利用差热分析的方法可以研究物质相变及相变温度。铁矿石在其软熔过程中伴随一系列相变过程,特别是在软化开始阶段和熔化阶段有液相生成和大量发展,在差热曲线上将出现明显的吸热谷。因此,根据差热曲线可以获得有关铁矿石软熔性能的资料。本文系讨论LKAB酸性球团矿(MPB)、橄榄石球团矿(MPBO)和高碱度球团矿(MPBB)的
Differential thermal analysis method can be used to study the material phase transition and phase transition temperature. Iron ore is accompanied by a series of phase transitions during its reflow process. In particular, liquid phase formation and mass development occur at the initial stage of softening and the melting stage, and a pronounced endothermic valley will appear on the differential thermal curve. Therefore, according to the differential thermal curve can be obtained about the reflow properties of iron ore information. This article discusses the LKAB acidic pellets (MPB), olivine pellets (MPBO) and high basicity pellets (MPBB)
