Abstract In order to improve low temperature reduction degradation characteristics of iron ores and adapt to various ironmaking conditions, sinter, pellet, and lump ore which are commonly used in ironmaking production were studied on their low temperature reduction degradation characteristics under different conditions of gas in blast furnace and COREX by controlling the gas composition and temperature. The results show that under the same reduction atmosphere and temperature condition, the reduction degradation characteristics and degrees of different ores are quite different, the sensitivities of which to reducing gas composition and temperature differs from one to another. This study has a certain practicability and reference value for investigating and evaluating low temperature reduction degradation characteristics of different iron ores which is beneficial to improving metallurgical properties of iron ores and optimizing the parameters in different ironmaking processes.
