Detailed Description of the Invention

  The present invention relates to a heat-resistant pressure device. More specifically, the present invention relates to a high-temperature and high-pressure generator capable of generating a high-temperature and high-pressure atmosphere equipped with a heat-resistant pressure vessel that can withstand an internal temperature of 1000 ° C. or higher and withstand an internal pressure of 50 MPaG or higher. This equipment is particularly useful for the development and improvement of alloys, composite metals, and various new materials, including aluminum, copper, iron, and other various metal materials, and for various metal sintering operations. Can be used.

  Up to now, casting equipment etc. for forming composite products with enhanced ductility, toughness, rigidity, wear resistance, etc. of the metal by melting metal such as aluminum at high temperature and adding ceramic particles etc. to it Is known as shown in FIG. In such a casting apparatus 10, a pressure made of steel or the like so that the process for melting the metal and the process for separating the inside of the mold and the inside of the pressure vessel by the fluid can be performed in one process. A chamber 16 for melting a raw material, that is, a molten material 18 is disposed in the container 12, and a fluid communicates with the chamber 16 and a mold 20 made of, for example, stainless steel via a passage 24.

  However, in the apparatus known so far, the temperature inside the container is limited to about 650 to 700 ° C. at the highest in order to perform a melting operation of a metal such as aluminum, and the pressure inside the container is About 1 MPaG. However, in order to create a composite product of more metals and perform various metallurgical methods in a thorough and rapid manner, it has a structure in which the temperature inside the container can withstand a high temperature of about 1000 ° C., for example. At the same time, the development of a device having a structure capable of withstanding a very high internal pressure of, for example, about 50 MPaG has been particularly eagerly desired by those skilled in the art.

  However, at present, due to the regulations of the High Pressure Gas Safety Law, the gas to be used and the container for storing the gas are severely restricted in terms of temperature and pressure. As a result, for example, in order to elucidate the metallurgical characteristics of a specific metal or the physicochemical characteristics of various alloys, the metal is specified under the above-mentioned predetermined temperature (for example, 1000 ° C.) and predetermined pressure (for example, 50 MPaG). Even if we intend to conduct metallurgical experiments, there is a problem that an apparatus that forms such an atmosphere is extremely expensive to manufacture an apparatus that actually meets such requirements by the high-pressure gas safety method. There is. As a result, the current situation is that the temperature and pressure conditions in physicochemical equipment for metals in many laboratories must be limited.

  Therefore, the present invention touches the regulations of the High Pressure Gas Safety Law by generating a very high temperature of, for example, about 1000 ° C. and using water without compressibility at a very high pressure of about 50 MPaG. Therefore, an object of the present invention is to realize an apparatus that can be formed inexpensively, easily and extremely safely. This is because the development and improvement of a new metal material can be executed at a very low cost.

  In order to solve the above-mentioned problems, the present invention is arranged in an enclosure 42 having one open end, a lid 43 that hermetically seals the open end of the enclosure 42, and the enclosure 42. One end-open heat-resistant pressure vessel 35, a sealing plug 36 hermetically sealing the open end of the vessel 35, heating means 38 disposed around the vessel 35 in the enclosure 42, and a vessel in the enclosure 42 35 and the heat-resistant cement 39 which surrounds the heating means 38, the heat-resistant waterproof means 40 which surrounds the container 35, the heat-resistant cement 39 and the heating means 38 in a liquid-tight state in the enclosure 42, and the container 35. A gas supply source 47 for supplying the processing gas to the water, a water supply pump 57 for filling the internal space 41 of the enclosure 42 with water except for a portion surrounded by the waterproof means 40, and the pressure and water supply of the gas supply source 47 pump 7, the gas supply source 47, the accumulator 45, the gas supply pipes 46, 44 connecting the accumulator 45 and the container 35, the water supply pump 57, the accumulator 45, and the accumulator 45. The gas flowing out from the accumulator 45 is supplied to the container 35 side in the pipes connecting the water supply pipes 61 and 56 connecting the radiator 45 and the internal space 41 of the enclosure 42 and the gas supply source 47 and the accumulator 45. Is in a pipe connecting the on-off valve 51 disposed at a position where the gas supply source 47 is blocked to the gas supply source 47, the water supply pump 57, and the accumulator 45, and the water supplied from the accumulator 45 is supplied to the enclosure 42 side. A high-temperature and high-pressure generator comprising an on-off valve 62 which is disposed at a position where it is supplied but blocked to the feed water pump 57 side is proposed. To.

  The present invention uses the above-described means to use a water having no compressibility at a very high temperature of about 1000 ° C. and a very high pressure of about 50 MPaG, without touching the regulations of the High Pressure Gas Safety Law. It has become possible to provide an apparatus that can be formed inexpensively, easily and extremely safely. This made it possible to develop and improve new metal materials at a very low cost. Furthermore, this apparatus enables the elucidation of the metallurgical properties of specific metals or the physicochemical properties of various alloys under very high temperatures of about 1000 ° C. and extremely high pressures of about 50 MPaG, or It was possible to conduct specific metallurgical experiments under high temperature and pressure.

  FIG. 1 is an overall view showing a specific example of the present apparatus 34. In the figure, reference numeral 35 denotes a heat resistant pressure vessel. The container 35 is preferably made of a material that is physically and chemically stable and rich in chemical resistance, such as quartz or ceramic. The upper end of the container 35 is open, and one or more kinds of solids, powders, liquids, etc. as materials to be tested are supplied from the open upper end. The container 35 has a volume enough to meet such a demand.

  The open upper end of the container 35 is hermetically sealed with a sealing plug 36 having a generally T-shaped cross section. The hermetic plug 36 is formed of a physically and chemically stable, compression-resistant gas-impermeable material (for example, ceramics or quartz glass), and blocks the flow of gas as well as solid and liquid. Thus, the inside of the container 35 is configured to be surely cut off from the atmosphere outside the container 35. In order to ensure this blocking, a sealing ring 36 is provided with a 0-ring 37 for sealing between the container 35 and the container 35. A heating means 38 made of a ceramic fiber heater or the like is disposed around the outer periphery of the container 35 (in the illustrated example, disposed in a spiral shape), whereby the interior of the container 35 is heated. This heating means is connected to an external power source via a conducting wire.

  Further, an insulating heat-resistant cement 39 is disposed around the container 35 and the heating means 38 so as to surround it. This cement 39 is the neck of the container and surrounds most of it except for the upper part with which the sealing plug 36 is engaged. This prevents the hollow portion of the container 35 from receiving a pressure of, for example, 50 MPaG directly from the outside. Further, a heat-resistant waterproofing means 40 made of heat-resistant waterproof rubber or the like surrounds the cement 39 in a liquid-tight state. A container 35 surrounded by a heat-resistant waterproofing means 40, a heating means 38 surrounding the container 35, and a heat-resistant cement 39 surrounding the heating means 38 are inserted into the enclosure 42 by a known leg member or beam (not shown). The member is fixedly supported in a floating state.

  Further, a predetermined space 41 is provided around the heat and waterproof means 40, and a surrounding body 42 having one end made of, for example, a steel material having rigidity is surrounded. In addition, a lid 43 is fastened and held in a hermetically sealed state by a known fastening means (not shown) at the flange portion provided at the open end of the surrounding body 42.

  Further, as shown in FIG. 1, the hermetic plug 36 is provided with a hole penetrating vertically in the longitudinal direction, that is, the axial direction, and the first gas supply pipe 44 is disposed in a sealed state in this hole. Has been. The first gas supply pipe 44 is preferably formed of a material that is physically and chemically stable and has a high chemical resistance, such as quartz and ceramics, like the container 35. However, the present invention is not limited to this. One end of the first gas supply pipe 44 passes through the sealing plug 36 in the axial direction and opens to the inside of the container 35. The other end of the first gas supply pipe 44 extends from the sealing plug 36 through the lid 43 to the outside, and is connected to one end of the accumulator 45.

  A second gas supply pipe 46 is further connected to the one end of the accumulator 45. In order to increase the internal pressure of the container from the second gas supply pipe 46 until the interior of the container 35 reaches, for example, 50 MPaG, gas is sent in stages from the gas supply source 47. As the gas used here, nitrogen gas, neon gas, and argon gas having chemically stable characteristics that do not cause a specific chemical reaction to a workpiece (not shown) accommodated in the container 35. Noble gases such as are desirable. However, it is naturally possible to use oxygen gas or, in some cases, air, when verifying the oxidation characteristics or the like of a metal. However, in the illustrated example, it is assumed that nitrogen gas is used as an example. As shown in the figure, the first gas supply pipe 44 includes a known on-off valve 48, a check valve 49, and a pressure gauge 50. The second gas supply pipe 46 also includes an on-off valve 51, a reverse valve. A stop valve 52, a pressure gauge 53, and the like are attached. The first gas supply pipe 44 is further connected to a release pipe 55 equipped with an on-off valve 54. Here, the on-off valve 51 is in a second gas supply pipe 46 connecting the gas supply source 47 and the accumulator 45 and supplies the gas flowing out from the accumulator 45 to the container 35 side. It is arranged at a position to block the 47 side.

  Furthermore, as shown in the figure, one end of the first water supply pipe 56 communicates with the space 41 formed inside the enclosure 42. A second water supply pipe 61 is connected to the other end of the pipe 56. The second water supply pipe 61 supplies water to the internal space of the enclosure 42 under pressure, and a water supply pump 57 for supplying pressure to fill the internal space 41 with water except for the portion surrounded by the waterproof means 40. Is connected. The first water supply pipe 56 is similarly equipped with a known on-off valve 58, check valve 59, and pressure gauge 60. Further, a branch pipe 67 connected from the portion where the first water supply pipe 56 and the second water supply pipe 61 are connected to the other end opposite to the one end of the accumulator 45 is provided. It is provided. For this reason, the accumulator 45 receives the pressure of the gas supply source 47 and the pressure of the water supply pump 57 at both ends facing each other. Further, the second water supply pipe 61 is also equipped with a known on-off valve 62, check valve 63, and pressure gauge 64. The first water supply pipe 56 is provided with a release pipe 66 to which an on-off valve 65 is attached. Here, the on-off valve 62 is in a second water supply pipe 61 that connects the water supply pump 57 and the accumulator 45, and supplies water that flows out of the accumulator 45 to the enclosure 42 side, but on the side of the water supply pump 57. It is arranged in the position to prevent.

  That is, the device according to the present invention includes an enclosure 42 having an open end, a lid 43 for sealing and sealing the open end of the enclosure 42, and an open end disposed inside the enclosure 42. A heat-resistant pressure vessel 35, a sealing plug 36 that hermetically seals the open end of the vessel 35, heating means 38 disposed around the vessel 35 in the enclosure 42, and the vessel 35 and heating in the enclosure 42 The heat-resistant cement 39 surrounding the means 38, the heat-resistant waterproof means 40 surrounding the container 35, the heat-resistant cement 39 and the heating means 38 in a liquid-tight state in the enclosure 42, and the processing gas into the container 35 A gas supply source 47 for supplying water, a water supply pump 57 for filling the inner space 41 of the enclosure 42 with water except for a portion surrounded by the waterproof means 40, a pressure of the gas supply source 47 and the water supply pump 57 pressure Accumulator 45 for receiving both ends of the gas, accumulator 45, second and first gas supply pipes 46, 44 connecting accumulator 45 and container 35, water supply pump 57 and accumulator. The accumulator 45 is in a second pipe connecting the gas supply source 47 and the accumulator 45, and the second and first water supply pipes 61 and 56 connecting the accumulator 45 and the internal space 41 of the enclosure 42. In the second pipe connecting the open / close valve 51, which is supplied to the position where the gas flowing out from the container 35 side is blocked but not to the gas supply source 47 side, the feed water pump 57 and the accumulator 45, The on-off valve 62 is arranged at a position where water supplied from the accumulator 45 is supplied to the enclosure 42 side but blocked to the water supply pump 57 side. , With each other to disclose high-temperature high-pressure generator comprising more.

  Hereinafter, a procedure for forming an extremely high temperature and high pressure atmosphere of, for example, about 1000 ° C. and 50 PMaG on the work housed in the container 35 in the present apparatus 10 will be described.

  First, the lid 43 is removed from the enclosure 42. Next, the sealing plug 36 is removed from the container 35, and one or more kinds of desired workpieces are placed inside the container 35. Next, a sealing plug 36 is applied to the opening of the container 35 to seal the container, and the enclosure 42 is completely sealed with the lid 43. This completes the initial preparation.

  Next, after confirming that both of the open / close valves 54 and 65 of the release pipes 55 and 66 are completely closed, the water supply pump 57 is operated. Normal pressure water supplied by the water supply pump 57 passes through the second water supply pipe 61, the open / close valve 62, the first water supply pipe 56, and the open / close valve 58, and is supplied to the space 41 inside the enclosure 42. Is done. After the space 41 is completely filled with normal pressure water, pressurized water is supplied to the inside via the pump 57. A part of the water supplied under pressure by the pump is supplied to the water supply side in the accumulator 45 through the branch pipe 67, and the pressure at the end of the accumulator 45 on the side of the water supply pump is increased. When the pump-side pressure in the accumulator 45 measured by the pressure gauges 64 and 60 reaches a predetermined value by the operation of the pump 57, the on-off valve 62 is closed.

  The predetermined value here refers to a maximum pressure value at which the heat-resistant pressure vessel 35 is not destroyed by pressure water, that is, a pressure close to the maximum pressure resistance value of the vessel 35, for example, a pressure of about 0.1 to 2 MPaG. Say. The pressure water supplied into the sealed enclosure 42 fills the surroundings of the container 35, the heater 38, the heat-resistant cement 39, and the heat-resistant waterproofing means 40. Since the heat-resistant cement 39 is completely surrounded by the heat-resistant waterproofing means 40, the pressure water is completely prevented from penetrating to the heat-resistant cement 39 and the heater 38. Further, since the container 35 is completely sealed by the sealing plug 36 and the O-ring 37, it is easily understood by those skilled in the art that this pressure water is prevented from entering the inside of the container 35. Like.

  After closing the on-off valve 62 of the second water supply pipe 61, supply of nitrogen gas is started from a gas supply source 47 such as a nitrogen gas cylinder. Nitrogen gas supplied from the nitrogen gas supply source 47 includes the second gas supply pipe 46, the open / close valve 51 in the open state, the nitrogen gas supply side in the accumulator 45, the first gas supply pipe 44, and the open / close valve in the open state. It is supplied to the inside of the container 35 through the first gas supply pipe 44 arranged along the longitudinal direction of the sealing plug 36 through 48. The high-pressure nitrogen gas supplied into the container 35 is such that the container 35 is sealed with the sealing plug 36, the internal pressure of the space 41 is in a high pressure state due to water pressure, and the sealing plug 36 is forcibly pressed into the container 35. Therefore, the high-pressure nitrogen gas is not released from the container. Further, after the pressure value of the nitrogen gas measured by the pressure gauges 53 and 50 becomes the same as the pressure of the feed water measured by the pressure gauges 64 and 60, nitrogen gas is further forcibly supplied. As a result, the pressure inside the container 35 further increases, and at the same time, the pressure at the nitrogen gas side end of the accumulator 45 increases.

  The supply of nitrogen gas is stopped before the sealing plug 36 that seals the container 35 reaches a pressure that causes the non-operating state, that is, the state in which the sealing plug 36 is opened, due to the nitrogen gas pressure inside the container. Close. This pressure can be easily recognized by monitoring the pressure gauges 53 and 50. This is because this pressure is approximately similar to the pressure (0.1 to 2 MPaG). At this time, the nitrogen gas side pressure of the accumulator 45 is in a state higher than the feed water pump side pressure. For this reason, the water contained in the water supply side end of the accumulator 45 and the water contained in the branch pipe 67 and the first water supply pipe 56 are forcibly supplied to the space 41 in the enclosure 42 by the differential pressure. The The check valves 49, 52, 59, 63 arranged in the first gas supply pipe 44, the second gas supply pipe 46, the first water supply pipe 56, and the second water supply pipe 61 are made of high pressure gas or high pressure water. It acts as a safety valve for preventing reverse flow.

  Next, the on-off valve 62 is opened, and the water supply pump 57 is operated again to start water supply to the internal space 41 of the enclosure 42. After the numerical values of the pressure gauges 64 and 60 attached to the water supply pipes 61 and 56 become equal to the numerical values of the pressure gauges 53 and 50 attached to the gas supply pipes 46 and 44, the water is further exceeded. Pump. As a result, the water supply side pressure of the accumulator 45 is again made higher than the nitrogen gas supply side pressure by the same degree as the above-mentioned pressure. For this reason, the gas contained in the gas side end of the accumulator 45 and the nitrogen gas in the first gas supply pipe 44 are pumped into the container 35. The on-off valve 62 in the second water supply pipe 61 is closed before the water supply side pressure in the accumulator 45 expands beyond the nitrogen gas supply side pressure to a predetermined differential pressure or more.

  Next, the on-off valve 51 in the second gas supply pipe 46 is opened, and gas pressure feeding is performed in the same manner as described above to increase the internal pressure of the container 35.

  Hereinafter, such an operation is sequentially repeated. In the present apparatus 34, since the pressure inside and outside the container 35 is increased little by little successively, there is no pressure difference between the inside and outside of the container 35 to the extent that the container is crushed. By repeating such an operation, a very high internal pressure can be safely generated in the container. According to the applicant's experiment, the internal pressure of the container 35 having a size of about 5 ml could be easily increased to an extremely high pressure of about 50 MPaG in only 5 minutes. As a procedure for starting the operation, in the above description, the supply of water is started first and then the gas is supplied. However, the present invention is not limited to this. It will be readily appreciated by those skilled in the art that water may be provided. In particular, in the case of the embodiments as shown in FIGS. 2 and 3 to be described later, since the escape of the sealing plug 36 is prevented even if the inside of the container 35 becomes a high pressure, it is not necessary to stick to the starting procedure.

  On the other hand, the internal temperature of the container 35 can be raised to about 1000 ° C., and if necessary, the temperature can be increased by adjusting the pressure, and the container temperature is first raised to about 1000 ° C. It is possible to increase the pressure after that and then increase the pressure. Furthermore, after the pressure is first raised to a predetermined value, heating can be started. Furthermore, the pressure and temperature can be increased intermittently, thereby expanding the research area of metallurgical and other new materials.

  When the pressure gas and pressure water in the container 35 and the space 41 are released after the desired experiment, work, etc. are completed, the pressure drop can be easily reduced by operating the on-off valves 54 and 65 of the release pipes 55 and 66. Can be achieved. The temperature lowering operation of the heating means 38 is achieved by cutting off the power supply of the means.

  The embodiment shown in FIG. 2 is a modification of the embodiment shown in FIG. 1, but most of them are similar to the embodiment shown in FIG. The same members as 1 are indicated by adding a to the same numbers. 2 differs from the embodiment of FIG. 1 in that the sealing plug 36a is pressed and held by the pressing member 70 in order to protect the sealing plug 36a from popping out when the internal pressure of the container 35a rises. That is. Here, the pressing member 70 extends through the hole provided in the lid body 43a to the outside of the lid body 43a, and an O-ring 71 is disposed between the lid body 43a and the pressing member 70. Ensuring sealing performance. Further, a nut member 72 having a screw hole at the center is fixed to the upper surface of the lid body 43a so that the pressing force of the pressing member 70 can be adjusted from the outside, and the screw member is pressed against the screw hole. The thread formed on the member 70 is screwed. For this reason, when the internal pressure of the container 35a rises, the pressing member 70 can be adjusted so that the sealing plug 36a does not pop out.

  Further, in the embodiment of FIG. 2, the first gas supply pipe 44a passes through the enclosure 42a and the container 35a and communicates with the lower portion of the O-ring 37a of the hermetic seal 36a. Thereby, the nitrogen gas supplied from the gas supply source 47a is supplied from the lower part of the O-ring 37a to the inside of the container 35a through the space between the sealing plug 36a and the inner surface of the container 35a. In FIG. 2, a release tube is provided as in FIG. 1, but those skilled in the art will understand that FIG. 2 is not shown for the sake of clarity.

  In the embodiment shown in FIG. 1, the members 38 and 39 surrounded by the heat and waterproof means 40 are fixed to the enclosure 42 by leg members or beam members not shown, but the embodiment shown in FIG. In the example, the heating means 38a and the heat-resistant cement 39a surrounded by the heat-resistant and waterproofing means 40a extend to the bottom of the surrounding body 42a and are directly fixed in a fixed state. Thereby, the quantity of the pressurized water supplied in the enclosure 42a can be reduced, and the pressurization condition achievement time in a container can be shortened. Furthermore, there is an advantage that it is easy to attach the conducting wire of the heating means 38a.

  The embodiment shown in FIG. 3 is a modification obtained by further improving the embodiment of FIG. Since most of this modification is similar to the embodiment shown in FIG. 2, the same members as those in the embodiment shown in FIG. To be described.

  The embodiment of FIG. 3 differs from the embodiment of FIG. 2 in that the heat-resistant cement 39b surrounding the heating means 38b arranged around the container 35b together with a part of the container fills the entire lower part of the enclosure 42b. The heat resistant waterproofing means 40b is arranged in a sealed state on the upper surface of the heat resistant cement 39b. Since the heat-resistant waterproofing means 40b is arranged in a sealed state on the upper surface of the heat-resistant cement 39b, the pressure water supplied into the enclosure 42b is supplied only to the upper part of the heat-resistant waterproofing means 40b. The amount of pressurized water supplied into the enclosure 42b can be further reduced as compared with the embodiment, thereby further shortening the time for achieving the pressurizing condition into the container 35b. In FIG. 3, a release tube is provided as in FIG. 1, but those not shown in FIG. 3 can be easily understood by those skilled in the art as in FIG.

  In the illustrated example, the ends of the first gas supply pipes 44, 44a, 44b and the ends of the second gas supply pipes 46, 46a, 46b are directly connected to one end of the accumulators 45, 45a, 45b. On the other hand, the first water supply pipes 56, 56a, 56b and the second water supply pipes 61, 61a, 61b are connected to the other ends of the accumulators 45, 45a, 45b via the branch pipes 67, 67a, 67b. In contrast, the first gas supply pipes 44, 44a, 44b and the second gas supply pipes 46, 46a, 46b are connected to the accumulators 45, 45a, 45b via branch pipes (not shown), The ends of the first water supply pipes 56, 56a, 56b and the second water supply pipes 61, 61a, 61b can be directly connected to the accumulators 45, 45a, 45b, respectively, and further the first gas supply pipe 4 44a, 44b, the second gas supply pipes 46, 46a, 46b, the first water supply pipes 56, 56a, 56b, and the second water supply pipes 61, 61a, 61b are all connected to the accumulators 45, 45a, 45b via the branch pipes. Obviously, it is also within the scope of the present invention.

  In the illustrated example, it is described that the water supply operation and the gas supply operation are performed manually, but this is for easy understanding of the operation procedure. In an actual machine, for example, a timer or a sequencer is used. It is possible to provide an automatic control device that automatically controls all the operations of these devices through other necessary equipment. Furthermore, in the above description, the volume of the used container is 5 ml, the upper limit of the internal temperature of the container is 1000 ° C., and the upper limit of the internal pressure is 50 MPaG. It has been found that an atmosphere of 1500 ° C. and 100 MPaG can be formed by the present apparatus using a cylindrical container having a height of 13 cm.

  The present invention is a heat-resistant pressure device, and can generate a high-temperature and high-pressure atmosphere equipped with a heat-resistant pressure vessel that can withstand an internal temperature of 1000 ° C. or higher and withstand an internal pressure of 50 MPaG or higher. A high-temperature and high-pressure generator is provided. For this reason, this device is particularly useful for the development and improvement of alloys, composite metals, and various new materials, including aluminum, copper, iron, and other various metal materials, and for various metal sintering operations. Can be usefully used. In addition, by melting a metal such as aluminum at a high temperature and adding ceramic particles to this, a composite product with enhanced ductility, toughness, rigidity, wear resistance, etc. of the metal is formed. Can be completely replaced by casting equipment.

  In the present invention, water that does not have compressibility that is not restricted by the regulations of the High Pressure Gas Safety Law is used as a pressure source. For example, a predetermined high temperature (for example, 1000 ° C.) and a predetermined level are used. Under high pressure conditions (for example, 50 MPaG), it is possible to easily and inexpensively form the metal, which makes it possible to easily and inexpensively place the desired metal under severe conditions that have not been possible before. It has become possible to easily and inexpensively carry out specific metallurgical experiments under such circumstances, and to elucidate the metallurgical properties of specific metals or the physicochemical properties of various alloys.
