Reduction Behavior of Bituminous Coal Coated Magnetite Powder

In order to restrain the agglomeration and loss of flow of iron ore powder in fluidized reduction process,the method of bituminous coal coated magnetite powder was adopted.The reduction behavior of bituminous coal coated magnetite powder was studied the morphology based on ore powder during reduction.The reduction samples of bituminous coal coated magnetite powder at different temperatures were characterized by SEM,EDS and XRD,and the results were compared and analyzed.It is concluded that the reaction process between solid carbon and iron ore powder can be effectively improved by increasing temperature,and the formation of iron whiskers can be effectively inhibited by coating magnetite powder with bituminous coal carbon.
