In the recent decade,the remarkable achievements have been made on steelmaking technology with electric arc furnace(EAF)in China,on the basis of importing and assimilating new technologies from abroad and making innovation.The integrated control theory of tap-totap time and electric power consumption of modern EAF was put forward and hence showed the research direction to shorten tap-to-tap time,decrease electric energy consumption and increase productivity and the basis to select rated power of transformer.EAF steelmaking technology with hot metal charging,terminal point control(TPC)technology,bottom blowing technology with nitrogen instead of argon and low nitrogen steel producing technology were obtained.Finally,the structure model of raw materials was presented.
