Document Type and Number:
Japanese Patent JPS5336810
Kind Code:
B2
Abstract:
A vacuum furnace construction of a type particularly suitable for brazing, heat treating, sintering, annealing and other thermal processing of metal components involving a heating thereof to temperatures ranging up to about 2,300 DEG F. The furnace incorporates a cooling system to effect a rapid cooling of the workpieces at the conclusion of the thermal process without exposing the components to oxidation attack at the high temperatures prevalent in the vacuum furnace during the cooling cycle. The invention further contemplates an improved heat exchanger construction through which an inert cooling gas is adapted to be circulated for reuse in the cooling system of the vacuum furnace.
