HOT ISOSTATIC PRESSING DEVICE

Provided is a hot isostatic pressing (HIP) device (1) that can efficiently cool a hot zone during HIP processing while restraining temperatures in the lower part of a high-pressure container. This HIP device (1) is provided with the following: gas-impermeable casings (3, 4) that surround an object t...

Zusammenfassung:	Provided is a hot isostatic pressing (HIP) device (1) that can efficiently cool a hot zone during HIP processing while restraining temperatures in the lower part of a high-pressure container. This HIP device (1) is provided with the following: gas-impermeable casings (3, 4) that surround an object to be processed (W); a heating unit (7) that is disposed inside these casings and forms a hot zone around the object to be processed (W); a high-pressure container (2); and a cooling unit that guides a pressure-medium gas cooled on the outside of the casings into the hot zone to cool the hot zone. The cooling unit comprises the following: a gas introduction unit that introduces the pressure-medium gas that has been cooled on the outside of the casings (3, 4) into the hot zone; and a cooling promotion unit (37) that cools the pressure medium gas by causing the pressure-medium gas that has been cooled on the outside of the casings to exchange heat with a base (11) of the high-pressure container (2).
