摘要：

The influence of iron ore characteristic On FeO formation during sintering was examined mainly in terms of chemical composition and the melting characteristics of iron ores. Statistical regression and X-ray diffraction were used to further explain the specific effect of iron ore characteristics on FeO formation. The results indicate that LOT (loss on ignition) in iron Ore have a positive influence on FeO formation by promoting the sintering process of Fe2O3 decomposing and reducing. Silica contents in iron ores play a determining role in final content of FeO in sinter. The melting characteristics of iron ores significantly affect FeO formation during sintering.
