Abstract: According to sintering proportioning of Xuangang,the influence of FeO on properties of sinters containing titanium was investigated by mini- sintering test and sinter pot test. The results show that FeO has a great effect on the quality of sinter in the process of sintering. With the content of FeO increasing,the assimilation temperature of sinter decrease,the binding phase strength rise and the liquid phase fluidity rise first and then decrease. The sintering cup test verified that increasing FeOcontent led to high tumbler index,which agreed with the effect of FeO on the basic characteristics of the sinter. The optimal content of FeO in the mixed ore was 14.43%~16.19%. The FeO content in the sinter was reasonablly controlled and the law of FeO on sinter was used,which were important for comprehensive utilization of mineral resources and optimization ore proportioning.
