Taking advantage of the characteristics of fast microwave heating of metallurgical powder material, and combining the good qualities of heat and mass transfer in gas-solid phase spouted fluidized bed, a novel type of metallurgy reactor, spouted fluidized bed with microwave heating, was designed. Characteristics and the operational parameters of the microwave heating fluidized bed were analyzed. Analysis results show the microwave heating spouted fluidized bed is more effective in strengthening solid phase decarburization than the conventional spouted fluidized bed. It can improve the dynamics conditions of traditional fluidized solid phase decarburization. The spouted fluidized bed with microwave heating is a kind with new technology with application value.
