摘　　要：采用回转窑-电炉熔分工艺,研究了钒钛磁铁矿直接还原和熔分工艺,在直接还原过程中考察还原温度、还原时间、配碳量对金属化率的影响,在电炉熔分实验中考察还原温度、还原时间、白云石的添加量对含钒的生铁和含钛的炉渣的影响,从而使得铁、钒、钛最大程度的综合利用。Vanadium-titanium magnetite direct reduction and electric furnace smelting was studied by using Rotary Kiln-electric furnace melting process.The effects of reduction temperature,reduction time and carbon amount on the metallization rate were investigated in the direct reduction process,the effect of reducing temperature,reducing time and adding amount of dolomite on the pig iron containing vanadium and the slag containing titanium was investigated.,thus making the most comprehensive utilization of iron,vanadium,and titanium.

关 键 词：炉渣 还原温度 还原时间 配碳量
