The measurement method and quantitative indexes of iron ore consolidation characteristic temperature (CCT) during roasting, including consolidation starting temperature, highest consolidation rate temperature, and consolidation termination temperature, were improved based on previous research. The mineral properties of V–Ti magnetite (Panzhihua) were analyzed, and the CCT of V–Ti magnetite was calculated. To investigate the effect of mineral types on CCT, a series of trials were carried out by using various ores, including high-grade magnetite ore, high silicon iron ore, and V–Ti magnetite ore. The greatest shrinkage of V–Ti magnetite was 6.7%, the consolidation starting temperature was 991 °C, and the termination temperature was 1384 °C. The results of X-ray diffraction analysis indicated that the V–Ti magnetite ore was composed of titanomagnetite, peridotite, and other minerals, which is more complicated than conventional magnetite. As a result, the temperature at the maximum rate of consolidation and the temperature at the termination of consolidation are the greatest. FeTiO₃ and MgFe₂O₄ in V–Ti magnetite may inhibit the creation of sinter necks between hematite particles. Liquid phase occurs inside the pellet when the temperature surpasses 1250 °C, which may accelerate particle growth and the formation of a sintering neck within the pellets.

在前人研究的基础上，改进了铁矿石焙烧固结特征温度（CCT）的测量方法和定量指标，包括固结起始温度、最高固结速率温度和固结终止温度。分析了V-Ti磁铁矿（攀枝花）的矿物性质，计算了V-Ti磁铁矿的CCT。为了研究矿物类型对 CCT 的影响，使用各种矿石进行了一系列试验，包括高品位磁铁矿、高硅铁矿和 V-Ti 磁铁矿。V-Ti磁铁矿的最大收缩率为6.7%，固结起始温度为991 ℃，终止温度为1384 ℃。X射线衍射分析结果表明，钒钛磁铁矿由钛磁铁矿、橄榄岩等矿物组成，比常规磁铁矿复杂。结果，最大固结速率处的温度和固结终止处的温度最大。钛酸铁_{V-Ti 磁铁矿中的3}和 MgFe ₂ O ₄可能会抑制赤铁矿颗粒之间烧结颈的产生。当温度超过 1250°C 时，颗粒内部会出现液相，这可能会加速颗粒生长和颗粒内烧结颈的形成。
