PROBLEM TO BE SOLVED: To provide a fluidized bed reaction furnace for producing iron carbide capable of enhancing a reduction reaction rate. SOLUTION: This fluidized bed reaction furnace for producing iron carbide 3 has a gas-blowing part at the lower part, and a fluidized bed-forming part for forming a successive fluidized bed by separating the fluidized bed by a baffle plate 13 formed on the upper part thereof. The gas-blowing part is separated according to a reduction reaction zone of an ironstone and a carbonization reaction zone of iron of the upper fluidized bed, and charging means for charging the most suitable gases for the each reaction to each division are installed. |
