Title (EN) HOT ISOSTATIC PRESSING DEVICE
(FR) DISPOSITIF DE COMPRESSION ISOSTATIQUE À CHAUD
(JA) 熱間等方圧加圧装置
Abstract:
(EN) 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.
(FR) Dispositif de compression isostatique à chaud (HIP) qui améliore l'uniformité thermique d'une zone chaude pendant un processus de mise sous pression d'un objet en cours de traitement. Ce dispositif HIP (100) est pourvu : d'un boîtier extérieur (4) comportant une partie d'ouverture extérieure ouverte (4H) ; d'un boîtier intérieur (5) comportant une partie d'ouverture intérieure ouverte (5H) ; d'un corps d'isolation thermique (R) disposé entre le boîtier extérieur (4) et le boîtier intérieur (5) ; d'une partie de production d'écoulement de gaz (30) ; et d'une pluralité de premiers conduits de gaz (12). Une zone chaude (P) dans laquelle un processus de mise sous pression est réalisé est formée à l'intérieur du boîtier intérieur (5). Pendant le processus de mise sous pression, un gaz de milieu de mise sous pression à basse température qui a été produit par la partie de production d'écoulement de gaz (30) et a traversé les premiers conduits de gaz (12) se déplace vers le haut dans un passage d'écoulement intérieur (L1) entre les boîtiers, puis s'écoule dans la zone chaude (P) à partir de la partie d'ouverture intérieure (5H). Même lorsque le gaz de milieu de mise sous pression fuit à partir du voisinage d'une partie de paroi inférieure (20) et s'écoule dans la zone chaude (P), l'uniformité thermique de la zone chaude (P) est maintenue.
(JA) 熱間等方圧加圧装置において、被処理物の加圧処理中のホットゾーンの均熱性を向上させる。HIP装置(100)は、外側開口部(4H)が開口された外側ケーシング(4)と、内側開口部(5H)が開口された内側ケーシング(5)と、外側ケーシング(4)と内側ケーシング(5)との間に配置された断熱体(R)と、ガス流発生部(30)と、複数の第1ガス導管(12)と、を備える。内側ケーシング(5)の内部に加圧処理を施すホットゾーン(P)が形成される。加圧処理時に、ガス流発生部(30)によって発生され第1ガス導管(12)を通過した低温の圧媒ガスは、ケーシング間内側流路(L1)を上昇した後、内側開口部(5H)からホットゾーン(P)に流入する。底壁部(20)の周辺から圧媒ガスがリークしホットゾーン(P)に流入した場合でも、ホットゾーン(P)の均熱性が維持される。
