Claims

[Scope of utility model registration request]

In the high-pressure vessel 1, a heat insulating layer 4 made of at least two overlapping inverted cup-shaped casings 5 and 6, the inner and outer sides, is arranged to form a furnace chamber 8, and a heater 11 and a temperature measuring means 12 are installed in the furnace chamber 8. A high-pressure gas pressure medium is introduced into the high-pressure vessel 1, the gas pressure medium in the furnace chamber 8 is heated, and the high-temperature and high-pressure gas pressure medium is applied to the workpiece 10 to perform hot heating, etc. After performing the direction pressure treatment, the opening/closing means 18, 20 of the top plate portion 4a of the heat insulating layer 4
In a hot isostatic pressurizing device that cools the inside of the furnace chamber 8 by opening the furnace and circulating a high-temperature gas pressure medium, the inner space 14 of the heat insulating layer 4 is formed in the lower part of the outer casing 6. Space 13 on the outside high pressure vessel side
The opening/closing means 18 and 20 of the top plate portion 4a of the heat insulating layer 4 connect the furnace chamber 8 and the heat insulating layer 4.
The first opening and closing between the space 13 on the outside high-pressure vessel side and the
It has an opening/closing means 18 and a second opening/closing means 20 that opens and closes between the internal space 14 of the heat insulating layer 4 and the space 13 on the high pressure vessel side outside the heat insulating layer 4, and according to the temperature measured by the temperature measuring means 12. A hot isostatic pressurizing device characterized in that it is equipped with an opening/closing control means 29 that opens the second opening/closing means 20 when the temperature is high and the first opening/closing means 18 when the temperature is low.
