Abstract: To investigate the effect of Al2O3 on the reduction and high temperature properties of sintered ores, the heating-up reduction of sintered ores varying the Al2O3 content are carried out. The early softening, the increase of pressure drop, and meltdown temperature were observed at lower temperature with increase of Al2O3 content. From the simultaneous X ray observation of reduction process and EPMA and SEM analysis of quenched samples, a relatively large amount of Wüstite-Gehlenite eutectic phase was observed in the early stage of reduction process at high Al2O3 content sintered ores. Based on these results, it is concluded that Al2O3 rich molten phase was produced at the relatively low temperature with the increase of Al2O3 content.
