A comparative study was made of the reduction kinetics for high temperature smelting of vadium-titanium-containing magnetite,together with Hainan iron ore,using iron bath method.Three peaks were revealed on the reduction rate curves for the magnetite,while one peak only for Hainan ore.Under the same conditions,the smelting reduction rate of the magnetite was found to be lower than that of Hainan ore.The rate increases evidently with the increase of the bath volume.The expressions of smelting reduction rate were suggested for the reduction with and without iron bath respectively.

用铁浴法对钒钛磁铁矿在高温熔态下还原动力学进行了研究。结果表明:钒钛磁铁矿熔融还原速度有三个高峰期,而普通海南矿则只有一个高峰期,在相同条件下,钒钛磁铁矿熔融还原速度低于海南矿的还原速度;铁浴量增加,还原速度明显增高,提出了钒钛磁铁矿在有铁浴和无铁浴条件下熔融还原反应速度方程。
