摘　　要：针对钼铁冶炼提出了一种成本低、周期短,污染低的新的工艺,将含钼酸钙废料作为原料制备球团用以生产钼铁。采用正交试验和单因素试验进行造球并对球团的强度进行检测,分析粘结剂用量、水分含量以及造球时间3个因素对生球性能的影响,并对所生产的钼铁进行成分检测。试验结果表明:将钼酸钙作为原料加入到球团中生产钼铁是可行的。并且当钼酸钙加入量(质量分数)为10%、水分质量分数为8%、膨润土添加量(质量分数)为2%、造球时间为22min时含钼废球团性能最佳,在此球团工艺条件下所生产的钼铁Mo质量分数达61.04%,为60Mo Fe,并符合GB/T 3649—2008中60Mo Fe的要求。A new process with low cost,short cycle,and low pollution was proposed for ferromolybdenum smelting.Calcium molybdate waste was used as raw material to prepare pellets for ferromolybdenum production.Orthogonal experiment and single factor experiment were used to prepare pellets and the strength of pellets was tested.The effects of binder dosage,moisture,and pelletizing time on the properties of green pellets were analyzed,and the composition of molybdenum iron was tested.The results show that it is possible to produce ferromolybdenum by adding calcium molybdate as a raw material to pellets.The performance of molybdenumcontaining waste pellets is best when the addition of calcium molybdate is 10 wt.%,the moisture content is 8 wt.%,the additional amount of bentonite is 2 wt.%,and the pelletizing time is 22min,the performance of molybdenum-containing waste pellets is the best.Under the pelletizing process conditions,the Mo content of the molybdenum iron produced is 61.04 wt.%,which is 60MoFe and meets the requirements of 60MoFe in GB/T3649-2008.A new process technology for ferromolybdenum smelting and calcium molybdate resource utilization was provided.
