Comparative analysis of advantages and disadvantages of electric arc furnace steelmaking and converter steelmaking in converter!


Electric arc furnace steelmaking is the main steelmaking method now. Of course, it is not all. Now some steelmaking methods are converters. Next, let's talk about the comparative analysis of the advantages and disadvantages of electric arc furnace steelmaking and converter steelmaking!


Advantages: high precipitation purity, short smelting cycle and low power consumption. As mentioned above, the converter takes the molten iron produced by the blast furnace as the main raw material, and the converter steelmaking steel has high purity and less impurity alloy elements. The converter steelmaking process completely depends on the chemical heat and physical heat caused by hot metal oxidation. There is no external energy input and the power consumption is low. The smelting cycle is 20 ~ 30 minutes. The smelting cycle of electric furnace steelmaking is short and the production rhythm is fast.


Disadvantages: low furnace temperature, not suitable for alloy elements that are difficult to dissolve, large furnace capacity and poor process flexibility. The converter steelmaking process completely depends on the chemical heat and physical heat generated by molten iron oxidation, and there is no external energy input. Therefore, the converter temperature is usually below 2000, which is not suitable for smelting alloy elements that are difficult to melt. The large-scale converter can usually reach more than 200 tons, but the larger furnace capacity is also the converter. The scale of furnace steel is large and the smelting flexibility is poor, so it is not suitable for smelting a small number of steel grades.
