Description

Technical Field

[0001] This utility model relates to the field of alloy smelting, and more specifically to a vacuum induction melting device for preparing magnesium-nickel alloys. Background Technology

[0002] The heating principle of a vacuum induction melting furnace is based on electromagnetic induction heating. It utilizes the heat generated by the flow of high-frequency current within the metal to melt it. It is a device for melting metals in a vacuum environment and is widely used in the preparation of high-purity, high-performance metals and alloys. This type of furnace is particularly suitable for melting reactive metals, high-melting-point metals, and alloys requiring strict control of composition and impurity content, such as magnesium-nickel alloys.

[0003] Magnesium-nickel alloys are widely used in solid-state hydrogen storage, aerospace, and the automotive industry. Magnesium has a melting point of 650℃ and a boiling point of 1170℃, with a relatively low density; while nickel has a melting point of 1455℃ and a boiling point of 2730℃. In the traditional magnesium-nickel alloy smelting process, the mixture of magnesium and nickel melts upon heating. Due to the high melting point of nickel, the magnesium begins to evaporate into magnesium vapor before the nickel is completely molten. This severely affects the metal content of the magnesium-nickel alloy, thus compromising its quality.

[0004] Therefore, how to provide a vacuum induction melting apparatus for preparing magnesium-nickel alloys that can overcome the above-mentioned problems is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the present invention provides a vacuum induction melting apparatus for preparing magnesium-nickel alloys.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A vacuum induction melting apparatus for preparing magnesium-nickel alloys, comprising:

[0008] Chassis;

[0009] A smelting assembly includes a crucible one, a crucible two, an induction coil, and a rotating component one. Crucible one and crucible two are both arranged inside a housing. An induction coil is mounted on the outer wall of crucible one and the outer wall of crucible two, respectively. The two induction coils are connected to an external power source. Two rotating components one are provided and mounted on the housing. The rotation output ends of the two rotating components one are fixed to crucible one and crucible two, respectively. The height directions of crucible one and crucible two are perpendicular to the rotation axis of the rotation output ends of the rotating components one. The rotation axis of the rotation output ends of the rotating components one is horizontally arranged. Crucible one can hold pure magnesium, and crucible two can hold pure nickel.

[0010] A stirring assembly includes a crucible three and a rotating component two. The crucible three is arranged vertically and can communicate with the interior of the casing. Molten magnesium in the crucible one and molten nickel in the crucible two can flow downward into the crucible three. The rotating component two is mounted on the casing. The rotation output end of the rotating component two is fixed to the crucible three. The axis of the rotation output end of the rotating component two is arranged vertically.

[0011] A gas replacement assembly includes a vacuum pump and a gas storage cylinder containing an inert gas. The pumping end of the vacuum pump and the outlet end of the gas storage cylinder are both connected to the interior of the chassis.

[0012] As can be seen from the above technical solution, compared with the prior art, this utility model discloses a vacuum induction melting device for preparing magnesium-nickel alloy. This utility model sets crucible one and crucible two in the machine box. Crucible one can hold pure magnesium and crucible two can hold pure nickel. Induction coils are respectively set on the outside of crucible one and crucible two. After the induction coils are energized, they can heat and melt the magnesium inside crucible one and the nickel inside crucible two. Magnesium and nickel can be heated and melted quickly. The energizing current of the two induction coils is different, which ensures that magnesium and nickel can be completely melted, and also ensures that magnesium will not overheat and form a large amount of vapor. The ratio of magnesium or nickel in the magnesium-nickel alloy meets the quality requirements of magnesium-nickel alloy. By designing rotating component one and crucible three, each of the two rotating components one can drive crucible one or crucible two to rotate. Through the flipping of crucible one and crucible two, molten magnesium and molten nickel can flow downwards into crucible three, where magnesium and nickel can quickly mix and form a magnesium-nickel alloy. By designing rotating component two, during the process of adding magnesium and nickel into crucible three, rotating component two can drive crucible three to rotate at a certain speed, where magnesium and nickel can quickly mix. The rotating crucible three can improve the uniformity of magnesium and nickel mixing. By designing a gas replacement component, air in box one and box two can be extracted, and inert gas can be filled into box one and box two, ensuring that magnesium and nickel are not oxidized during heating.

[0013] Preferably, the chassis includes a first housing, a cover plate, support legs, and a second housing. The first housing has an opening at the top and is detachably sealed with the cover plate.

The support legs are arranged vertically and their upper ends are fixed to the first housing. The second housing is located below the first housing, and its upper end is sealed and fixed to the lower end of the first housing. A connecting pipe is vertically and tightly inserted into the lower end of the first housing, and the lower end of the connecting pipe communicates with the second housing.

Each mounting bracket is fixed to crucible one and crucible two. Both handwheels are located outside the housing. The centerlines of the connecting shafts are horizontally arranged, parallel to each other, and together define a horizontal reference plane. The receiving cylinder is located below the horizontal reference plane and is centrally positioned between the two connecting shafts. The centerline along the length of crucible one, the centerline along the length of crucible two, and the centerline of the receiving cylinder together define a vertical reference plane. The operator can rotate the handwheel to flip crucible one or crucible two. Crucible one and crucible two can operate independently. When crucible one and crucible two are flipped, molten magnesium or molten nickel can flow smoothly into the receiving cylinder.

[0015] Preferably, the system also includes a chiller, and the side wall of the second housing has a cooling channel. The inlet and outlet of the chiller are respectively connected to the inlet and outlet of the cooling channel. The magnesium-nickel alloy inside the crucible can be rapidly cooled, making it easy for subsequent operators to remove it.

[0016] Preferably, the chassis further includes a base plate, which is horizontally arranged below the second housing body and vertically aligned with it. The third crucible is located above the base plate. The second rotating component is a geared motor, fixed to the lower surface of the base plate. The output shaft of the second rotating component passes through the surface of the base plate and is coaxially fixed with the third crucible. A telescopic cylinder is vertically fixed below the base plate, with its telescopic end fixed to the base plate. The lower end of the second housing body is open, and the base plate can seal the lower opening of the second housing body. The third crucible can be lowered, allowing the operator to remove the magnesium-nickel alloy inside.

[0017] Preferably, the system further includes a display, a first temperature sensor, a second temperature sensor, and a pressure sensor. The display is mounted above the cover plate.

Detailed Implementation

[0027] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] This utility model discloses a vacuum induction melting device for preparing magnesium-nickel alloy. The device consists of a crucible 6 and a crucible 7 inside the casing. The crucible 6 can hold pure magnesium, and the crucible 7 can hold pure nickel. Each of the crucibles 6 and 7 is fitted with an induction coil 8. When the induction coil 8 is energized, it can heat and melt the magnesium inside the crucible 6 and the nickel inside the crucible 7. The magnesium and nickel can be heated and melted quickly. The two induction coils 8 have different energizing currents, which ensures that the magnesium and nickel can be completely melted, while also preventing the magnesium from overheating and forming a large amount of vapor.

[0029] By designing rotating component one and crucible three 12, the two rotating components one can drive crucible one 6 or crucible two 7 to rotate respectively. Through the flipping of crucible one 6 and crucible two 7, molten magnesium and molten nickel can flow downward into crucible three 12 respectively. The magnesium and nickel in crucible three 12 can quickly mix and form a magnesium-nickel alloy.

[0030] Since magnesium and nickel are heated separately, the heating temperature of magnesium in crucible 6 is different from that of nickel in crucible 7, ensuring that magnesium does not form magnesium vapor and that the ratio of magnesium or nickel in the magnesium-nickel alloy meets the quality requirements of magnesium-nickel alloy.

[0031] The rotating part includes a handwheel 10. The two handwheels 10 can be operated independently. There are three ways to add molten magnesium and molten nickel to the crucible 3 12: first, pour in molten magnesium and then pour in molten nickel; second, pour in molten nickel and then pour in molten magnesium; and third, pour in molten magnesium and molten nickel at the same time.

[0032] By designing the rotating component 2 13, during the process of adding magnesium and nickel into the crucible 3 12, the rotating component 2 13 can drive the crucible 3 12 to rotate at a certain speed, so that the magnesium and nickel in the crucible 3 12 can be mixed quickly. The rotating crucible 3 12 can improve the mixing uniformity of magnesium and nickel. Of course, even if the crucible 3 12 does not rotate, the molten magnesium and nickel can still be mixed, but the mixing time is slightly longer.

[0033] By designing a chiller 18, the magnesium-nickel alloy formed by mixing in crucible 3 12 can be cooled quickly, making it easy for users to remove it.

[0034] By designing the base plate 5 and the telescopic cylinder 19, the crucible 3 12 can be moved downwards, which makes it easy for users to remove the solidified magnesium-nickel alloy from the crucible 3 12.

[0035] By designing a display 20, a temperature sensor 1 21, a temperature sensor 22, and a pressure sensor 23, on the one hand, the temperature inside crucible 1 6 and crucible 2 7 can be known in real time when magnesium and nickel are heated; on the other hand, when gas is replaced inside box 1 and box 2 4, the pressure inside box 1 and box 2 4 can be known by using pressure sensor 23.

[0036] By designing a gas replacement component, the air inside chamber 1 and chamber 2 4 can be extracted, and inert gas can be filled into chamber 1 and chamber 2 4 to ensure that magnesium and nickel are not oxidized when heated.

[0037] By designing the connecting pipe 16 and the receiving cylinder 17, when crucible one 6 and crucible two 7 are flipped, the molten magnesium and molten nickel flowing downwards can be reliably received by the receiving cylinder 17, and the molten magnesium or molten nickel in the receiving cylinder 17 can flow smoothly into crucible three 12.

[0038] Example

[0039] See appendix Figure 1-6 This is a schematic diagram of the overall and partial structure of one embodiment of the present invention. Specifically, the present invention discloses a vacuum induction melting apparatus for preparing magnesium-nickel alloys, comprising:

[0040] Chassis;

[0041] The melting assembly includes a crucible 1 (6), a crucible 2 (7), an induction coil 8, and a rotating component 1. Crucibles 1 (6) and 2 (7) are identical in shape, size, and material. Crucible 1 (6) is cylindrical. Both crucibles 1 (6) and 2 (7) are housed within a casing. An induction coil 8 is mounted on the outer wall of both crucibles 1 (6) and 2 (7). The two induction coils 8 are connected to an external power source, which supplies alternating current to them. Two rotating components 1 are mounted on the casing. The rotation of the two rotating components 1... The output ends are fixed to crucible 6 and crucible 7 respectively. The height direction of crucible 6 and crucible 7 are both perpendicular to the rotation axis of the rotation output end of the rotating component 1. The rotation axis of the rotation output end of the rotating component 1 is arranged horizontally. Crucible 6 can hold pure magnesium, and crucible 7 can hold pure nickel. When the induction coil 8 is energized, the pure magnesium in crucible 6 and the pure nickel in crucible 7 will melt due to heat. The rotation of the rotating component 1 can tilt and flip crucible 6 and crucible 7, and the molten pure magnesium or pure nickel can be poured out.

[0042] The stirring assembly includes a crucible 12 and a rotating component 13. The crucible 12 is vertically arranged and can communicate with the inside of the machine housing. The crucible 12 is cylindrical. Molten magnesium in crucible 6 and molten nickel in crucible 7 can flow downward into crucible 12. The rotating component 13 is mounted on the machine housing. The rotation output end of the rotating component 13 is fixed to the crucible 12. The axis of the rotation output end of the rotating component 13 is arranged vertically. During the process of molten magnesium and molten nickel flowing into crucible 12, the rotating component 13 drives crucible 12 to rotate at a certain speed, thereby achieving a certain degree of mixing of molten magnesium and molten nickel.

[0043] The gas replacement assembly includes a vacuum pump 14 and a gas storage cylinder 15. The gas storage cylinder 15 contains inert gas. Both the suction end of the vacuum pump 14 and the outlet end of the gas storage cylinder 15 are connected to the inside of the chassis. To prevent magnesium or nickel from being oxidized when heated and melted, the gas inside the chassis needs to be replaced. Before heating magnesium and nickel, the vacuum pump 14 is started to evacuate the chassis. After the pressure inside the chassis reaches a certain level, the inert gas in the gas storage cylinder 15 is released into the chassis, thereby isolating magnesium or nickel from the outside air when heated and melted. A valve (not shown in the figure) is connected in series between the suction end of the vacuum pump 14 and the chassis, and a valve (not shown in the figure) is connected in series between the gas storage cylinder 15 and the chassis.

[0044] The chassis includes a housing 1, a cover plate 2, support legs 3 and a housing 2 4. The rectangular housing 1 has an opening at the top and is detachably sealed with a rectangular cover plate 2. Crucible 1 6 and crucible 2 7 are both located inside the housing 1. Rotating component 1 is installed on the housing 1.

[0045] The support legs 3 are arranged vertically and their upper ends are fixed to the box body 1. There are four support legs 3, each arranged at one of the four corners of the box body 1.

[0046] A cylindrical box 2, 4, is located below box 1. Box 2, 4 is situated within the area enclosed by four supporting legs 3. The upper end of box 2, 4, is sealed and fixed to the lower end of box 1. A connecting pipe 16 is vertically and tightly inserted and fixed into the lower end of box 1. The connecting pipe 16 is coaxially arranged with box 2, 4, and its lower end is connected to box 2. The upper end of the connecting pipe 16 is integrally formed with a receiving cylinder 17 that communicates with its interior. The receiving cylinder 17 is located inside box 1, vertically arranged, and has an opening at its top. (The text abruptly ends here, likely due to an incomplete sentence or missing information.) When crucible 1 (6) or crucible 2 (7) is rotated, the molten magnesium in crucible 1 (6) and the molten nickel in crucible 2 (7) can flow downward into the receiving cylinder 17; crucible 3 (12) can be located inside box 2 (4), and the lower end of the connecting pipe 16 is directly opposite and connected to the vertical position of crucible 3 (12), so that the molten magnesium or molten nickel can pass through the receiving cylinder 17 and the connecting pipe 16 in sequence and finally flow into crucible 3 (12); rotating part 2 (13) is installed below box 2 (4); the suction end of vacuum pump 14 and the outlet end of gas storage bottle 15 are both connected to the inside of box 1 (1) and box 2 (4).

[0047] More specifically, each rotating component includes a connecting shaft 9, a handwheel 10, and a mounting bracket 11. Both connecting shafts 9 are rotatably mounted on the housing 1. Each handwheel 10 is coaxially fixed to one end of each connecting shaft 9, and the other end of each connecting shaft 9 is fixed to one mounting bracket 11. Each mounting bracket 11 is fixed to crucible 6 and crucible 7. Both handwheels 10 are located outside the housing 1. The axis of the connecting shafts 9 is horizontally arranged, and the axis of the two connecting shafts 9 is parallel to each other and can jointly define a horizontal reference plane. The receiving cylinder 17 is located below the horizontal reference plane and is centrally arranged between the two connecting shafts 9. The centerline of crucible 6 in the length direction and the centerline of crucible 7 in the length direction are... The center line and the center line of the receiving cylinder 17 together define a vertical reference plane; rotating the handwheel 10 can deflect either crucible 6 or crucible 7. There is a certain rotational friction between the connecting shaft 9 and the box 1, or in other words, the connecting shaft 9 has a certain damping when it rotates. When the handwheel 10 is not rotated, crucible 6 or crucible 7 can stop rotating and crucible 6 and crucible 7 will not rotate on their own; furthermore, the center of gravity of crucible 6 containing magnesium and crucible 7 containing nickel are both located below the axis of the connecting shaft 9. Therefore, when the handwheel 10 is not rotated, the open end of crucible 6 and the open end of crucible 7 will not flip down to face downwards, that is, the magnesium in crucible 6 and the nickel in crucible 7 will not spill out at will.

[0048] More specifically, it also includes a chiller 18. The side wall of the second chamber 4 has a cooling channel. The inlet and outlet of the chiller 18 are connected to the inlet and outlet of the cooling channel, respectively. The chiller 18 can deliver cold water to the inside of the side wall of the second chamber 4, thereby cooling the second chamber 4 and the crucible inside it. After the molten magnesium and molten nickel enter the third crucible 12 and are mixed as the third crucible 12 rotates, the magnesium-nickel alloy in the third crucible 12 can be cooled relatively quickly.

[0049] More specifically, the chassis also includes a circular base plate 5, which is horizontally arranged below the second chassis 4 and the two are vertically opposite each other. The third crucible 12 is located above the base plate 5. The second rotating component 13 is a geared motor, which is fixed to the lower plate surface of the base plate 5. The output shaft of the second rotating component 13 passes through the plate surface of the base plate 5 and is coaxially fixed with the third crucible 12. The third crucible 12 can rotate around its own axis.

[0050] The bottom of the second box 4 is open, and the bottom plate 5 can block the bottom opening of the second box 4;

[0051] A telescopic cylinder 19 is vertically fixed below the base plate 5. The telescopic end of the telescopic cylinder 19 is fixed to the base plate 5. During the heating, melting and mixing stages of magnesium and nickel, the telescopic end of the telescopic cylinder 19 is in the extended state, that is, the base plate 5 seals the lower opening of the box 4. When the magnesium-nickel alloy is prepared, the telescopic end of the telescopic cylinder 19 retracts, and the base plate 5 moves down, making it easier for the operator to take the magnesium-nickel alloy out of the crucible 12.

[0052] More specifically, it also includes a display 20, a temperature sensor 21, a temperature sensor 22, and a barometric pressure sensor 23.

[0053] The display 20 is mounted above the cover plate 2. Temperature sensor 21, temperature sensor 22, and pressure sensor 23 are all fixed on the cover plate 2. All three sensors are electrically connected to the display 20. The detection ends of temperature sensor 21, temperature sensor 22, and pressure sensor 23 are located inside the housing 1. Temperature sensor 21 and temperature sensor 22 are both infrared temperature sensors, meaning they are non-contact temperature sensors. The detection ends of temperature sensor 1 21 and temperature sensor 22 can be vertically aligned with crucible 1 6 and crucible 2 7 respectively. The detection ends of temperature sensor 1 21 and temperature sensor 22 can be aligned with the interior of crucible 1 6 and crucible 2 7 respectively. The above design ensures that the magnesium in crucible 1 6 and the nickel in crucible 2 7 can be monitored in real time. At the same time, crucible 1 6 and crucible 2 7 will not interfere with the detection ends of temperature sensor 1 21 and temperature sensor 22 when they are flipped.

[0054] During gas replacement, the pressure sensor 23 can monitor the pressure inside the chamber 1 and chamber 2 in real time. The pressure data of the pressure sensor 23, the temperature data of the temperature sensor 1 and the temperature data of the temperature sensor 22 are all displayed on the display 20 in real time.

[0055] When using this device

[0056] First, open the cover plate 2 and add the pure magnesium ingot and pure nickel ingot to be melted into crucible 6 and crucible 7 respectively. Then, put the cover plate 2 back on and the telescopic cylinder 19 moves the bottom plate 5 upward so that the bottom plate 5 blocks the lower opening of the box 4.

[0057] The second step is to open valve 1 and start vacuum pump 14. Observe the air pressure data of air pressure sensor 23 through display 20. When the air pressure inside chamber 1 and chamber 2 4 drops to a certain value, close vacuum pump 14 and valve 1 to ensure that chamber 1 and chamber 2 4 have a certain degree of vacuum. Then open valve 2 and inert gas in gas storage bottle 15 is filled into chamber 1 and chamber 2 4. When the air pressure inside chamber 1 and chamber 2 4 reaches a certain value, close valve 2.

[0058] Third step: In the initial state, crucible 6 and crucible 7 are both arranged vertically. At this time, the two induction coils 8 are energized. Temperature sensor 1 can monitor the temperature of magnesium in crucible 6 in real time, and temperature sensor 2 can monitor the temperature of nickel in crucible 7 in real time.

[0059] In the fourth step, when the magnesium and nickel reach a certain temperature, they melt. At this point, the rotating part 13 is activated first, and then the handwheel 10 is turned. The magnesium in crucible 6 and the nickel in crucible 7 can all flow into crucible 3 12. The two handwheels 10 can be operated independently. There are three ways to add magnesium and nickel to crucible 3 12: first, pour in molten magnesium and then pour in molten nickel; second, pour in molten nickel and then pour in molten magnesium; and third, pour in molten magnesium and molten nickel at the same time.

[0060] Fifth step: Molten magnesium and molten nickel are completely introduced into crucible three 12. After a period of time, the chiller 18 is started. After the chiller 18 runs for a period of time, the rotating part two 13 stops. Then, the telescopic cylinder 19 is controlled to move, so that crucible three 12 moves down. At this time, the operator can take out the magnesium-aluminum alloy in crucible three 12.

[0061] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0062] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
