EFFECT OF ORDINARY MAGNETITE RATIOS ON THE BASIC CHARACTERISTICS OF HONGGE HIGH-CHROMIUM VANADIUM-TITANIUM MIXED ORES

摘要

The micro-sinter method was used to investigate the effect of ordinary magnetite (OM) ratios on the basic characteristics of Hongge high-chromium vanadium-titanium (HCVTM). The assimilation characteristic, crystal intensity characteristic, bonding strength characteristic and fluidity characteristic were studied. With the increase of OM ratios in HCVTM, the lowest assimilation temperature (LAT) of mixed ores decreases 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% OM. Meanwhile, the bonding strength (BS) decreases from 4152 N to 1781 N, and the fluidity index of liquid (FIL) rises from 0.035 to 0.14 with increasing OM ratios.
