就提高钒钛铁精矿配比对攀钢钒钛烧结矿冶金性能的影响进行了研究。结果表明:钒钛铁精矿配比从46%提高到52%,钒钛烧结矿的FeO含量升高,低温还原粉化率降低,中温还原度降低,软化开始、压差陡升和滴落温度均升高,最大压差升高。本结果可为钒钛铁精矿烧结合理配矿提供指导。
The effect of increasing the ratio of vanadium-titanium-iron concentrates on the metallurgical properties of vanadium-titanium sinter in Panzhihua Iron and Steel Works was studied. The results show that the content of vanadium-titanium-iron ore concentrate increases from 46% to 52%, the content of FeO in the vanadium-titanium sinter increases, the reduction rate of low-temperature reduction decreases, the reduction degree of intermediate temperature decreases, the softening begins, Temperature increases, the maximum pressure rise. The results can provide guidance for the rational distribution of vanadium-titanium-iron ore concentrate.
