Abstract

The main aim of this work was to optimize the proportions of vanadium and titanium iron ore from diverse sources in sinter mixture. Industrial V - Ti sinter was observed firstly, then 16 groups of sinter using different proportions V – Ti ore from diverse sources, designed through orthogonal method, were prepared by sinter pot, and their performances were determined. It showed that, V - Ti sinter had complex mineral compositions, particularly perovskite (CaO•TiO2). V - Ti ores from diverse sources had different impacts on V - Ti sinter properties. V - Ti sinter should be sprayed with proper CaCl2 to improving the lower reduction degradation index (RDI+3, 15). And the V - Ti sinter mixture with 5 % DaBa n (DB), 25 % HengWei (HW), 25 % YuanTong (YT), 45 % JianLong (JL) ore was optimal.
