摘　　要：针对攀钢高钛型钒钛磁铁精矿烧结的特点,在实验室采用造小球焙烧的方法,进行了配碳、焙烧温度、焙烧时间等因素对钒钛烧结矿铁酸钙生成影响的试验研究。结果表明,烧结温度、气氛、碱度是影响钒钛烧结矿铁酸钙生成的最主要因素,而在化学成分中,TiO2、Al2O3对铁酸钙生成量和形态的影响较大。因此,在攀钢高钛型钒钛磁铁精矿烧结条件下,建立有利于生成细针状铁酸钙适宜的烧结工艺制度,消除TiO2、Al2O3的不利影响,是改善攀钢钒钛烧结矿品质的关键。The test on the influence factors of calcium ferrite generation during Vanadium-Titanium iron ore cooeentrates sintering was conducted in laboratory with making mini-pellets manner. The results show that sintering temperature, sintering atmosphere and basieity are main operating factors influencing calcium ferrite generation, whereas the TiO2, Al2O3 are main chemical compositions influencing calcium ferrite generation and its structure. So, for the PANZHIHUA Vanadium-Titanium iron ore concentrates sintering production, it is necessary to establish proper process schedule for needle-like calcium ferrite formation, and prevention the disadvantage influence of TiO2, Al2O3.
