Claims

[Scope of Claim for Utility Model Registration] (1) In a furnace in which solid particles are housed, heated, and heat-treated by passing a wire through them while being fluidized by gas, The main flow gas chamber and the flow/heating gas chamber are divided and filled with particles on the upper partition wall, while the base end connects to the main flow gas chamber and the ejection hole in the upper end area is located below the wire pass line. Main flow gas distribution nozzles reaching the middle layer level of the granules are vertically installed at intervals, and between the main flow gas distribution nozzles, the base ends are connected to the flow and heating gas chamber, and the upper ends of the ejection portions are connected to the upper partition wall. a first flow/heating gas distribution nozzle projecting upward; and a first flow/heating gas distribution nozzle that surrounds the first flow/heating gas distribution nozzle, the base end of which is closed by a partition wall, and the ejection portion of the upper end serving as the main flow gas distribution nozzle. A fluidized bed heat treatment furnace for wire rods, characterized in that a second gas distribution nozzle for fluidization and heating that stops at a lower level is provided. (2) The scope of the utility model registration claim described in paragraph 1, in which the main flow gas chamber is located in the upper part, the flow and heating gas chamber is located in the lower part, and the first flow and heating gas distribution nozzle penetrates the upper partition wall. Fluidized bed heat treatment furnace for wire rods. (3) The flow of wire rods according to claim 1 of the utility model registration claim, in which the main flow gas chamber is located at the lower level, the flow/heating gas chamber is located at the upper level, and the main flow gas distribution nozzle penetrates the upper partition wall. Layer heat treatment furnace. (4) The fluidized bed heat treatment furnace for wire rods according to any one of claims 1 to 3 of the utility model registration claim, wherein the jetting part of the nozzle has a jetting hole on the side.
