Abstract
An isostatic press for hot isostatic pressing having a pressure vessel (1) in which a furnace chamber (2) is arranged with a space (3) between the furnace chamber (2) and the walls of the pressure vessel (2). The furnace chamber (2) has a heat-insulating mantle and heat-insulating top wall and bottom wall, and passageways (5, 6) are arranged in the walls of the furnace chamber (2). A gas outlet means is arranged in the interior of the furnace chamber (2). Gas is removed directly from the furnace chamber (2) by the gas outlet means. Advantages include that treated articles (11) are cooled rapidly, as cooling takes place during the same time as decompression. Articles (11) may also be rapidly cooled to a temperature at which they are easily handled.
