Abstract
In an aspect of at least one embodiment of the invention, there is provided a hot isostatic pressing arrangement for treatment of articles by hot isostatic pressing. The arrangement includes a pressure vessel including a furnace chamber including a heat insulated casing and a furnace for heating of a pressure medium during pressing, and a 'heat exchanger unit' or heat absorbing material located below the furnace chamber. In another aspect of at least one embodiment of the invention, there is provided a method for treatment of articles in a hot isostatic press. The press further includes a pressure vessel enclosing a furnace chamber and a 'heat exchanger unit'. The method includes the steps of loading the articles into the furnace chamber, performing pressurized and heated treatment of the articles, cooling the articles and unloading of the articles. All the steps are performed while the ‘heat exchanger unit’ remains located inside the pressure vessel. Heat is transferred to and from the ‘heat exchanger unit’ at different portions of the hot isostatic pressing cycle.
