同样配矿条件，碱度、化学成分要求基本一致的3条产线，因烧结装备及操作参数略有差异，导致烧结矿强度、高炉使用情况存在一定的不同，因此，对烧结矿SiO2,Al2O3,CaO,MgO,P2O5,FeO,T.Fe,T.C,S,LOI进行了分析对比，结果表明，2,3,4DL的FeO控制水平，TFe含量存在一定的差异，为高炉提供了参考数据。

For the three production lines with the same ore blending conditions, basicity and chemical composition requirements, there are certain differences in sinter strength and blast furnace use due to slight differences in sintering equipment and operating parameters. Therefore, the analysis and comparison of sinter SiO2, Al2O3, Cao, MgO, P2O5, FeO, T.Fe, T.C, s and LOI show that there are certain differences in FeO control level and TFE content of 2,3,4DL, It provides reference data for blast furnace.
