摘　　要：烧结矿靠流动的液相粘结未熔物获得强度,液相流动能力是铁矿粉的一个烧结基础特性.本文提出评价铁矿粉烧结过程中液相流动性的两个新指标,即"基于温度分布的液相流动面积"以及"液相流动对温度的敏感性",并给出这两个指标相应的计算式以便正确把握烧结过程液相行为及优化烧结配矿.The sinter is consolidated by fluid liquid phase through adhering the adjacent not-molten materials, and the fluidity of liquid phase is a sintering basic characteristics of iron ore. Two new evaluation indexes, the liquid phase fluidity area based on temperature distribution （FAT） and the index of sensitivity of fluidity to temperature （ISFT）, were proposed. Their corresponding calculation formulas were given to rightly master the action of liquid phase in sintering and optimize ore-matching.
