につれ生産性向上、処理コスト低減の観点から冷却速度
の向上に対する要求が強まってきている。In recent years, the demand for processing various materials under high temperature and high pressure has increased, and HIP as a processing device has been attracting attention. HI
P is equipped with an inverted pot-shaped heat insulating layer in order to maintain the temperature of the pressure vessel below the predetermined design temperature, enable high-temperature treatment of up to 2000°C, and obtain good temperature distribution within the furnace. On the other hand, the heat insulating layer causes a long cooling time after heating. Particularly in recent years, as devices have become larger, there has been an increasing demand for improved cooling rates from the viewpoint of improving productivity and reducing processing costs.

公昭５９−１４７１２号公報）。Since high-pressure gas has high density and low viscosity, it is known that the cooling rate can be increased by flowing the gas.As shown in FIG. 5, a fan 16 is placed at the bottom of the pressure vessel 2. , attempts have been made to generate forced convection of pressurized gas within the heat insulating layer 4 to improve the cooling rate (Japanese Patent Publication No. 14712/1983).
第５図の圧力容器内にファンを設置する方法によっても
相応の効果を上げることは可能であるが、以下のような
欠点がある。Although it is possible to obtain a corresponding effect by installing a fan inside the pressure vessel as shown in FIG. 5, it has the following drawbacks.
（１）ファンは、可動部品が多く、信頼性に欠ける。(1) Fans have many moving parts and lack reliability.
（２）ファン方式は冷却能力が比較的小さく、生産設備
として使用される中・大型ＨＩＰの冷却装置としては不

(4) Furthermore, in order to maintain cooling capacity for a long time, a flow path must be formed between the lower part of the heat insulating layer and the shielding plate, and a flow path must be formed between the heat insulating layer and the inner surface of the pressure vessel.

、炉内がよく混合され炉内温度が均一化する。An embodiment equipped with only a nozzle will be described below with reference to FIG. The gas in the gas cylinder 11 is pressurized by the gas compressor 10 and reaches the nozzle 9 through the communication hole 17 penetrating the lower lid 3 of the pressure vessel 2 . The diameter of the nozzle 90 is narrowed, and the gas is blown out from the nozzle 9 vigorously at high speed. The gas blown out from the nozzle 9 passes through the blown gas guide pipe 7, reaches the upper part of the inner surface of the heat insulating layer 4, and then diffuses into the furnace. As a result, the high-density low-temperature gas spreads in the upper part of the furnace, and intense convection immediately occurs with the low-density high-temperature gas inside the furnace. As a result, the convection heat transfer coefficient within the furnace increases, and the inside of the furnace is well mixed, making the temperature inside the furnace uniform.

If the lower atmospheric temperature rises and there is a risk of adversely affecting electrical equipment installed at the lower part of the pressure vessel 2, as shown in FIG.
By providing a shielding plate 12 that blocks other direct gas flow paths and providing a low-temperature pressure medium gas retention space 15 in the lower part of the pressure vessel 2, the amount of gas blown out from within the heat insulating layer 4 is suppressed as much as possible. At this time, if the low temperature gas blown into the heat insulating layer 4 expands and the pressure inside the heat insulating layer 4 increases, the inner surface of the pressure vessel 2 and the heat insulating layer will be 4 Blow out the pressurized gas between the outer surface and the outer surface.

とともに、炉内がよく混合され炉内温度が均一化する。Although the above method also considerably improves the cooling rate inside the device,
An embodiment in which the cooling rate can be further improved will be described with reference to FIG. In this embodiment, two stages of injectors 13-1 and 13-2 are arranged at appropriate intervals on the ejection side of the nozzle 9 and within the low-temperature pressure medium gas retention space 15. The gas in the gas cylinder 11 is pressurized by the gas compressor 10 and reaches the nozzle 9 through the communication hole 17 penetrating the lower lid 3 of the pressure vessel 2 (see FIG. 2). The diameter of the nozzle 9 is narrowed, and the gas is blown out from the nozzle 9 with great force at high speed. The gas blown out from the nozzle 9 entrains the low-temperature and high-density gas in the low-temperature pressure medium gas retention space 15 at the bottom of the pressure vessel 2, and then flows into the injector (first stage) 13-1.
to go into. At this time, the gas flow rate passing through the injector (first stage) 13-1 has significantly increased compared to the amount of gas pressurized by the gas compressor 10. This gas is transferred to the injector (second stage) 13-2 while drawing in a larger amount of low-temperature gas.
be led to. The gas whose flow rate has been greatly increased in this way passes through the ejected gas guide pipe 7 from the injector (second stage) 13-2, and is forcefully blown out onto the upper inner surface of the heat insulating layer 4. As a result, the high-density low-temperature gas spreads in the upper part of the furnace, and intense convection immediately occurs with the low-density high-temperature gas inside the furnace. As a result, the convection heat transfer coefficient within the furnace increases, and the inside of the furnace is well mixed, making the temperature inside the furnace uniform.

設ける。In order to maintain the above-mentioned cooling capacity for a long time, a flow path 7 is provided between the lower part of the heat insulating layer 4 and the shielding plate 12, as shown in FIG.
-1, the gas is actively blown out from the bottom of the heat insulating layer 4. Furthermore, a gas cooling channel 14 is provided in which the gas blown out from the channel 7-1 exchanges heat with the low-temperature pressure medium gas existing between the inner surface of the pressure vessel 2 and between the inner surface of the pressure vessel 2 and the outer surface of the heat insulating layer 4.

A gas loop is formed from gas cooling channel 14 to low temperature gas retention space 15, low temperature pressure medium gas is successively supplied to low temperature gas retention space 15, and the gas temperature in low temperature gas retention space 15 is extremely low. Rapid cooling can be performed continuously without any rise.
