the steel industrial are discussed in this paper, which are based on the present situation and existing problems of the steel industry. Based on the research situation abroad and domestic, Function analysis, reasonable positioning and process optimization approach of each process of steel making segment are expounded in this paper, at the same time the present situation of molten steel quality and implementation path under narrow window control are analysed, The idea of stability narrow window control technology of steel quality controlled by multi–factors including composition, temperature, time, cleanliness, consumption (raw material) is proposed, and it provides important guidance for the development of green and intelligent steel manufacturing process in the future.
