以CaO和CaF_2作为熔剂对含钒铁水进行浸入吹氧脱硅处理时,铁水中钒的氧化损失程度主要取决于渣铁间化学反应偏离平衡状态的程度。为了减少钒的氧化损失,炉渣应有良好的流动性,使氧化铁含量保持在较低的水平。在合适的温度、供氧强度、熔剂加入量等工艺条件下,当硅由0.65％脱除至0.15％左右时,可将铁水中钒的氧化损失率控制在10％左右。 When CaO and CaF_2 are used as fluxes, the vanadium oxidation loss in hot metal mainly depends on the degree of chemical reaction between slag and iron deviating from the equilibrium state. In order to reduce the loss of vanadium oxidation, the slag should have good fluidity, keeping the iron oxide content at a low level. When the silicon is removed from 0.65% to about 0.15%, the oxidation loss rate of vanadium in molten iron can be controlled at about 10% at the proper temperature, oxygen supply intensity and flux addition.
