摘　　要：系统地研究水钢烧结矿及天然矿的冶金性能。研究结果表明,水钢烧结矿具有中等及中等偏下的低温还原粉化性能和优良的还原性能;软化区间偏宽,开始熔化温度高和开始滴落温度高,却有较窄的熔滴区间。在3种进口块矿中,越南块矿的综合冶金性能最好,其次是澳大利亚块矿,印度块矿的综合冶金性能相对要差些。在两种国产块矿中,兰坪块矿的综合冶金性能比清镇块矿好;国产天然矿的综合冶金性能比进口天然矿差。The metallurgical properties of several sinters and natural ores for Shuicheng Iron and Steel Co. , Ltd. were investigated. The results show that the sinters for the BF in Shuicheng Iron and Steel Co. , Ltd. have middle RDI （low temperature reduction degradation index）, choice RI （reduction index）, wider softening temperature range, high start melt and dropping temperature, smaller melt and dropping temperature range. In three imported natural ores, the Vietnamese ore is the best in comprehensive metallurgical properties, followed by the Australian ore and the Indian ore. In the two domestic ores, the Lanping ore is better than the Qingzhen ore in comprehensive metallurgical properties while the domestic ores are generally inferior to the imported ores in comprehensive metallurgical properties.
