本发明公开了一种降低转炉终点金属熔池游离氧含量的方法，属于冶金技术领域，解决了现有技术中转炉终点金属熔池游离氧含量过高不能达到钢水清洁冶炼的问题。一种降低转炉终点金属熔池游离氧含量的方法，通过控制底吹供气元件供气、控制转炉终点顶吹供氧量和控制底吹与顶吹供气配合的复吹，实现了增加金属熔池碳氧反应界面和降低金属熔池内CO分压，降低游离氧含量。

The invention discloses a method for reducing the free oxygen content of the molten pool at the end of the converter, belonging to the metallurgical technology field, and solves the problem that the free oxygen content of the molten pool at the end of the converter in the existing technology is too high to reach the clean smelting of molten steel. A method to reduce the free oxygen content in the metal bath at the end of the converter is proposed. By controlling the gas supply of the bottom blowing gas supply component, the oxygen supply of the top blowing at the end of the converter and the combined blowing of the bottom blowing and the top blowing, the carbon-oxygen reaction interface in the metal bath is increased, the CO partial pressure in the metal bath is reduced, and the free oxygen content is reduced.
