A device for hot isostatic pressing comprises a pressure vessel (1), a heat-insulating casing arranged inside the pressure vessel (1), a furnace chamber (3) enclosed by the casing (4), and, arranged therein, a load compartment (5) for receiving articles (6) to be pressed, a control means (11) which is arranged between the load compartment (5) and an inner roof (10) of the casing (4), and defines a space (12) between itself and said inner roof (10), the control means (11) being arranged to control a flow of a pressure medium from the load compartment (5) to said space (12) and thence to an area close to a side wall (19) of the casing (4), and said control means (11) comprising at least one opening (13) to permit said flow of pressure medium from the load compartment (5) to said space (12). The opening (13) emerges into said space (12) at a level higher than the level at which a peripheral part (14) of the control means (11) is located in an area near the wall (19) of the casing (4). |
