Abstract: 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.
