In FIG. 4, (21) is a high-pressure container, and this high-pressure container (21) has a cylindrical container body (22) and a sealing material (28 It is composed of an upper lid (23) and a lower lid (24) which are hermetically sealed with each other. The upper lid (23) is also provided with a pressure medium introduction hole (23a) for introducing a pressure medium fluid. Further, in this high-pressure container (21), an insulating layer (26) formed in an inverted cup shape is suspended and supported by an upper lid (23), and a gap is formed between the inner wall surface of the high-pressure container (21). It is arranged with. A heater (25) is provided inside the heat insulating layer (26), and the heater (25) is connected to the upper lid (23) via a conductor (29a) penetrating the upper portion of the heat insulating layer (26). It is connected to an electrode (29) that is electrically insulated and airtight. Further, a columnar shape is formed below the heat insulating layer (25), and the upper opening of the heat insulating layer (25) closes the lower opening of the heat insulating layer (25) so that gas can flow therethrough. A lower heat insulating layer (27) that plays a role is disposed by being supported by the lower lid (24), whereby a heat insulating layer (26) and a lower heat insulating layer (27) are provided in the high pressure vessel (21). Forming a processing chamber (30) defined by.
【０００４】 そして、このＨＩＰ装置では、高圧容器(21)から下蓋(24)と一体に取り出され た下部断熱層(27)上に被処理体(M) を載置し、それらを一体に高圧容器(21)内に 挿入することで、被処理体(M) を処理室(30)内に装入し、しかる後、その高圧容 器(1) 内に、通常数100kgf/cm2から2600kgf/cm2 の高圧とされたアルゴンガス等 の圧媒流体を導入すると共に、ヒータ(25)に入力して数 100℃から2600℃の高温 に加熱することで、処理室(30)内に装入した被処理体(M) に、高温高圧の圧媒流 体を作用させ、その高い等方圧と高温の相乗効果によって、粉末材料の加圧焼結 や拡散接合、または金属材と粉末材料および異種金属材同士等の複合化のための 熱間加圧処理を行う。 この種のＨＩＰ装置では、被処理体を別途用意した予熱炉で予熱した後、下蓋 と一体の下部断熱層上に載置して、高圧容器下方から処理室内に装入することで 、高圧容器内での加熱時間を短縮し、もって処理サイクルタイムを短縮して稼働 効率を向上させることができる。In this HIP device, the object to be treated (M) is placed on the lower heat insulating layer (27) taken out integrally with the lower lid (24) from the high pressure vessel (21), and they are integrated together. By inserting it into the high-pressure container (21), the object to be treated (M) is loaded into the processing chamber (30), and then, in the high-pressure container (1), usually several hundred kgf / cm 2 By introducing a pressure fluid such as argon gas at a high pressure of 2600 kgf / cm 2 and inputting it to the heater (25) to heat it to a high temperature of several 100 ° C. to 2600 ° C., the inside of the processing chamber (30) is A high-temperature and high-pressure pressure medium is applied to the charged object (M), and the high isotropic pressure and high temperature synergistic effects cause pressure sintering and diffusion bonding of powder materials, or metal and powder. Hot pressurization is performed to combine materials and different metal materials. In this type of HIP device, after preheating the object to be processed in a separately prepared preheating furnace, it is placed on the lower heat insulating layer integrated with the lower lid, and is loaded into the processing chamber from below the high pressure container. It is possible to shorten the heating time in the container, thereby shortening the processing cycle time and improving the operating efficiency.
【０００５】 しかし、このＨＩＰ装置では、高圧容器での加熱時間を短縮して稼働効率の向 上が図れるものの、予熱後の被処理体の搬送が大気中で行われるため、その搬送 過程での放熱による熱損失が大きいという問題があり、更に、予熱後の高温な被 処理体を、下蓋と一体の下部断熱層上に載置して、高圧容器内に挿入する際に、 被処理体からの放熱により高圧容器の下部内壁面が過熱され、その過熱により、 下蓋との間を密封するシール材が損傷を受けるだけでなく、高圧容器の耐用寿命 をも低下させるという問題があった。However, in this HIP device, although the heating time in the high-pressure vessel can be shortened and the operating efficiency can be improved, the object to be treated after preheating is conveyed in the atmosphere, and therefore, in the conveying process. There is a problem that heat loss due to heat dissipation is large.In addition, when the preheated high temperature object is placed on the lower heat insulating layer integrated with the lower lid and inserted into the high pressure container, the object to be processed is The inner wall surface of the lower part of the high-pressure container is overheated due to the heat radiation from the container, and this overheating not only damages the sealing material that seals the lower lid, but also shortens the useful life of the high-pressure container. .
【０００６】 そこで、このような問題点を解決すべく各方面から種々の改善検討が加えられ 、例えば、特公昭63-26839号では、下部断熱層だけでなく、その上部の断熱層お よびヒータも、下蓋と一体的に高圧容器外に取出し可能に設け、これによって処 理サイクルタイムを短縮する一方、予熱された被処理体の装入に際する高圧容器 への熱影響を防止する技術が提案されている。[0006] Therefore, in order to solve such a problem, various improvement studies have been added from various fields. For example, in Japanese Examined Patent Publication No. 63-26839, not only the lower heat insulating layer but also the upper heat insulating layer and the heater are provided. Is also integrated with the lower lid so that it can be taken out of the high-pressure container, thereby shortening the processing cycle time and preventing thermal effects on the high-pressure container when loading preheated objects. Is proposed.
【０００７】 〔図３〕は、上記技術（特公昭63-26839号）に係るＨＩＰ装置の概要構成を示 す正断面図である。なお、このＨＩＰ装置は、処理室構成部の支持関係が異なる 点を除いて、主体構成部は〔図４〕に示したものと基本的に同様であるので、こ こでは等価な各部に同符号を付して説明を省略し、差異点のみを要約説明する。FIG. 3 is a front sectional view showing a schematic configuration of a HIP device according to the above technique (Japanese Patent Publication No. 63-26839). The main component of this HIP device is basically the same as that shown in FIG. 4 except that the supporting relation of the processing chamber components is different. Only the differences will be summarized.
【０００８】 〔図３〕に示すＨＩＰ装置では、倒立コップ状の断熱層(26)が、下蓋(24)上に 直接的に載置されて支持される一方、この断熱層(26)内側のヒータ(25)は、金属 性円筒(31)内に電気絶縁状態で保持されると共に、その金属性円筒(31)を介して 断熱層(26)とは独立して下蓋(24)に連結支持され、かつ、下蓋(24)に電気的絶縁 かつ気密状態に設けられた電極(29') に接続されている。In the HIP device shown in FIG. 3, the inverted cup-shaped heat insulating layer (26) is directly placed on and supported by the lower lid (24) while the inside of the heat insulating layer (26) is supported. The heater (25) is held in an electrically insulated state in the metallic cylinder (31), and is separated from the heat insulating layer (26) via the metallic cylinder (31) to the lower lid (24). It is connected and supported, and is connected to an electrode (29 ') provided on the lower lid (24) in an electrically insulated and airtight state.
【０００９】 そして、このＨＩＰ装置では、下部断熱層(27)だけでなく、断熱層(26)および ヒータ(25)も下蓋(24)と一体的に高圧容器(21)外に取出し、その外部において、 断熱層(26)を持ち上げて処理室(30)を開放し、処理済の被処理体(M) を取出す。 次いで、新たな被処理体(M) を、ヒータ(25)の内側となる下部断熱層(27)上に 載置すると共に、断熱層(26)を再び下蓋(24)上に載置して処理室(30)を遮蔽した 後、電極(29') を通じてヒータ(25)に入力して、処理室(20)内の被処理体(M) を 所定の温度まで予熱し、しかる後、これらを下蓋(24)と一体的に、高圧容器(21) 内に挿入して、高温高圧下での等方的な加圧処理を行う。In this HIP device, not only the lower heat insulating layer (27) but also the heat insulating layer (26) and the heater (25) are taken out of the high pressure container (21) integrally with the lower lid (24), Outside, the heat insulating layer (26) is lifted to open the processing chamber (30), and the processed object (M) is taken out. Next, a new object (M) is placed on the lower heat insulating layer (27) inside the heater (25), and the heat insulating layer (26) is placed on the lower lid (24) again. After shielding the treatment chamber (30) with the electrode (29 '), input to the heater (25) to preheat the object to be treated (M) in the treatment chamber (20) to a predetermined temperature. These are integrally inserted into the high pressure container (21) together with the lower lid (24) to perform isotropic pressure treatment under high temperature and high pressure.
【００１０】 このＨＩＰ装置では、上記のように高圧容器外で、被処理体を自己完結的に予 熱できるので、別途に予熱炉等の加熱手段を設ける必要がなく、更に予熱後も、 被処理体を断熱層と下部断熱層で画成された処理室内に装入したままで、高圧容 器内に挿入できるので、予熱後の被処理体の放熱による熱損失と、高圧容器の下 部内壁面への熱影響を確実に防止することができ、よって短いサイクルタイムの 加圧処理を、装置各部への悪影響を与えることなく行うことができる。In this HIP device, since the object to be treated can be preheated in a self-contained manner outside the high-pressure container as described above, it is not necessary to separately provide a heating means such as a preheating furnace, and even after preheating, Since the treatment object can be inserted into the high-pressure container while it is still loaded in the treatment chamber defined by the heat insulation layer and the lower heat insulation layer, the heat loss due to the heat radiation of the treatment object after preheating and the lower part of the high pressure container It is possible to reliably prevent the influence of heat on the wall surface, and thus it is possible to perform pressurization processing with a short cycle time without adversely affecting each part of the device.
【００１１】[0011]
しかし、上記ＨＩＰ装置（特公昭63-26839号）では、述上の効果により安定し た加圧処理が継続できるものの、次のような問題点を内在している。 すなわち、別途の予熱炉等によらずに、短いサイクルタイムの加圧処理に対応 するには、ヒータ(25)、断熱層(26)、下部断熱層(27)および下蓋(24)を一体的に 備えるセットを、少なくとも２組以上準備して、それらを交互に使用して被処理 体(M) を個別に予熱する必要があり、そのための設備費が比較的多く要する。 また、予熱手段もヒータ(25)に限定されるので、その予熱効率の向上にある限 界が生じる。例えば、階段的な昇温が必要とされる同種の被処理体を連続的に加 圧処理する場合には、連続加熱炉等を用いる方が熱効率に優れ、また急激な昇温 が許容される被処理体の場合では、燃焼ガス等による加熱の方が有利となる。 また、被処理体(M) を装脱するについては、断熱層(26)の上下昇させると共に 、ヒータ(25)の内側となる下部断熱層(27)上から装脱するので、つまり上方から しか被処理体(M) の装脱ができないので、そのハンドリングの作業性が悪い。 However, in the above HIP device (Japanese Patent Publication No. 63-26839), although stable pressure treatment can be continued due to the above-mentioned effects, the following problems are inherent. That is, the heater (25), the heat insulating layer (26), the lower heat insulating layer (27), and the lower lid (24) are integrated in order to cope with pressurizing treatment with a short cycle time without using a separate preheating furnace or the like. It is necessary to prepare at least two or more sets for the purpose of pretreatment, and to use them alternately to preheat the object to be treated (M) individually, which requires a relatively large equipment cost. Further, since the preheating means is also limited to the heater (25), there is a limit in improving the preheating efficiency. For example, in the case of continuously applying pressure treatment to the same type of object that requires a stepwise temperature increase, it is better to use a continuous heating furnace or the like because the thermal efficiency is superior and a rapid temperature rise is allowed. In the case of the object to be treated, heating with combustion gas or the like is more advantageous. In addition, when loading or unloading the object to be treated (M), the heat insulating layer (26) is moved up and down and the lower heat insulating layer (27) inside the heater (25) is loaded and unloaded, that is, from above. However, since the object to be processed (M) can be attached and detached, the workability of its handling is poor.
【００１２】 本考案は、上記従来技術の問題点を解消するためになされたもので、別途の予 熱炉等で予熱した被処理体を、下蓋と一体の下部断熱層上に載置して高圧容器下 方から処理室内に装脱し、高圧容器内での加熱時間を短縮して稼働効率を高める ことができ、しかも、高圧容器への搬送および挿入の過程での被処理体の放熱を 、簡易な構成のもとで抑えて熱損失を低減できると共に、高圧容器の下部内周面 の過熱を防止することができ、また被処理体の下部断熱層上への装脱が容易であ り、よって効率の良い加圧処理が達成できると共に、高圧容器およびシール部へ の熱影響を低めて安定した稼働を継続できるＨＩＰ装置の提供を目的とする。The present invention has been made in order to solve the above-mentioned problems of the prior art, in which an object to be treated which has been preheated in a separate preheating furnace or the like is placed on the lower heat insulating layer integrated with the lower lid. By loading and unloading from below the high-pressure container into the processing chamber, it is possible to shorten the heating time in the high-pressure container and improve operating efficiency, and also to dissipate heat from the object to be processed during the process of transfer and insertion into the high-pressure container. In addition, it is possible to suppress heat loss with a simple structure and prevent overheating of the lower inner peripheral surface of the high-pressure container, and it is easy to load and unload the object to be processed onto the lower heat-insulating layer. Therefore, it is an object of the present invention to provide a HIP device that can achieve efficient pressurization processing and can reduce the thermal influence on the high-pressure container and the seal portion to continue stable operation.

Can be raised. Further, the heat insulating heat insulating tube (9) is located between the lower end of the heat insulating layer (6) and the lower lid (4) when inserted into the high pressure vessel (1) together with the lower lid (4), and Since the high temperature inside (10) can not be directly received and can be stored in the lower part of the inside where the temperature is relatively low, the heat insulation cylinder (9) is overheated during the high temperature pressurization of the object (M) to be processed. Can be avoided. Further, even when the processed object (M) after pressurizing treatment is taken out at a high temperature, the heat insulation and heat insulation cylinder (9) extends autonomously and shields heat dissipation from the processed object (M). As with the insertion, overheating of the lower inner surface of the high-pressure container (1) can be prevented.

【００３２】 以上に述べたように、本考案に係る上記２実施のＨＩＰ装置では、別途の予熱 炉等で予熱した被処理体を、下蓋と一体の下部断熱層上に載置して高圧容器下方 から処理室内に装脱し、高圧容器内での加熱時間を短縮して稼働効率を高めるこ とができ、しかも、高圧容器への搬送および挿入の過程での被処理体の放熱を、 簡易な構成のもとで抑えて熱損失を低減できると共に、高圧容器の下部内周面の 過熱を防止することができ、また被処理体の下部断熱層上への装脱が容易であり 、よって効率の良い加圧処理が達成できると共に、高圧容器およびシール部への 熱影響を低めて安定した稼働を継続することができる。As described above, in the HIP device according to the above-described second embodiment of the present invention, the object preheated in a separate preheating furnace or the like is placed on the lower heat insulating layer integrated with the lower lid, and high pressure is applied. By loading and unloading from the bottom of the container into the processing chamber, it is possible to shorten the heating time in the high-pressure container and improve operating efficiency, and moreover, to easily radiate heat from the object to be processed during the transfer and insertion into the high-pressure container. With this structure, heat loss can be suppressed and heat can be prevented from being overheated on the lower inner peripheral surface of the high-pressure container, and it is easy to load and unload the object to be treated on the lower heat-insulating layer. A good pressure treatment can be achieved, and the thermal influence on the high-pressure container and the seal part can be reduced to continue stable operation.

It is also possible to provide a simple lock mechanism on each of the short cylinders constituting the above and to expand and contract by an external force. The heat insulating and heat insulating tube was made of stainless steel, because it has a low thermal conductivity and an excellent heat insulating and heat insulating effect. However, it goes without saying that other materials may be used as long as they can obtain both low thermal conductivity and structural strength.
