焙烧温度对烧结矿质量和化学成分都将产生一定的影响，通常而言，对质量的影响更大，尤其对强度、矿相结构的影响较大，对化学成分的影响一般较小，本报告通过化验分析，揭示了焙烧温度对化学成分的影响。结果表明，在1300℃，1325℃条件下，烧结矿的TFe，SiO₂，Al₂O₃基本相同，但MgO，CaO有一定差异，表明温度对矿石与熔剂的反应有一定的影响。另外，FeO的差别较大，1300℃，1325℃烧结矿FeO分别为7.14%，5.32%，主要是由于温度越高，料层内氧化越容易发生，导致其FeO含量越低。

Roasting temperature will have a certain impact on sinter quality and chemical composition. Generally speaking, it has a greater impact on quality, especially on strength and mineral phase structure, and generally has a smaller impact on chemical composition. This report reveals the impact of roasting temperature on chemical composition through laboratory analysis. The results show that the TFE, SiO2 and Al2O3 of sinter are basically the same at 1300 ℃ and 1325 ℃, but there are some differences in MgO and Cao, indicating that the temperature has a certain effect on the reaction between ore and flux. In addition, FeO varies greatly. FeO of sinter at 1300 ℃ and 1325 ℃ are 7.14% and 5.32% respectively, mainly because the higher the temperature, the easier oxidation in the material layer, resulting in the lower FeO content.
