摘　　要：烧结矿作为高炉主要原料之一,其冶金性能对高炉生产技术经济指标有着重要影响。FeO是烧结矿的一种主要成分,也是一项评价烧结矿冶金性能的主要指标。以某钢铁公司现场所生产的烧结矿为主要原料,研究了FeO对烧结矿还原性RI、低温还原粉化率RDI+3.15和软熔性能的影响,从理论上说明了FeO含量对烧结矿冶金性能的影响。Sinter is one of the main raw materials of blast furnace,and its metallurgical properties have the important influence on the technical and economic indicators of blast furnace production.FeO is a main component of sinter,and it is also a main indicator for evaluating the metallurgical properties of sinter.Taking the sinter produced by certain iron&steel company as the main raw material,study the influence of FeO on the reductive RI,low-temperature reduction and pluverization rate RDI+3.15 and reflow performance of the sinter,and theoretically explain the influence of FeO content on the metallurgical properties of thesinter.
