Abstract:The main material consumption indexes were gained by material and energy balance in the process of smelting steel and the concept of efficiency of smelting process and its calculation method was put forward. On this basis, the effect of change in price of scrap steel and scrap ratio on process efficiency and cost of per ton steel of converter and electric furnace had been calculated. Through the comparative analysis, the scrap steel prices range that high scrap ratio of converter smelting can improve the efficiency of the process and that electric furnace efficiency exceed that of converter were figured out. And the approximate scope of reasonable steel scrap ratio in converter and reasonable furnace hot metal ratio in electric furnace were also given.
