摘　　要：以烧结矿、球团矿及其混矿为研究对象,利用荷重软化滴落设备,分别探索了氧气高炉和传统高炉条件下烧结矿、球团矿、混合矿软熔特性。研究发现,与传统高炉气氛相比,在氧气高炉气氛下烧结矿、球团矿、混矿软化开始温度降低,软化结束温度升高,烧结矿滴落温度降低,球团矿与混矿滴落温度升高,并且熔滴区间减小甚至消失。通过对软熔过程相关数据分析,发现在氧气高炉气氛下混矿有一定的交互作用,提高了炉料透气性。The softening-melting characteristics of sinter, pellet and mixed ore in oxygen blast furnace and traditional blast furnace were studied by using load softening and dropping equipment. It is found that, compared with the traditional blast furnace under the softening starting temperature of sinter, pellet, and their mixture decreases, the softening ending temperature increases in oxygen blast furnace atmosphere. Under the condition of oxygen blast furnace, the dropping temperature of sinter decreases, the dropping temperature of pellets and their mixture increases, and dropping zone becomes narrow and even disappears. Through the analysis of the data of the soft melting process, it is found that the mixed ore has a certain interaction effect in the oxygen blast furnace atmosphere, which improves the gas permeability of the charge.
