摘　　要：通过钒钛磁铁精矿的直接还原实验,研究不同配碳量、温度和粒度条件对还原结果的影响,并用磁选分离法测定其还原后的金属化率。实验结果表明,钒钛磁铁矿直接还原实验室最优条件为配碳量13%,还原温度1 350℃,而矿粉粒度则是越小越好。该条件下所得实验样品的金属化率为96.72%。By direct reduction of vanadium titanium magnetite concentrate experiments,this thesis studied the impact of different carbon content,temperature and particle size on the reduction result,and magnetic separation method was applied to determine the reduction rate of metallization. The experimental results show the optimal conditions for vanadium titanium magnetite concentrate direct reduction reaction are： the carbon content 13%,the temperature 1 350 ℃ and mineral powder particle size as small as possible. The metallization rate of the sample under this condition is 96. 72%.
