Comparison of advantages and disadvantages between electric arc furnace and converter steelmaking!


There are great differences between electric arc furnace and converter steelmaking in raw materials, furnace temperature, smelting cycle and single furnace scale. I have nothing to do today. I'll give you a good introduction to the comparative analysis of the advantages and disadvantages of electric arc furnace and converter steelmaking!


Advantages: the second utilization of scrap alloy elements, the arc high temperature can dissolve the alloy elements that are difficult to dissolve, and accurately adjust the temperature in the furnace. In other words, electric arc furnace steelmaking uses waste materials. The elements in waste steel, especially alloy elements, can be used for many times in electric arc furnace steelmaking. Electric arc furnace uses the heat of electric arc between graphite electrode and iron material to smelt steel. The temperature of electric arc zone is up to 3000 degrees, which can smelt alloy elements that are difficult to melt in electric arc furnace. At the same time, it can accurately adjust the current and control the temperature in the furnace. The electric arc furnace can accurately adjust the molten steel temperature for a long time. The electric furnace has strong process flexibility and can meet the needs of smelting a variety of special steels.


Disadvantages: the quality of steel is greatly affected by scrap steel, long smelting cycle and large power consumption. In other words, the electric furnace takes scrap steel as the main raw material, which will absorb more impurities into precipitation in the smelting process, resulting in low precipitation quality. It is understood that the average tapping time of the new electric arc furnace widely used at present is 55 ~ 60 minutes, and the smelting cycle is longer than that of converter steelmaking. The power consumption is 500 kwh / T, which puts great pressure on the power supply pressure of the local power grid.


Well, the above is the analysis and comparison of the advantages and disadvantages of electric arc furnace steelmaking in terms of power consumption.
