<p>A fluidized bed heat treating furnace (1) used for the solution heat treatment of metal products made of aluminum alloy and for heat treatment such as quenching and tempering which is capable of mainly supplying heat energy through a heat transfer tube (6), characterized in that spoilers (11) and (12) are installed on the heat transfer tube (6) so as to prevent a part of a fluidized medium (8) from being non-fluidized using an air flow flowing around the heat transfer tube (6), to prevent the top part of the heat transfer tube (6) from being overheated or molten down, and to enable the heat transfer tube (6) to be increased in size in order to increase a thermal efficiency and facilitate the temperature control of the fluidized medium (8) contained in a fluidizing chamber (2).</p> |
