What are the advantages of electric arc furnace steelmaking?


As we all know, the raw material of electric arc furnace steelmaking is scrap steel. As we all know, such resources are relatively scarce, so it is necessary to find relatively alternative raw materials. At present, the better raw materials are iron carbide, molten iron, decarburized granular iron and composite metal materials. Xiaobian will introduce the advantages of molten iron to you today:

If molten iron is used for EAF steelmaking, see the following advantages:


1. For the smelting furnace with non flat bath, the power supply can be adjusted and optimized to form the bath in advance, increase the power supply time of high power and shorten the smelting cycle;


2. It can dilute harmful metal impurities in molten steel.


3. Increase physical heat and chemical heat to improve thermal efficiency;


Of course, the more molten iron, the better. It is more appropriate to control the molten iron ratio at 30% - 50%. When the oxygen supply intensity is relatively low, the proportion of molten iron is about 30%; When the oxygen supply intensity is high, the proportion of molten iron can reach 50%. In order to obtain good preheating benefits, the electric arc furnace developed by youngde recommends that scrap steel be used at least 50%. The converter smelting mode of all iron hydropower furnace makes the electric arc furnace lose its advantage in sustainable development.


OK, the above is about the advantages of EAF steelmaking. For more details, please refer to the official website: http://www.ayynd.com/
