Production process of stainless steel
1. Smelting process of crude stainless steel The smelting process of stainless steel in the world today is mainly divided into one-step method, two-step method and three-step method, as well as new integrated production methods.
One-step smelting: molten iron + AOD (hydrogen smelting furnace);
two-step smelting: EAF (electric arc furnace) + AOD (hydrogen smelting furnace);
three-step smelting: EAF (electric arc furnace) + AOD (hydrogen refining furnace) + VOD (Vacuum Refining Furnace);
In addition to several traditional production processes, the new integrated production process, that is, the production process from molten iron to stainless steel, is adopted by many enterprises. The production process is: RKEF (rotary kiln) + AOD ( Hydrogen Refining Furnace)
