A solid solution treatment furnace for an aluminum plate is provided to perform solid solution treatment of the product into a plate form with superior mechanical properties by suppressing bending of the product to the utmost and preventing temperature of cooling water in a cooling tank from being locally increased even in the solid solution treatment of a plate-like product which is thinner relative to its volume. A solid solution treatment furnace for an aluminum plate comprises: a heating furnace(1a) installed in an upper part to heat an aluminum plate(9); a transfer car(3) which is installed below the heating furnace, and on which a loading box(4) is loaded to load aluminum plates in the loading box; a cooling tank(2) which is connected to the transfer car through connecting members and moved along rails(1f) by a transfer unit(1e); a lift unit(1c) for lifting the loading box into the heating furnace and lowering the loading box into the cooling tank; and a sliding door(1d) installed at an entrance and an exit of the heating furnace, wherein a blowing pipe(2b) in which a plurality of through holes are formed is arranged on the bottom of the cooling tank, and a vortex flow is generated in the cooling water by forcibly injecting air into the cooling tank through a blower(2a) and generating a large amount of air bubbles in cooling water contained in the cooling tank. |
