摘　　要：研究了褐铁矿配比对钒钛磁铁矿烧结基础性能的影响。研究结果表明，钒钛混合矿的同化温度随着褐铁矿配比的升高而降低，液相流动性指数随着褐铁矿配比的升高而升高，黏结相强度随着褐铁矿配比的升高先升高后降低。不同褐铁矿配比的钒钛混合矿同化温度在1302-1315℃，液相流动性指数在1．12～1．32，黏结相强度为4628～5198N。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混合矿同化性、液相流动性和黏结相强度的影响，得出1号褐铁矿配比为10％（褐铁矿总配比37．2％）时，烧结配矿方案最优。The influence of the ratios of limonite on the basic characteristics of vanadium titanium magnetite was investigated. The results show that the assimilation temperature of vanadium titanium mixed ore decreases with the increasing of the ratio of limonite. The liquid phase fluidity index of vanadium titanium mixed ores rises with the increasing of the ratio of limonite. The binding phase strength of vanadium titanium mixed ores rises at first and then decreases with the increasing of the ratio of limonite. The assimilation temperature of vanadium titanium mixed ores is 1 302-1 315℃, the liquid phase fluidity index is 1.12- 1.32 and the binding phase strength is 4 628-5 198 N in different ratios of limonite. Based on comprehensive utilization of low-priced materials,decrease the cost of production and improve the quality of vanadium-titanium sinter,analyzed the influence of the ratio of limonite on the basic characteristics of vanadium titanium magnetite, the sintering ore-blending scheme is best when the ratio of limonite is 10% and the total ratio of limonite is 37.2%.
