摘　　要：本文借助于热重分析法，测定钛磁铁矿碳热还原动力学。试验结果表明，添加碱金属碳酸盐能够加速钛磁铁矿碳热还原反应。Catalytic kinetics of the carbothermic reduction of titanomagnetite concentrate was examined in the temperature range from 900 to 1150℃ . An addition of alkali carbonate enhances the rate of the reduction of titanomagnetite, the catalytic effects are in the order: Na_2CO_3 > Li_2CO_3.
