摘　　要：对宣钢单种含钛铁矿粉的烧结基础特性进行了测定,根据混匀矿烧结基础特性进行了优化配矿试验。结果表明：烧结矿的转鼓指数随着混匀矿黏结相强度的增加而增大,低温还原粉化指数和中温还原性随混匀矿液相流动性的增大而增大。宣钢低钛型混匀矿的适宜烧结基础特性：同化性温度为1 300～1 319℃,液相流动性指数为2.56～3.50,黏结相强度为4 100～4 200 N,烧结技术指标和烧结矿性能最优。Sintering basic characteristics of Xuanhua Steel single titanium containing iron ore powder were determined in order to conduct match optimization test. The results showed that sinter tumbler index increased with increasing mixed iron ore binding phase strength,while low temperature RDI index and moderate temperature reduction of mixed iron ore increased as liquid phase fluidity index increased. The suitable sintering basic characteristics of Xuanhua Steel low titanium type of mixed iron ore are as follows：the assimilation temperature is 1 300 ～ 1 319 ℃,the liquid phase fluidity index is 2. 56 ～ 3. 50,the binding phase strength is 4 100 ～ 4 200 N,under these conditions the optimal technical index of sintering and sinter performance can be achieved.
