Abstract:
It is vitally important that guide sintering ore blending work by deeply acquiring the room and high-temperature characteristics of iron ore. For high-temperature characteristics, particularly, they could reflect the high-temperature behaviors and effects in the process of sintering. In this paper, the 5 kinds of basic sintering characteristics (assimilation, fluidity of liquid phase, SFCA generative capacity, strength of melting phase and strength of joined crystal) and two new proposed high-temperature characteristics (fusion and liquid absorbability) were introduced, respectively. And then, through the experimental investigation, the optimizing ore blending technology base on the principle of complementary ore blending of assimilation and fluidity of liquid phase characteristics and large particles divided adding technology based on the control of liquid absorbability of larger limonite particles were presented. The result of sinter pot test indicates that good sintering indexes were obtained, which proves the superiority of ore blending based on high-temperature characteristics of iron ores. Finally, the future prospects of optimization technology of iron ore blending for sintering were discussed from two sides, one is the sintering optimization expert system based on the high-temperature characteristics of fine iron ores, another is the sintering process optimization based on the deterioration of fine iron ores.
