摘　　要：通过对提钒转炉过程及终点炉渣进行系列分析，研究了提钒脱磷过程成渣过程及磷的赋存形式。研究表明：在提钒转炉生产过程可以加入石灰对铁水进行脱磷，钒和磷的氧化与成渣过程互不影响，但必须加强炉内搅拌能力才能保证磷的有效脱除。Processing slag and ending slag of vanadium-extraction converter was analyzed and the slag formation and the existing form of phosphorus in the slag had been investigated. It is found out that addition of lime into the vanadium-extraction converter during production can achieve dephosphorization from mol- ten iron, and oxidation of vanadium and phosphorus do not affect each other, but the stirring intensity of the furnace shall be increase to achieve effectively remove phosphorus.
