摘要: 研究了褐铁矿配比对钒钛磁铁烧结矿性能的影响。研究结果表明:钒钛磁铁烧结矿的转鼓指数(T)和低温还原粉化指数(RDI+3.15)随着褐铁矿配比的升高先升高后降低,还原度(RI)和荷重开始软化温度(T10%)随着褐铁矿配比的升高而降低。软化区间(ΔT)随着褐铁矿配比的升高先减小后增大。从综合利用低价铁矿石资源,降低生产成本和改善钒钛烧结矿质量的角度,分析褐铁矿配比对钒钛磁铁烧结矿性能的影响,得出1#褐铁矿配比为10%(褐铁矿总配比37.2%)时,烧结配矿方案最优。Abstract: The influence of the ratios of limonite on properties of vanadium-titanium sinter was investigated in this paper.The results show that the tumbler index and RDI+3.15 of vanadium-titanium sinter increases first and then decreases with the increase of the ratio of limonite.The RI and T10% of vanadium-titanium sinter decreases with the increase of the ratio of limonite.The ΔT of vanadium-titanium sinter decreases first and then increases with ratio of limonite increasing.With regards to comprehensive utilization of low-priced materials,reducing production cost and improving the quality of vanadium-titanium sinter,the influence of the ratio of limonite on the properties of vanadium-titanium sinter has been analyzed,which generates the best sintering ore-blending schemewhere the ratio of limonite is 10% and the total ratio of limonite is 37.2%.
