<p>The top–bottom combined blowing converter mainly adopts the blowing method of top-blowing oxygen and bottom-blowing nitrogen. In the production process, there are some disadvantages, such as a significant temperature difference between the top and bottom of the molten pool, inadequate gas permeability of bottom blowing, and low decarburization efficiency. Therefore, we propose a novel bottom-blowing gas doped oxygen process to enhance the smelting conditions in the converter. The 500&#xa0;kg medium frequency induction furnace with top and bottom-blowing function was used to explore the influence of the proportion of bottom-blowing gas doped oxygen on the smelting effect in different smelting cycles. Subsequently, industrial experimental verification was carried out on a 60 t converter. The results of intermediate frequency furnace experiments demonstrate that the bottom-blowing gas doped oxygen process exhibits a superior heating rate and decarburization efficiency during the initial and final stages of blowing compared to pure N₂ used for bottom-blowing. Simultaneously, the dephosphorization efficiency exhibited an initial increase followed by a subsequent decrease as the bottom-blowing oxygen content increased. The industrial test of 60 t converter validates the findings above. Moreover, when the oxygen content in bottom-blowing gas is 5%, the average blowing time reduces by 54&#xa0;s, and the minimum endpoint carbon–oxygen equilibrium reaches 0.00219 under this condition. The results demonstrate that the appropriate amount of oxygen doped in bottom-blowing gas can effectively enhance the metallurgical conditions of the converter and improve production efficiency.</p>
