Abstract

A pressing arrangement (100) is disclosed. The pressing arrangement (100) comprises a pressure vessel (2) comprising a pressure cylinder (1), a top end closure (3) and a bottom end closure (9), a furnace chamber (18) for heating a pressure medium, a plurality of guiding passages (10, 11, 13), a load compartment (19) configured for holding at least one article to be treated, and at least one flow generator (30, 32) for circulating pressure medium within the pressure vessel. The pressing arrangement further comprises a heat exchanging element (170) arranged in the top end closure or in the bottom end closure. The heat exchanging element comprises at least one passage for allowing a flow of pressure medium through the heat exchanging element, and at least one circuit for allowing a circulation of cooling medium within the at least one circuit for a cooling of the pressure medium.

Description

technical field [0001] The present invention relates generally to the field of pressure treatment. In particular, the invention relates to a pressing device for processing at least one article by means of hot pressing, such as hot isostatic pressing (HIP). Background technique [0002] Hot isostatic pressing (HIP) can for example be used to reduce or even eliminate porosity in castings (eg turbine blades) in order to significantly increase their service life and strength (eg their fatigue strength). In addition, HIP can also be used to manufacture products by compressing powders, where the powders are potted in metal sheet pouches to give the product the desired shape. HIP is of particular interest for providing products where complete or substantially complete densification and non-porous or substantially non-porous outer surfaces and the like are desired or required. [0003] Articles to be pressure treated by HIP may be positioned in a load compartment or chamber of an ...
