8th International Congress on Science and Technology of Ironmaking - ICSTI 2018

The effect of ordinary magnetite ratios on the basic characteristics of Hongge high-chromium vanadium-titanium mixed ores was investigated through micro-sinter methods. The researches including assimilation characteristic, crystal intensity characteristic, bonding strength characteristic and fluidity characteristic were studied. With increase of ordinary magnetite ratios in Hongge high-chromium vanadium-titanium mixed ores, the lowest assimilation temperature (LAT) of mixed ores decreases slightly from 1395C to 1324C, the crystal intensity (CI) first decreases and then rises, and the minimum of CI is 4752 N with 30% ordinary magnetite. Meanwhile, the bonding strength (BS) decreases from 4152N to 1781N, and the fluidity index of liquid (FIL) rises from 0.035 to 0.14 with increase of ordinary magnetite ratio. The correlation of FIL with LAT and BC were negative.
