添付図面について概説する。 Since such HIP processing is carried out in an atmosphere of high temperature and pressure, it requires a special structure and is expensive.
Using a HIP device, it was necessary to spend a long time raising the temperature, increasing the pressure, lowering the temperature, and lowering the pressure, which had the disadvantage of extremely low productivity. In particular, it takes an extremely long time to cool down from a high temperature of over 1,000 degrees to a temperature at which the constituent materials of the equipment can withstand air oxidation, so how to shorten the cooling time is an important issue for rationalizing the technology. It was a challenge. In order to solve this problem, the present applicant has integrated a furnace structure consisting of a processing object storage section, a heating device surrounding it, and a heat insulating layer that encloses and covers the heating device together with the storage section. After charging the high-pressure vessel and subjecting it to HIP treatment, the above-mentioned furnace structure is taken out from the high-pressure vessel.
In Japanese Patent Application No. 170506/1984, we proposed a method that could significantly shorten the cooling time and improve the operating rate of the HIP furnace by transferring it to an auxiliary cooling station and cooling it. First, the proposed invention will be outlined with reference to the accompanying drawings.

理作業に取り掛ることができる。 As shown in FIG. 1a, conventionally, by attaching and detaching the lower lid 2 of the high-pressure container 1, only the object 3 placed on the lower lid was removed.
It was necessary to wait for the temperature inside the furnace to cool down to the oxidation-resistant temperature of the structural material inside the furnace before taking out the object to be processed. On the other hand, in the case of the HIP furnace shown in FIG. 1b, by removing the lower cover 2, the furnace consisting of the object to be processed 3 installed thereon, the heater 4, and the heat insulating layer 5 that encloses and covers them can be removed. After the structure is taken out in one piece and the pressure has dropped after the HIP process, the reactor structure is immediately taken out without waiting for the temperature to drop further, cooled at the cooling auxiliary station, and the high pressure The container is then ready for the next HIP process.

することができる。 In the HIP furnace, the furnace structure can be taken out as a whole by removing the lower cover 2 from the cylinder 1 as shown in FIG. 1b. On the other hand, the auxiliary stations 9, 9'..., as shown in FIG. 3, are mainly composed of a cap-shaped vessel 12 equipped with a refrigerant jacket 11 on the outer periphery, and have a capacity to completely accommodate the furnace structure. The lower lid 2 can be tightly fitted into the bottom opening of the vessel 12. In addition, the press frame 13 that clamps the upper lid and lower lid 2 of the high-pressure container 1 is mounted on a cart 14.
It is mounted on top and can reciprocate between an active position and a retracted position.

る。 According to such a system, the cooling process, which requires a long time after HIP treatment, is performed outside the high-pressure container.
The productivity of HIP equipment can be greatly improved. However, in the cooling auxiliary station shown in FIG. 3 used in the above system,
The furnace structure after HIP treatment is cooled to the required temperature by the action of the refrigerant jacket 11, but in this structure, a gas layer 15 is interposed between the refrigerant jacket 11 and the outer wall 14 of the heat insulating layer, Since this becomes a gas insulation layer, the cooling effect decreases, e.g.
It has even been observed that it takes about 20 hours to cool down from 1000°C to 150°C. Such a long cooling time does not balance with the HIP processing time, resulting in hand-holding time in the HIP furnace, and in order to eliminate hand-holding time, it is necessary to increase the number of cooling auxiliary stations. In any case
This is a major impediment to rationalizing the HIP processing system.

れる。 In FIG. 4, an object to be processed 3 is placed on the lower lid 2 of the high-pressure container via a sample stage 16, and a heater 4 surrounding the object to be processed and a heat insulating layer 5 enclosing and covering them are placed. There is basically no difference from the existing proposal explained in FIG. 1b in that the furnace structure is installed. Heat insulation layer 5
The casing is made of heat-resistant fibrous heat insulating material, such as ceramic fiber, filled in the mantle-shaped part formed by the inner and outer casings of the cap body, and these casings are made of stainless steel, heat-resistant ultra-thin material, etc., depending on the operating temperature. It is made of a heat-resistant material with low fluid permeability, such as an alloy or molybdenum. In particular, the outer casing constituting the heat insulating layer outer wall 14 is desired to have a stronger structure than the inner casing in order to increase fluid resistance.

１８，１８によつて離脱を防止される。 The above-mentioned furnace structure is inserted into the cylinder 17 constituting the auxiliary station, and the lower cover 2 is airtightly fitted into the lower opening of the cylinder 17, and is prevented from detaching by the locking devices 18, 18. be done.

保たれる。 The cylinder 17 has an inner wall and an outer wall 1 of the heat insulating layer.
The insulation layer 5 is coated with an appropriate gap 19 of about 10 to several tens of millimeters between the insulation layer 4 and the insulation layer 5, and is fitted with the insulation layer outer wall 14 near its upper and lower ends, and is secured by the upper rail and packing 20. Gap 19 is kept airtight.
かくして間隙１９は断熱層外壁１４を直接に取

る。 The cylinder 17 is most commonly shaped like a blind tube with its top closed, in which case the jacket may extend between the inner wall of the top of the cylinder and the top of the outer wall of the heat insulating layer. In the example shown in FIG. 5, the cylinder 17 has a cylindrical shape, and the gasket 20 near the lower end
In addition, its upper edge is fitted into the outer wall 14 of the heat insulating layer and sealed by an upper packing 24.

構造においては変わる所がない。 The above description has been about a type of cooling device in which the furnace structure is installed and removed through the lower opening of the cylinder 17, but it is of course also possible to use a type in which the furnace structure is installed and removed through the upper opening of the cylinder 17, as shown in FIG. There is no difference in the basic structure of the two.
次いで以下に本考案装置の作用について述べ
る。 Next, the operation of the device of the present invention will be described below.

８によつて固定される。 After the HIP treatment, the furnace structure taken out from the high pressure vessel 1 in a high temperature state is transported to the cooling auxiliary station 9, charged into the cylinder 17, and placed in the lower lid 2.
is fitted into the lower opening of the cylinder 7, and the locking device 1
8.

される。 Thus, a refrigerant jacket is formed in the gap 19 between the inner wall of the cylinder and the outer wall 14 of the heat insulating layer by the packing 20 and, in the case of a cylindrical cylinder, the packing 24. Thereafter, by opening the refrigerant supply valve, a refrigerant such as cooling water is introduced through the refrigerant supply port 21, flows to fill the refrigerant jacket, and is discharged from the refrigerant outlet 22. At this time, the refrigerant comes into direct contact with the heat insulating layer outer wall 14 and effectively removes heat. After being cooled to a predetermined temperature, the object 3 to be processed is taken out and transported to a product removal station.

４の表面を乾燥することは好ましいことである。 On the other hand, the refrigerant supply valve is closed, the supply of refrigerant is stopped, and the refrigerant remaining in the jacket is completely discharged from the refrigerant outlet 23. After that, by introducing hot air from the refrigerant supply port 21 and discharging it from the refrigerant outlet 22 by appropriate means such as switching a valve as necessary, the heat insulating layer outer wall 1 is heated.
It is preferable to dry the surface of 4.

からである。 In any case, it is required to completely drain the refrigerant remaining in the jacket and dry the surface of the heat insulating layer outer wall 14 before performing the next HIP process. This is because if the refrigerant, for example moisture, remains
This is because it mixes into inert gas such as argon gas during HIP processing and has a negative effect on heaters, products, etc.

るという驚くべき効果が認められた。 According to the device of this invention, cooling is performed with the outer wall of the heat insulating layer in direct contact with the refrigerant, so the cooling effect is dramatically improved. For example, it takes about 11 hours to cool from 1000℃ to 150℃. The surprising effect was that the cooling time could be reduced by about 40 to 45% compared to conventional cooling equipment.
