There are many factors influencing the sinter reduction and low temperature reduction degradation index, the quantitative conclusions for single influence factors have been obtained by many researchers, but few researches on comprehensive influence after intersection of multiple factors have been carried out. Through adjustment of ore proportioning and process parameters, the sinter with great difference in basicity, MgO content and FeO content is obtained, and its reducibility and low temperature reduction degradation index (RDI) are tested. On this basis, the obtained data are processed by MINITAB analysis software, and the regression equation influencing the sinter reducibility and RDI is also obtained. The regression equation proposed is of great guiding significance for Bayi Steel sinter production. According the needs of iron making, by adjusting ore proportioning structure and process parameters in sinter plants, the sinter with reasonable reducibility can be obtained for use in BF and COREX furnace.
