ABSTRACT:
Disclosed is a continuous atmosphere controlled furnace for aluminum brazing and other purposes. A plurality of pots are suspended from a circular roof rotatable in a horizontal plane and arranged in a circle having a center on the axis of rotation of the roof. Each pot comprises a body having an open top and a cover capable of closing the open top of the body. The open top of each pot projects above the roof and that portion of each pot which contains the material to be heated extends downwardly below the roof. The material to be heated is supported on a hanger depending from the cover of each pot and the cover is lowered to place the material in the pot and close the pot. The furnace further includes an atmosphere gas distributor having its center on the axis of rotation of the roof and connected to the pots by gas supply and exhaust ducts. A method of supplying atmosphere gas through the pots is also described.
