We all know that=“ http://www.ayynd.com/product/20 The main raw material for electric arc furnace steelmaking is scrap steel, but currently, scrap steel resources are relatively scarce, which poses a certain obstacle to the development of electric arc furnace steelmaking. In order to solve this problem, we must find substitutes for electric arc furnace steelmaking raw materials. Currently, the main substitutes that can replace electric arc furnace steelmaking include molten iron, decarburized granular iron, carbide iron, composite metal materials, etc. Today we will have a detailed understanding of this molten iron:
If molten iron is used in electric arc furnace steelmaking, there are many advantages, please refer to the following text:
1. For non flat melt pool smelting furnaces, power supply can be optimized, molten pool can be formed in advance, high-power power supply time can be increased, and smelting cycle can be shortened;
;
　　2、 Increase physical and chemical heat to improve thermal efficiency;
　　3、 It can dilute the content of harmful metal impurities in the molten steel. Of course, the more iron added, the better. It is more appropriate to control the iron to liquid ratio at 30% -50%. When the oxygen supply intensity is low, the optimal ratio of molten iron is about 30%; When the oxygen supply intensity is high, the ratio of molten iron can reach 50%. The Quantum electric arc furnace developed by German company Pruitt proposes that at least 50% of scrap steel should be used to achieve sufficient preheating efficiency. The converter smelting method of all iron hydroelectric furnaces has caused electric arc furnaces to lose their superiority in sustainable development. Alright, the above is the main analysis of raw materials for electric arc furnace smelting.
