The Experimental Study on Direct Reduction of Shaft Furnace Based Gas of Vanadium Titanium Magnetite

State Key Laboratory of Advanced Steel Process and Products, Central Iron and Steel Research Institute, Beijing 100081, China

摘要: 针对钒钛磁铁矿的特点及利用难点,研究了钒钛磁铁矿气基还原过程及其影响因素,讨论了还原温度、还原时间、还原气氛和气体流量对钒钛磁铁矿还原率和金属化率的影响。试验结果表明,钒钛磁铁矿试样在还原温度为1 000℃,还原时间为2 h,还原气氛为21%CO+55%H₂+24%N₂,还原气体流量为13.26 L/min的条件下,可得到还原率为96.72%,金属化率为92.05%的良好结果。采用气基竖炉直接还原工艺流程,能够将钒钛磁铁矿中的铁氧化物还原为金属铁,实现铁的高效富集。

Abstract: The gas based reduction behavior and the influence factors of vanadium titano magnetite were studied. The influence of reduction temperature,reduction time,reduction atmosphere and gas flow rate on percent of reduction and metallization rate were analyzed. The result shows that the percent of reduction is 96.72%,the metallization rate is 92.05% when temperature is 1 000 ℃,time is 2 h,atmosphere is 21%CO+55%H₂+24%N₂,gas flow rate is 13.26 L/min. The Fe of iron oxide of vanadium titano magnetite can be reduced,and realize efficient enrichment of Fe by using gas based shaft furnace direct reaction.
