摘　　要：为了探索碳热还原钒钛磁铁矿的机理,运用FACTSage软件对钒钛磁铁矿碳热还原过程进行了理论计算。结果表明,金属Fe和Ti的起始还原温度分别为700℃和1300℃左右,随着温度的升高,液相中金属的生成量逐渐增加。配碳量对金属液相的产生影响较大,配碳为16%时,出现金属液相的温度为1550℃;配碳量大于18%时,金属液相产生的温度降低到1180℃。碱度对Fe回收率影响不大;而当碱度为0.4时,Ti的回收率最高。当配碳量为20%、碱度为0.4时,Fe、Ti的还原效果最好。In order to study the mechanism of the carbon reduction of vanadium bearing titan-magnetite in microwave,we conduct theoretic calculation for carbon reduction of vanadium bearing titan-magnetite in microwave by using FACTSage.The result of theoretic calculation shows that the metal Fe and Ti appeared when temperature was around 700 ℃ and1 300 ℃,respectively.And with the increase of temperature,the amount of metals in the liquid raised.The carbon dosage has a great impact on the production of the liquid metal.The temperature of liquid metal phase starts to appear is 1 550 ℃ when carbon dosage is 16% and 1 180 ℃ when the carbon dosage is more than 18%.The basicity has little influence on reduction of Fe,but the recovery ratio of Ti seems to be the highest when the basicity is 0.4.Moreover,the recovery ratio of Fe and Ti is the highest when the carbon dosage is 20% and basicity is 0.4.
