When the microwave irradiation unit 3 irradiates microwaves, the inside can be sealed from the outside. The bottom of the chamber 36 may serve as a drain pan 15 .

[0043] The irradiation chamber 36 includes, for example, a heating chamber 36 for carrying the heating target 14 therein. and an exit door 410A for carrying out the heating target 14 from the irradiation chamber 36. 410B is provided.

[0044] The gas recovery section 107 includes a gas recovery pipe 20 connected to the irradiation chamber 36 and a gas recovery pipe 22 connected to the irradiation chamber 36. A suction pump 24 that sucks the gas in the chamber 36 into the gas recovery pipe 20, and a liquefaction device 25 for liquefying the heated object 1. The gas released from the gas recovery pipe 20 is returned to the irradiation chamber 4 by a suction pump 24. The gas is collected from the tank 36 and sent to the liquefaction device 25. The liquefaction device 25, for example, Cooling the body liquefies the gas.

[0045] The heating target 14 may contain a metal element or a metal compound such as an alloy. Examples of metals are iron (Fe), nickel (Ni), copper (Cu), gold (Au), and silver. (Ag), aluminum (Al), cobalt (Co), tungsten (W), titanium (T i), chromium (Cr), molybdenum (Mo), beryllium (Be), magnesium (Mg ), tin (Sn), cerium (Ce), lead (Pb), mercury (Hg), sodium (Na) , bismuth (Bi), and gallium (Ga).

The sintering temperature of cobalt (Co) is, for example, 1100°C. The melting point of cobalt (Co) is 1455°C.

[0047] The heating target 14 may contain one type of metal or multiple types of metals. Examples of metal compounds include alloys made of multiple metal elements, and compounds made of metal and nonmetal elements. Alloys, metal oxides, metal hydroxides, metal chlorides, metal carbides, metal borides, The metal raw material may include, but is not limited to, a metal oxide and a metal sulfide as an alloy component. For example, silicon (Si), manganese (Mn), chromium (Cr), nickel (Ni), Carbon (C), Boron (B), Copper (Cu), Aluminum (Al), Titanium (Ti), Ni Nb, vanadium (V), zinc (Zn), antimony (Sb), palladium (Pd ), lanthanum (La), gold (Au), potassium (K), cadmium (Cd), indium (In), molybdenum (Mo), sulfur (S), etc.

[0048] The shape and size of the heating target 14 are not particularly limited. The heating target 14 may be a plate or a sheet. The heating target 14 may include a compact of metal powder. The object to be heated 14 may include metal pieces. The object to be heated 14 may be a briquette.

[0049] When the heating object 14 is a compact of a metal material, when the metal raw material is formed into the compact, For example, the metal raw material is subjected to a pressure of 1 MPa or more, 100 MPa or more, or 200 MPa or more. , 2000MPa or less, 1900MPa or less, or 1800MPa or less pressure is applied. By applying pressure, the heating object 14 is heated and the metal is sintered or melted and solidified. The metal solids produced by this method tend to be dense. These include cold isostatic pressing (CIP), hot isostatic pressing (HIP), and roller pressing. can be.

[0050] The holding member 425 is a heat promoting agent that promotes heating of the heating target 14 irradiated with microwaves. may also include:

[0051] The heating accelerator is at least above the temperature range at which the metal material of the heating target 14 absorbs microwaves. A part of the material may contain an absorbing material that absorbs microwaves in a low temperature range. The melting point of the absorbing material is higher than that of the metallic raw material. Some of the temperatures are lower than the temperature range at which metal raw materials absorb microwaves. The temperature range is, for example, 300°C or more and 1200°C or less, 450°C or more and 1100°C or less, or The temperature range in which the absorbing material absorbs microwaves is, for example, between 600°C and 800°C. For example, 25℃ to 1000℃, 50℃ to 1000℃, 75℃ to 1000℃ 100℃ to 1000℃, 250℃ to 900℃, or 400℃ to 6 It is below 00℃.

[0052] At least a part of the temperature range in which the absorbing material absorbs microwaves is the temperature range in which the metal raw material absorbs microwaves. It is preferable that the temperature range overlaps with the temperature range where the metal raw material absorbs microwaves. Since microwaves are absorbed in a temperature range at least partially lower than the temperature range in which they are generated, Therefore, the absorbing material must reach the temperature range where the metal raw material absorbs microwaves. It is possible to heat the metal raw material up to this point.

[0053] Therefore, if the heating promoter contains an absorbing material, the temperature of the metal raw material will absorb microwaves. The temperature range is reached more quickly, and the heating time of the metal raw material can be shortened. The absorbing material is at least partially in a temperature range lower than the temperature range in which the metal raw material absorbs microwaves. It absorbs microwaves, so it is possible to prevent the heating accelerator from being heated more than necessary. Therefore, even while the metal raw material is being sintered or melted by microwave irradiation, The heat enhancer, which includes an absorbent material, can be shape stable.

[0054] Absorbent materials include, for example, carbon materials. Examples of carbon materials include carbon black, non- Examples include, but are not limited to, amorphous carbon, graphite, silicon carbide, carbon resins, and metal carbides. The absorbing material must be heated at a temperature lower than the temperature range in which the metal material to be heated absorbs microwaves. Metallic raw materials, metallic nitrides, metallic oxides, and metals, some of which absorb microwaves in the low temperature range. The absorbent material may be a compound of these. It is preferable that the absorbent material does not contain volatile components. It is possible to prevent the microwaves from being absorbed by the volatile components.

[0055] The heating accelerator has higher microwave transmittance than the metal raw material and absorbs microwaves less than the metal raw material. The insulating material may contain a low melting point of the metal raw material. The insulating material has a low microwave absorption rate, which makes it difficult for microwaves to be irradiated. Even when irradiated with heat, the heat generated is low, and the insulating effect is excellent. Because the point is high, the shape remains stable even when irradiated with microwaves. While the injected metal raw material is sintering or melting, the heat promoter containing the insulating material remains in its shape. It can be stable.

[0056] The insulating material may include a metal oxide or a metalloid oxide. Examples of metal and semimetal oxides include aluminum oxide (Al2O3), silicon oxide ( SiO2), magnesium oxide (MgO), zirconium oxide (ZrO2), and titanium oxide Examples of the oxide include, but are not limited to, aluminum oxide (AlO 3) has a melting point of 2072°C. The melting point of silicon dioxide (SiO2) is 1710°C. The melting point of magnesium (MgO) is 2852°C. That's fine.

[0057] The heating promoter may include a reducing material that reduces the metal source. Examples of reducing materials include carbon and silicon carbide. The carbon material used as the absorbing material may also function as the reducing material.

[0058] The heat promoter may consist of only insulating material or only absorbing material. It may consist of only reducing material or may contain a mixture of insulating and absorbing materials. It may contain a mixture of absorbent and reducing materials, or a mixture of reducing and insulating materials. It may contain a mixture of insulating material, absorbing material and reducing material. In addition, the properties and functions of the heat insulating material, the absorption material, and the reduction material may overlap. For example, carbon materials can function both as absorbents and as reducing materials. possible.

[0059] As shown in FIG. 3, when the heating object 14 is irradiated with microwaves, the heating object 14 The contact member 420 containing the accelerator may be brought into contact with the object to be heated. The contact member 420 may be movable in the direction of gravity. The material 420 may contain a heat promoting agent. The object to be heated 14 is held by a holding member 425 containing a heat promoting agent. By sandwiching the object to be heated 14 between contact members 420 containing a heating promoter, heating of the object to be heated 14 is promoted.

[0060] In order to heat the heating object 14 uniformly, the heating object 14 is rotated relative to the microwave irradiation unit 3. For example, the heating device according to the embodiment may be configured to rotate a heating element disposed on the holding member 425. The apparatus further includes a rotating table 440 for rotating the heat target 14. The rotating table 440 is connected to the shaft 430. The rotating table 440 rotates around the axis 430. The longitudinal direction of the axis 430 is, for example, The microwave irradiation unit 3 is parallel to the irradiation window of the microwave irradiation unit 3. perpendicular to the main direction of wave travel.

[0061] When the heating target 14 is rotated on the turntable 440, the contacts in contact with the upper surface of the heating target 14 are The contact member 420 may be rotated. The contact member 420 is passively moved in accordance with the rotation of the heating target 14. The contact member 420 may be connected to a shaft 435. An opening may be provided at the center of the irradiation chamber 36, and the shaft 435 may be inserted into the opening. A sleeve 431 into which the shaft 435 is inserted may be provided. The longitudinal direction of 31 is parallel to the axis 430, and the center of the axis 430 and the center of the axis 435 are on the same line. The contact member 420 rotates about an axis 435.

[0062] When the heating target 14 contains a metal oxide, the heating target 14 is irradiated with microwaves. When the heating object 14 contains a metal, the heating object 14 is heated to a sintering temperature. As described above, when the material is heated to a temperature close to the melting point, a dense sintered body is easily obtained. The heating object 14 is heated to 1400°C or higher or 1500°C or higher by microwaves. When the heating target 14 is melted and solidified, the heating target 14 is heated to a temperature equal to or higher than the melting point. Just do that.

[0063] When the heating target 14 is heated, the components contained in the heating target 14 are liquefied and vaporized. Liquid and gas may be generated from the object 14. The liquid and gas generated from the heated object 14 are irradiated. If the particles remain in the irradiation chamber 36, they will adhere to the heating target 14 and the inner wall of the irradiation chamber 36. When the microwave irradiation is completed and the temperature in the irradiation chamber 36 drops, Liquids and gases adhering to the heat target 14 and the interior walls of the irradiation chamber 36 may solidify.

[0064] The liquid and gas generated from the heated object 14 may be impurities. It is undesirable that the liquid and gas generated from the heating element 4 adhere to the heating object 14 again. The liquid and gas generated from the heating object 14 are applied to the microwave transmission window of the microwave irradiation unit 3. If the microwave irradiation chamber 36 is heated, the microwave irradiation efficiency will be reduced, which is undesirable. When a measuring device such as a thermometer is provided, the liquid generated from the heating object 14 is Adherence of gas is undesirable because it can reduce the measurement accuracy of the measuring instrument.

[0065] Furthermore, if the heating target 14 before heating contains oil, when the oil is heated, benzene and Toxic gases such as toluene may be produced.

[0066] However, the heating device according to the embodiment can effectively prevent the microwaves from being emitted from the object to be heated 14. Since the recovery unit is configured to recover the fluid generated from the object to be heated 14, The gas is introduced into the heating target 14, the inner wall of the irradiation chamber 36, the microwave-transparent window, and the measuring equipment. It is possible to prevent the toxic gas from diffusing around the heating device. It is possible to suppress this.

[0067] The heating device according to the embodiment includes a pre-heating chamber 400 connected to the irradiation chamber 36. The pre-heating chamber 400 may further include a heating chamber for heating the material before it is irradiated with microwaves. The heating target 14 is placed in the pre-heating chamber 400. The pre-heating chamber 400 and the irradiation chamber 36 are provided with a loading door (not shown) for the purpose of A loading door 410A is arranged between the heating chamber 400 and the irradiation chamber 36. When the object 14 is to be moved, the entrance door 410A is opened.

[0068] The pre-heating chamber 400 can function as a load lock chamber. For example, the heating device The gas environment in the irradiation chamber 36 and the gas environment in the pre-heating chamber 400 are made the same. For example, the irradiation chamber 36 may include a gas introduction pipe 255 and A gas exhaust pipe 260 is provided, and a gas inlet pipe 256 and a gas exhaust pipe 260 are connected to the pre-heating chamber 400. 61 will be established.

[0069] With the irradiation chamber 36 sealed, the gas in the irradiation chamber 36 is discharged from the gas exhaust pipe 260. The gas is discharged, and a gas of a desired composition is introduced into the irradiation chamber 36 through the gas introduction pipe 255. By doing so, it is possible to set desired gas conditions in the irradiation chamber 36. In addition, with the pre-heating chamber 400 sealed, the gas is discharged from the gas exhaust pipe 261 to the pre-heating chamber 400. The gas in the pre-heating chamber 400 is discharged, and a gas of a desired composition is introduced into the pre-heating chamber 400 through the gas inlet pipe 256. By introducing the gas into the pre-heating chamber 400, the gas in the pre-heating chamber 400 can be set to a desired condition. It is Noh.

[0070] The gas introduced into the pre-heating chamber 400 and the irradiation chamber 36 was an inert gas. Examples of inert gases include argon (Ar) and helium (He). The gas introduced into the pre-heating chamber 400 and the irradiation chamber 36 is a neutral gas. Examples of neutral gases include nitrogen (N2), dry hydrogen (H2), and ammonia ( The gases introduced into the pre-heating chamber 400 and the irradiation chamber 36 include The reducing gas may be a reducing gas. Examples of reducing gases include hydrogen (H2), carbon monoxide (CO ), and hydrocarbon gases (CH4, C3H8, C4H 10 etc.)

[0071] After the heating target 14 is placed in the pre-heating chamber 400, the pre-heating chamber 400 is sealed. The gas conditions in the pre-heating chamber 400 are made the same as the gas conditions in the irradiation chamber 36 . Thereafter, the entrance door 410A between the pre-heating chamber 400 and the irradiation chamber 36 is opened. The heat target 14 is moved into the irradiation chamber 36, and the entrance door 410A is closed, whereby the irradiation It is possible to prevent outside air from entering the injection chamber 36.

[0072] The bottom surface of the pre-heating chamber 400 and the bottom surface of the irradiation chamber 36 form a continuous stage 1. The heating device according to the embodiment may irradiate the heating target 14 from within the pre-heating chamber 400. The heating element may further include a transport device for moving the heating element into the irradiating chamber 36. The apparatus is configured to push the object 14 from within the pre-heating chamber 400 toward the irradiation chamber 36. The pushing part 11 may include, for example, a rod, and may be used to push the chamber before heating. The irradiation chamber 36 is reciprocated between the rotor 400 and the irradiation chamber 36 .

[0073] The heating device according to the embodiment includes a post-heating chamber 401 connected to the irradiation chamber 36. The post-heating chamber 401 may further include a heating element after being irradiated with microwaves. The image 14a is placed in the irradiation chamber 36. A carry-out door 410 is provided between the irradiation chamber 36 and the post-heating chamber 401. B is placed, and the heating target 14a is moved from the irradiation chamber 36 to the post-heating chamber 401. When the heating chamber 401 is opened, the carrying-out door 410B is opened. An exit door 411 is provided for carrying out the heat target 14a.

[0074] The post-heating chamber 401 can function as a load lock chamber. For example, the heating device The gas environment in the irradiation chamber 36 and the gas environment in the post-heating chamber 401 are made the same. For example, a gas introduction pipe 257 may be connected to the post-heating chamber 401. After heating, the chamber 401 is sealed, and the gas exhaust pipe 262 is provided. After heating, the gas in the chamber 401 is discharged from the gas inlet pipe 262, and a gas of the desired composition is introduced from the gas inlet pipe 257. By introducing the gas into the post-heating chamber 401, the gas in the post-heating chamber 401 It is possible to set the desired conditions.

[0075] Before the heating target 14a is transferred from the irradiation chamber 36 to the post-heating chamber 401, The post-heating chamber 401 is sealed, and the gas conditions in the post-heating chamber 401 are the same as those in the irradiation chamber 36. After that, the gas conditions are set to the same as those in the irradiation chamber 36 and the post-heating chamber 401. The exit door 410B is opened, the heating target 14a is moved into the post-heating chamber 401, and the carry-out door 4 10B is closed, and then the carrying-out door 411 of the post-heating chamber 401 is opened. When the heating target 14a is carried out from the irradiation chamber 36, outside air is prevented from entering the irradiation chamber 36. It is possible to prevent this.

[0076] The heating device according to the embodiment moves the heating target 14a from the inside of the chamber 401 to the outside after heating. The conveying device may further include a conveying device for conveying the heating target 14a to a chamber after heating. It may also include a caterpillar conveyor 19 configured to transport the goods from inside the bar 401 to the outside. good.

[0077] In the heating apparatus according to the embodiment shown in FIG. 4, the irradiation chamber 36 has a loading port 412 and The heating device shown in FIG. The heating target 14 is transported through the irradiation chamber 36 via a transport device. For example, a roller conveyor 31 on which the heating object 14 flows and a heating element 14 on the roller conveyor 31 The conveyor includes a pushing unit 11 that pushes the object 14. A plurality of objects 14 to be heated flow on the roller conveyor 31. Each of the plurality of heating targets 14 is successively irradiated with microwaves in the irradiation chamber 36. That's fine.

[0078] The microwave irradiation unit 3 may be installed at any position in the irradiation chamber 36. In this example, the position of the target 14 to be heated in the irradiation chamber 36 is lower in the direction of gravity than the position where the target 14 to be heated is placed.
