In this paper, the fluidization characteristics of the magnesia fluidized bed and the heat transfer characteristics with the specimen (SM55C) plunged in the bed have been investigated. To characterize the fluidization, the minimum fluidizing velocities and the relation ships between bed voidage and fluidization rate and obtained. To characterize heat transfer, the experiments for finding heating time transfer effect have been carried out by varying the magnesia particles sizes. optimum heating condition in the magnesia fluidized bed is obtained.
