摘要：This invention provides a fluidized-bed furnace, in which the work piece is heat-treated in a fluidized bed formed by filling a vessel with particles and blowing hot air into the vessel to fluidize the particles. It includes a cantilevered dispersion tube disposed in the fluidized bed, and provided with air outlets directed downward, from which the hot air is blown out. This invention also provides a heat-treatment apparatus incorporating a rotary heat-treatment furnace, in which a work piece is heat-treated while being rotated in the fluidized bed, as the solution and/or aging treatment furnaces; removing dust from the exhaust gases discharged from the solution treatment furnace by a dust collector, and recovering the waste heat from the exhaust gases by an heat exchanger as the heat source for the aging treatment furnace; and also incorporating an automatic carrier which charges or discharges the work piece into or out of each furnace. The fluidized-bed furnace is improved to require a lower investment cost and smaller space and prevent thermal energy loss more efficiently than the conventional one, and suitable for a heat treatment furnace for metals, e.g., Al alloy.
