| 摘 要： | 对邯钢5种常用矿粉及其混合矿的烧结基础特性进行了研究。结果表明：巴粗矿粉对混合矿的同化温度和液相流动性的影响最大，澳矿粉对混合矿的粘结相强度影响最大。以粘结相强度为基准，综合考虑同化温度和液相流动性，邯钢最优配矿方案为：澳矿粉(30%~35%)+邯邢精粉(15%~20%)+巴粗矿粉(20%~25%)+杨迪粉(10%~15%)+北非粉(5%~10%)；混合矿中单种矿的烧结基础特性之间存在一定的互补关系，但混合矿烧结基础特性不能简单地由单种矿烧结基础特性的线性加和来确定。

| Abstract: | The sintering basic characteristics of five kinds of iron ore and blending iron ore in Handan Iron and Steel Co. Ltd. were determined. The results show that the effect of Brazil coarse ore on the assimilation temperature and liquid phase fluidity of blending iron ores is the greatest, effect of Australia iron ore on the binding phase strength is the most. Based on the binding phase strength, considered the assimilation temperature and the liquid phase fluidity comprehensively, the optimized ore-blending is that, 30%-35% Australian iron ore + 15%-20% Hanxing concentrate + 20%-25% Brazilian coarse ore + 10%-15% Yandi ore + 5%-10% North Africa ore. The sintering basic characteristics of single iron ore has mutually complementary relationship, but the sintering basic characteristics of blending iron ore can’t determined by a single linear calculation. |
