Abstract
A hot-isostatic press adapted for rapid cooling of the hot zone after completed pressing and sintering of the material includes a pressure vessel, end closures, and a hot zone surrounded by thermal barriers. Between the thermal barriers and the pressure vessel with end closures there are colder spaces. At least one connection, located in the lower part of the thermal barrier and provided with a valve between the space next to the pressure vessel and the space below the bottom thermal barrier, is provided with an externally controllable valve. In the upper part of the thermal barrier there is an opening with a relatively large cross section and a valve is provided for the opening, which comprises a heat-insulated portion.
