Title:
HOT ISOSTATIC PRESSING DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/186229
Kind Code:
A1
Abstract:
Provided is a hot isostatic pressing (HIP) device that improves the heat uniformity of a hot zone during a pressurization process of an object being processed. This HIP device (100) is provided with: an outer casing (4) having an open outer opening part (4H); an inner casing (5) having an open inner opening part (5H); a heat-insulating body (R) disposed between the outer casing (4) and the inner casing (5); a gas flow generation part (30); and a plurality of first gas conduits (12). A hot zone (P) in which a pressurization process is performed is formed inside the inner casing (5). During the pressurization process, a low-temperature pressurization medium gas which has been generated by the gas flow generation part (30) and has passed through the first gas conduits (12) moves upward in an inner flow passage (L1) between the casings, and then flows into the hot zone (P) from the inner opening part (5H). Even when the pressurization medium gas leaks from the vicinity of a bottom wall part (20) and flows into the hot zone (P), the heat uniformity of the hot zone (P) is maintained.
