（産業上の利用分野）
本発明は熱間静水圧加圧（以下、ＨＩＰと略記する。）
装置に関し、詳しくは、ＨＩＰ処理後の冷却工程におい
て、その冷却時間を短縮してなお、ＨＩＰ処理体を均等
に冷却し得、もって稼動率の向上とＨＩＰ処理体の品質
安定化とを併せ可能とする上記ＨＩＰ装置ならびに同装
置を用いた冷却運転方法に関するものである。Detailed Description of the Invention (Industrial Application Field) The present invention relates to hot isostatic pressing (hereinafter abbreviated as HIP).
Regarding the equipment, in detail, in the cooling process after HIP processing, the cooling time can be shortened and the HIP processing object can be cooled evenly, thereby improving the operating rate and stabilizing the quality of the HIP processing object. The present invention relates to the above-mentioned HIP device and a cooling operation method using the same.
（従来の技術）
従来、ＨＩＰ装置は基本的に高圧容器と、上蓋および下
蓋とによって画成される高圧容器内の高圧室に断熱層と
、その内側ヒータに囲繞された処理空間、すなわち炉室
にて被処理体を高温・高圧処理することを基本構成とさ
れており、断熱性能、均熱性の重要なことより、これら
に関し種々の改良が提案されている。(Prior Art) Conventionally, HIP equipment basically includes a high-pressure chamber defined by a high-pressure container, an upper lid, and a lower lid, a heat insulating layer, and a processing space surrounded by a heater inside the high-pressure chamber, that is, a furnace. The basic configuration is to treat the object to be treated at high temperature and high pressure in a chamber, and various improvements have been proposed in relation to heat insulation performance and heat uniformity, which are important.
一方、このＨＩＰ処理は１サイクルに要する時間が長時
間に及ぶ難点があり、その重要な一因子として冷却工程
がある。On the other hand, this HIP process has the disadvantage that one cycle takes a long time, and one of the important factors is the cooling process.
このことは、ＨＩＰ装置の基本的な構成、即ちＨＩＰ処
理に要する高温なる熱から高圧容器の構成部材を保護す
るため、断熱層にて被処理体を含む炉室を被包し厳重に
熱遮閉した構成に起因するもので、その冷却工程におい
て断熱層に被包された炉室内の熱は、断熱層の熱遮断効
果により、外部に放散することを妨げられるからである
。This is due to the basic structure of the HIP equipment, which is to protect the components of the high-pressure vessel from the high-temperature heat required for HIP processing. This is due to the closed configuration, and the heat within the furnace chamber enclosed by the heat insulating layer during the cooling process is prevented from dissipating to the outside due to the heat blocking effect of the heat insulating layer.
そのため、断熱層と被処理体を含む炉室とを一体的に高
圧容器より取り出し、その冷却工程をＨｉｐ装置外に設
けた装置に賦課させてＨＩＰ装置の稼動率を高めるシス
テム、所謂、モジュラ−型ＨＩＰシステム等が開発され
ると共に、ＨＩＰ装置内の構成や構成部材等に種々の工
夫を加え、その冷却速度を高めんとする試みがなされて
いる。Therefore, a so-called modular system is developed, in which the heat insulating layer and the furnace chamber containing the object to be processed are taken out of the high-pressure container as a unit, and the cooling process is imposed on a device installed outside the Hip device, thereby increasing the operating rate of the HIP device. Along with the development of type HIP systems and the like, attempts have been made to improve the cooling rate of the HIP apparatus by making various improvements to the internal structure and components of the HIP apparatus.
一般に、熱伝達方式には対流、輻射、伝導の３つの形態
があることは周知であるが、ＨＩＰ装置の圧媒ガスを介
した高温・高圧下では特に対流が熱伝達の主体となる。Generally, it is well known that there are three types of heat transfer methods: convection, radiation, and conduction, but convection is the main type of heat transfer, especially under high temperature and high pressure via the pressure medium gas of a HIP device.
従って、ＨＩＰ装置において冷却時間の短縮を図るため
には対流する圧媒ガスの流れ、あるいはまた強制的に形
成した圧媒ガスの流れを利用するのが有効である。Therefore, in order to shorten the cooling time in a HIP device, it is effective to utilize a convection flow of pressure medium gas or a forced flow of pressure medium gas.
また、一方、冷却中、被処理体が上下方向に不均一に冷
却されると被処理体に歪が生じ、例えば薄物品のような
場合には処理後の被処理体が該歪によって使用に耐えな
くなるとか、また被処理体上下の冷却速度差により内外
組織に差を生じさせ、目的とする製品特性が部分的にし
か得られなくなるなどの品質低下を招来する。On the other hand, if the object to be processed is cooled unevenly in the vertical direction during cooling, distortion will occur in the object. In addition, the difference in the cooling rate between the upper and lower parts of the object to be processed causes a difference between the internal and external structures, leading to deterioration in quality such as the desired product characteristics being only partially obtained.
そして、上記欠点は被処理体が大型である程、またその
高さが高い程、助長され、顕著となる。The above disadvantages are exacerbated and become more noticeable as the object to be processed becomes larger and taller.
そこで叙上の如き事情を勘案し、圧媒ガスの流れを利用
して冷却速度を高めると共に、被処理体を均一に冷却す
る試みとして例えば第５図に示す実願昭６１−２４６７
６号装置が提案されるに至った。Therefore, in consideration of the above-mentioned circumstances, as an attempt to increase the cooling rate and uniformly cool the object to be processed using the flow of pressure medium gas, for example, Utility Model Application No. 61-2467 as shown in Fig. 5 was proposed.
The No. 6 device was proposed.

It is difficult to independently control the flow rate of the gas flow (A) flowing inside D and the flow rate of the gas flow (B) flowing down the inner wall of the high-pressure cylinder (1). For example, at the beginning of cooling, the gas temperature of the latter gas flow (B) is high, and the flow rate may be minimized to prevent excessive temperature rise of the inner surface of the upper lid (2) and the inner wall of the high-pressure cylinder (1), or the 10 must be opened and closed intermittently.

Therefore, whether the valve (11) is opened and closed intermittently or a variable throttle is provided in the valve (II) or the gas flow path (B) to reduce the flow rate, the circulation fan (31) and the motor A large load is applied to (25), which shortens the life of the motor or, in the worst case, causes damage to the motor due to tripping.

The method of lowering the temperature of the gas by installing a heat storage device in the space with the casing (8) and eliminating the need for opening and closing operations of a throttle or valve also reduces the effective area within the limited pressure vessel and reduces the QO of the furnace chamber. Furthermore, this method not only increases the thermal resistance but also reduces the flow rate of the two gases (A) and (B).

とした構成にある。(Means for Solving the Problems) That is, the features of the present invention for achieving the above object are as follows: firstly, in terms of mechanism, as shown in FIG. 1, in addition to the structure shown in FIG. In the cooling gas flow path, a valve (40) is provided at an essentially cold position inside the frame (4B), and a gas passageway (41) that can be opened and closed is provided to direct part or all of the cooling gas flow to the cooling gas. An apparatus is provided that enables circulation through a passage only in an essentially cold place, and claim 2 further provides a device in which a driving device for driving a coaxial stirring fan and a circulation fan in the apparatus is made variable speed. It has a more effective configuration.

The purpose of the latter is to achieve cooling efficiency, and the latter is particularly important when the cooling gas exiting from the upper passage of the outer casing is too high in temperature at the beginning of the cooling process, and when this passage is closed, the lower part of the cooling gas is The purpose is to open gas passages in essentially cold locations.

（４１）に設けられた弁（４０）によって調節する。(Function) According to the present invention, the gas flow (A) flowing inside the furnace chamber is adjusted by the rotation speed of the variable speed motor, while the flow rate of the gas flow (B) flowing down along the inner wall of the high-pressure cylinder is controlled by the lower gas flow. It is regulated by a valve (40) provided in the passage (41).
そこで、以下、冷却過程を説明すると、炉室内を一定の

数を増すことで充分、対応可能である。Therefore, to explain the cooling process below, in order to cool the inside of the furnace chamber at a constant rate, the two gas flows (8) and (B
) is required to be approximately constant over time. However, since the temperature difference between the two gas streams (A) and (B) decreases with time, the flow rate of the gas stream CB) must increase with time. On the other hand, in order to uniformly cool the inside of the furnace chamber, the flow rate of gas flow (8) must increase over time, but this increase in flow rate is generally smaller than the increase in flow rate of gas flow (B). It is possible to deal with this problem by increasing the rotation speed of the motor.
従って、ガス流（Ｂ）の流量が冷却終了付近でも十分な
量が得られるようファンおよび流路を設計し、それ以前
においては下部の１個又は複数個の弁（４０）を順次閉
じることによって流量を調節する。Therefore, the fan and flow path are designed so that a sufficient flow rate of the gas flow (B) can be obtained even near the end of cooling, and before that, one or more valves (40) at the bottom are sequentially closed. Adjust the flow rate.

返している間、開放したままとすることもある。Next, at the beginning of cooling, the gas flow (B) is at a high temperature, so the upper valve (usually designed to open and close repeatedly, but at this time, the valve 01) is closed. Open the lower valve (40) to avoid overloading the motor. Then, when valve 01) opens, valve (40)
Close. Note that the valve (40) may remain open while the valve (11) repeats opening and closing.

床下部の空間に還戻する。Thus, when the stirring fan (24) is activated by the motor (25), the adiabatic hearth (6) blooms (26) and the opening provided in the lower surface of the storage casing (22) for the object to be treated (7) is caused. (27), the gas inside the furnace passes through the object to be treated (7) and the storage casing (22) as shown in the arrow view (A) in Figure 1.
), heat is taken away through the side surface of the object to be processed (7), and the cooling is reversed at the top of the furnace chamber c2 (Il) and passed through the heat insulating layer at the inner casing (4) of the heat insulating layer (4). The gas flows down while exchanging heat with the gas, and the pedestal (
21) through the opening (28) into the space below the hearth where the fan (24) is housed.

る。On the other hand, it passes through the insulation N (4) and removes heat, and the high pressure cylinder (1
) The stirring cooling fan, which cools the air while flowing down along the inner wall of the furnace, passes through the opening (32) provided in the lower cover (3) as shown by the arrow (B), separately from the gas in the furnace shown in FIG. The air flows into the fan section by the action of the circulation fan (31), and is forcibly circulated through the opening (33) at the bottom of the partition plate (34) toward the opening θ0 at the bottom of the heat insulating layer. At this time, the flow rate of this gas flow (B) flows as another gas flow (B') by opening and closing the lower valve (40), and the iJR clause is established.

（Ｂ）の流量は時間と共に多くならなければならない。That is, in order to cool the inside of the furnace chamber Q[D at a constant rate,
It is necessary that the amount of heat exchanged between the gas streams (A) and (B) is approximately constant with respect to time. However, typically both gas streams (A
) Since the temperature difference in (B) decreases with time, the flow rate of the gas stream (B) must increase with time.

Although the flow rate of the gas flow (B) must increase with time, this flow rate increase is generally smaller than the flow rate increase of the gas flow (B), and can be handled by increasing the rotational speed of the motor (25).
従って、ガス流ＣＢ）の流量が冷却終了付近でも十分な

順次閉じることによって流量を調節する。Therefore, the fan (31) and the flow path are designed so that a sufficient flow rate of the gas flow CB) can be obtained even near the end of cooling.
Before that, the flow rate is regulated by sequentially closing one or more valves (40).

必要とするガス流（Ｂ）の流量による。しかし、後者の
方が一般に流量が少ない。In addition, at the initial stage of cooling, the temperature of the gas flow (B) is high, and therefore the valve θl) is normally configured to repeatedly open and close in order to prevent the inner wall of the high pressure cylinder (1) from rising excessively. However, at this time, as shown in Figure 2, the valve (1
1) is closed, the valve (40) is opened, and the gas flow by the circulation fan (31) is made as shown by the arrow (B') in the figure, thereby applying an overload to the motor (25). There can be no. In addition, the valve (when the river opens, close the valve (40). Alternatively, the valve (40) may be left open while the valve (11) repeats opening and closing; whichever method is chosen is necessary. It depends on the flow rate of the gas flow (B). However, the latter generally has a lower flow rate.
次に上記第１図、第２図の例において弁（４０）を同心
円状等間隔に８個配置し冷却を行う場合の運転例を第３
図に示す。Next, a third example of operation in which cooling is performed by arranging eight valves (40) concentrically at equal intervals in the example shown in FIGS. 1 and 2 above is shown.

如く一定の冷却速度を確保する。That is, after cooling starts, valve 01) is repeatedly opened and closed for a while, and after the temperature of the gas flow (B) decreases and valve (11) is left open, valves (40) are opened symmetrically in four and six valves. , 8, and the flow rate of the closed gas flow (B) is increased one after another to ensure a constant cooling rate as shown in the upper diagram.
なお、均熱性については炉室向上部と下部の温度を測定
し、その差が一定範囲となるようモータ（２５）の回転
数を増加することによって達成される。Note that thermal uniformity is achieved by measuring the temperatures of the upper and lower parts of the furnace chamber, and increasing the rotational speed of the motor (25) so that the difference between them is within a certain range.

おかれるためＤＣソレノイドなどが用いられる。Note that the valve (40) only needs to be small in shape, and a DC solenoid or the like is used since it is basically placed in a low temperature region, usually in a region of about 100°C.
そして、この弁（観）の駆動機構は下蓋側であっても、

。In this case, unlike in Fig. 1, the flow of the gas stream (B) is driven by a circulation fan (31) located at the lower part of the furnace chamber, where it comes into direct contact with the gas stream (A), exchanges heat, and mixes. While the flow rises inside the storage casing (22), heat is taken away from the object to be processed (7), and some of the heat is absorbed into the upper passage 05), (lω
It becomes a gas flow (B) and radiates heat to the high pressure cylinder (1), with most of the remaining heat flowing into the furnace chamber C! It descends through Φ and becomes a gas flow (A).

め熱抵抗が小さく、より冷却速度は大となる。In particular, in the apparatus proposed in Utility Model Application No. 61-24676, the heat of the object to be treated is transmitted from the gas flow (A) to the inner inverted cup-shaped casing to the reflux gas flow (B) to the high-pressure cylinder. The thermal resistance is large (although in the present invention, the heat of the object to be processed is transferred from the gas flow (A) to the gas flow (B) to the high-pressure cylinder, so the thermal resistance is small and the cooling rate is higher.

る。Moreover, in the case of the present invention, the direction of the gas flow (B) is the same as the direction of natural convection in which cold gas is warmed and rises.
When the same flow rate is forced to flow back, it has the advantage of requiring less driving force than flowing in the opposite direction, and the gas flowing to the bottom of the furnace is already cooled by the cylindrical wall, and the bottom surface of the top lid is There is also the advantage that heat dissipation through the top lid can be carried out efficiently because of the presence of relatively high temperature gas.

By closing, it is possible to sequentially adjust the gas flow, and at the beginning of cooling, the gas flow by the circulation fan can be made as shown in (B') to prevent overloading the motor.
