An annealing basket made of steel, receiving mass-produced aluminium parts ( ) for the degreasing and softening thereof, comprising a bottom and side by a frame. At least one side wall ( ) is joined to the walls that protrude from said bottom and are defined frame ( ) by means of at least one aluminium element ( ) that can be plastically deformed when heated to an annealing temperature as a result of the pressure that is exerted on the side walls ( ) and occurs in the annealing basket ( ) due to thermal expansion of said aluminium parts ( ), whereby the side wall ( ) moves outwards to a certain degree under the effect of the increase in the volume of said basket in at least one area that is adjacent to the frame.

Annealing basket for degreasing and softening aluminum parts

Device and process for operation of open baking furnaces, in particular such ring-type furnaces for manufacturing anodes for the aluminum electrolytic process, are such that for each so called fire the sealing chamber and/or chamber in the cooling zone can be saved in that the flue gas exhaust manifold is not situated on the headwall but instead on the flue and/or the opening of that headwall on which the last fresh air supply manifold is situated is closed off by a sliding baffle. Openings corresponding in cross section to that of the connected part of the flue gas exhaust manifold are provided in the region of the flues. The advantage of the process lies in the greater flexibility in furnace operation, which results either in an increase in production or an increase in product quality.
