摘　　要：采用微型烧结装置,对8种不同氟含量的白云鄂博混合铁精矿进行了烧结基础特性的实验研究.结果表明,随氟含量的增加,铁矿粉的液相流动性指数增大,粘结相自身强度下降,烧结矿宏观上呈现薄壁多孔结构,微观上形成以枪晶石为主要粘结相,多种矿物共存结构.The basic sintering characteristics of eight kinds of Balyunebo iron ores with different fluorine content wete investigated by a mini-sintering test device. The result indicates that the index of liquid phase fluidity of iron ores increases and the serf-intensity of bonding phase decreases with increasing the fluorine content. Thin-walled pores appear on the macrostructure of the sinter, while cuspidine becomes the main bonding phase with many minerals coexisting on the microstructure.

关 键 词：氟 液相流动性 粘结相自身强度
