对流化状态下赤铁矿粉附碳后的物相组成、显微结构、化学组成及矿粉被还原程度进行研究。通过矿相分析、电子显微镜分析、X射线衍射分析、穆斯堡尔谱学分析 ,发现流化状态下的赤铁矿粉随附碳时间的延长 ,颗粒结构变得疏松多孔 ,还原程度加深 ,颗粒表面形成的金属铁很少 ,有利于防止粘结。 The phase composition, microstructure, chemical composition and the degree of reduction of slag were studied after the carbonized hematite powder was fluidized. Through the analysis of mineralogical phase, electronmicroscope, X-ray diffraction and Mossbauer spectroscopy, it is found that the hematite powder in the fluidized state is extended with carbon time, the particle structure becomes loose and porous, the degree of reduction is deepened, Fewer metallic iron is formed on the surface of the particles to help prevent sticking.
