摘要
研究了利用碳还原钒钛铁精矿复合球团通过磨选筛分、氢还原等工序制备还原铁粉的新工艺,并考察了原料粒度、还原温度、还原时间、添加剂Na2SO4及Fe粉用量等因素对铁粉质量的影响。在最佳条件下,还原产品铁粉TFe含量可达到98.01%。
A novel technology for preparation of iron powder from the V-Ti-Fe-concentrate has been investigated in this paper, This technology includes reducing compound agglomeration of V-Ti-Fe-concentrate with carbon powder under the action of microwave radiation , sifting milled compound agglomeration of V - Ti - Fe - concentrate , reducing iron powder by use of hydrogen. Sdditionally, the influences of feed size, reduction temperature, reduction time, additive of Na2SO4 and Fe powder on the iron powder quality were also discussed. And the TFe content in the iron powder reached 98.01% under the optimal conditions.
