Influence of Iron Ore Characteristics on FeO Formation During Sintering

The influence of iron ore characteristics 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...

More Information
Summary:The influence of iron ore characteristics 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 LOI （loss on ignition） in iron ores 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.
