This application discloses a method for reducing the final carbon-oxygen product and final slag TFe in a converter, relating to the field of metallurgical steelmaking technology. This method employs a staged oxygen supply mode, effectively improving oxygen utilization, enhancing decarburization efficiency, and reducing over-oxidation in the molten pool during the later stages of smelting. This brings the carbon-oxygen reaction in the final steel closer to equilibrium, thereby significantly reducing the final carbon-oxygen product, decreasing deoxidizer consumption, and increasing metal yield. The method utilizes a charging strategy of "concentrated charging in the early stage, batch supplementary charging in the middle and later stages, and cessation of ore charging in the later stage." This strategy ensures dephosphorization by adding lime and ore in the early stage and reduces iron oxidation loss by strictly limiting the amount of ore added in the later stages, resulting in a significant reduction in FeO content in the final slag, i.e., a significant decrease in final slag TFe. This directly reduces steelmaking material consumption and mitigates slag erosion of the furnace lining, thus extending the converter's service life.
