At present, the burden of blast furnace is mainly sinter. However, the pulverization of the sinter at low temperature reduction in upper portion of the blast furnace is severe, therefore, it is necessary to study the mechanism of its pulverization. Review the effects of alkalinity, MgO and Al₂O₃ on the pulverization performance of sinter at low temperature. The effect of the same composition on low temperature reduction degradation properties is different. Through this paper, a more comprehensive understanding of the mechanism of sintering pulverization performance at low temperature is acquired. Meanwhile, providing reference for sinter at low temperature.
