Estimation of the parameters of preliminary deoxidation of an intermediate product from electro arc furnace (EAF) in the production of extralow-carbon steel

When smelting such grades of steels in EAF, aluminum is used to remove the over-oxidation of the metal, the amount of which must be consistent with the level of over-oxidation of metal. A thermodynamic assessment of the process of preliminary deoxidation of the intermediate product from EAF was carried out and a comparison was made with production data, the results of which showed the inconsistency of the fl ow rate required and given in the fl ow chart. In case of overconsumption of aluminum, the potential for removing carbon during vacuumisation decreases and the formation of alumina nonmetallic inclusions increases, and in case of a shortage of it, excessive loss of silicomanganese occurs.
