摘　　要：通过对多种加料方式下以及转炉终点不同工艺参数下MoO3还原效果的比较,在实验室研究了纯铁液对MoO3的还原。结果表明:MoO3能被纯铁液快速还原吸收。在铁液面上先加入粉状MoO3,随后加渣,MoO3在几分钟内即可被还原完毕,钼收得率最高可达96%;所有加料方式下MoO3的终还原率基本都在95%以上。混合加料方式下,在实验研究的范围内,随着温度的升高,渣中FeO含量的降低,(MoO3)的还原速度和终还原率有明显的升高或升高趋势,而碱度对此基本无影响。The experimental study on reduction of MoO3 by pure liquid iron was carried out in the lab by the comparison of reduction effects with various feeding modes and different process parameters of the end-point refining of converter. The results show that MoO3 can be reduced and absorbed quickly by pure liquid iron. MoO3 reduction can be completed in a few minutes and molybdenum yield may come up to 96% when MoO3 powder is first fed on the surface of liquid iron and slags followed. The MoO3 final reduction ratio is above 95% under all feeding modes. Under the mode of admixture adding both the MoO3 reduction rate and final reduction ratio increase or show a tendency to increase with increase of temperature and decrease of FeO whereas slag basicity has no effect on them.
