Description

Technical Field

[0001] This application relates to the field of induction heating technology, and in particular to a counter-polar high-temperature superconducting magnet device and a superconducting induction heating equipment. Background Technology

[0002] Superconducting induction heating technology utilizes superconducting materials to achieve a resistance-free state at extremely low temperatures, thereby generating a strong magnetic field. When a metal rod, such as an aluminum rod, cuts magnetic field lines in this strong magnetic field, eddy currents are formed inside it. As these eddy currents flow inside the metal rod, a large amount of heat is generated due to the resistance, thus achieving the purpose of efficient heating.

[0003] In related technologies, superconducting induction heating equipment typically adopts a horizontal design, which is mainly suitable for heating workpieces placed horizontally. However, for working conditions requiring vertical placement or vertical heating, this traditional horizontal superconducting induction heating equipment often cannot meet the requirements, thus limiting its application range. At the same time, in related technologies, the iron core of the heating equipment is set with one magnetic pole fixed and the other magnetic pole moving. Since the center position of the two magnetic poles must remain unchanged, the range of movement of the other magnetic pole is limited unless the fixed magnetic pole iron core is removed and replaced with an iron core of a different size, which is quite complicated and cumbersome. As a result, the air gap adjustment of the equipment has significant limitations, with a small adjustment range, making it difficult to adapt to various working conditions and the processing needs of workpieces of different sizes. Summary of the Invention

[0024] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments.

[0025] Please see Figures 1 to 4This embodiment provides a counter-polarity high-temperature superconducting magnet device 100, which includes a bed base 10, a superconducting magnet assembly 20, and a core assembly 30. The bed base 10 is provided with a linear guide rail 11 arranged along a first direction A. Two mounting plates 12 are slidably connected to the linear guide rail 11, and support frames 13 are respectively provided at both ends of the bed base 10 near the linear guide rail 11. The superconducting magnet assembly 20 includes a counter-polarity superconducting magnet 21 disposed on the mounting plate 12 and a telescopic member 22 disposed on the support frame 13 and connected to the counter-polarity superconducting magnet 21 at its output end. The counter-polarity superconducting magnet 21 has a first through hole 211 along its central axis. The telescopic member 22 is used to control the two mirror-arranged superconducting magnets 21 to move towards or away from each other in the first direction A, so as to adjust the magnetic field strength of the magnetic field region 40 formed between the two superconducting magnets 21; the core assembly 30 includes a drive member 31 respectively disposed on the two support frames 13, a transmission screw 32 disposed on the output shaft of the drive member 31, and an iron core 33 passing through the first through hole 211; an adjustment blind hole 331 is opened along the central axis at one end of the iron core 33 near the drive member 31, and a part of the transmission screw 32 extends into the adjustment blind hole 331 and is connected to the iron core 33 in a transmission manner; the drive member 31 is used to control the two iron cores 33 to move towards or away from each other in the first direction A.

[0026] It should be noted that, for ease of description, in this embodiment, the length direction of the bed base 10 is defined as the first direction A, and the height direction of the bed base 10 is defined as the second direction B, that is, the first direction A and the second direction B are perpendicular. The linear guide rail 11 is installed on the top surface of the bed base 10 along the first direction A. In order to improve the stability of the sliding process after the superconducting magnet assembly 20 is installed, two linear guide rails 11 can be arranged parallel to each other at intervals on the top surface of the bed base 10. Two mounting plates 12 are slidably connected to the two linear guide rails 11 respectively, that is, the two mounting plates 12 can slide in opposite directions along the first direction A. Two support frames 13 are respectively set on the top surface of the bed base 10 and close to the two ends of the linear guide rails 11. At the same time, the two support frames 13 can be mirrored and fixedly connected to the bed base 10.

[0027] It should also be noted that the telescopic member 22 is arranged along the first direction A, with one end connected to the support frame 13 and the other end connected to the counter superconducting magnet 21. The telescopic member 22 controls the movement of the counter superconducting magnet 21. In order to ensure the stability of the counter superconducting magnet 21 during the adjustment process, a telescopic member 22 is arranged on both sides of each pair of counter superconducting magnets 21, that is, each pair of counter superconducting magnets 21 is controlled to move by two telescopic members 22. As for the driving member 31, it is connected to the adjustment blind hole 331 opened on the iron core 33 through the transmission screw 32. When the driving member 31 controls the transmission screw 32 to rotate, it controls the iron core 33 to move in the first direction A. That is, in this embodiment, the symmetrically arranged iron core 33 and counter superconducting magnet 21 can be moved independently. In this way, the air gap adjustment range is larger, so that the device can better adapt to various working conditions and workpieces of different sizes.

[0028] The high-temperature superconducting magnet device 100 provided in this application comprises two superconducting magnet assemblies 20 and two core assemblies 30. The two superconducting magnet assemblies 20 are slidably connected to the bed base 10 in a first direction A via guide rails. A magnetic field region 40 is formed between the two superconducting magnet assemblies 20. Each superconducting magnet assembly 20 includes a counter pole superconducting magnet 21 and a telescopic member 22. The telescopic member 22 drives the counter pole superconducting magnet 21 to move in the first direction A, thereby adjusting the distance between the two counter pole superconducting magnets 21 and thus adjusting the magnetic field strength of the magnetic field region 40. Simultaneously, the core assemblies 30 include driving members 31 respectively disposed on the two support frames 13 and... The iron core 33 is connected to the drive unit 31 and passes through the first through hole 211. The drive unit 31 controls the two iron cores 33 located on the same axis to move towards or away from each other in the first direction A, thereby realizing the adjustment of the magnetic field magnitude of the magnetic field region 40. The distance between the superconducting magnet 21 and the iron core 33 can be adjusted independently, so that different magnet spacing and iron core 33 spacing can be flexibly adjusted. The air gap adjustment range is larger and the adjustment is more convenient. Therefore, it can be used to study and realize various different magnetic field distributions, and thus realize applications under various different magnetic field distribution conditions. The device can take into account the heating needs of various specific working conditions such as horizontal, vertical placement or vertical heating.

[0029] Unlike traditional high-temperature superconducting magnets, the counter-polar high-temperature superconducting magnet device 100 in this embodiment symmetrically arranges two counter-polar superconducting magnets 21 and an iron core 33, enabling the formation of an adjustable strong magnetic field between the two counter-polar superconducting magnets 21. This allows the counter-polar high-temperature superconducting magnet device 100 to function in various environments, meeting diverse specific requirements. Furthermore, the magnetic field region 40 is compatible with various workstations, such as vertical and horizontal workstations, thus enabling it to handle various working conditions, such as single crystal growth, liquid metal solidification, and smelting operations. The vertical workstation design allows the equipment to operate stably in various environments, meeting diverse specific needs, thereby enhancing the device's versatility and practicality.

[0030] Please see Figure 1 In some embodiments, the telescopic member 22 includes a limiting connecting plate 221 with its two ends respectively connected to the counter superconducting magnet 21 and the mounting plate 12, and a hydraulic cylinder 222 disposed on the support frame 13. The hydraulic cylinder 222 is arranged along the first direction A and its output shaft is connected to the limiting connecting plate 221. Specifically, the two limiting connecting plates 221 are respectively installed on both sides of the counter superconducting magnet 21, thereby fixing the counter superconducting magnet 21 perpendicular to the first direction A. A hydraulic cylinder mounting support is provided on the support frame 13, and a hydraulic cylinder 222 connecting seat is provided on the limiting connecting plate 221. The hydraulic cylinder 222 is mounted on the hydraulic cylinder mounting support. At the same time, the output end of the hydraulic cylinder 222 is connected to the hydraulic cylinder connecting seat. The setting of the limiting connecting plate 221, on the one hand, further limits and fixes the position of the counter superconducting magnet 21, and on the other hand, ensures the synchronous movement of the counter superconducting magnet 21 and the mounting plate 12.

[0031] Please see Figure 2 and Figure 3 In some embodiments, the bed base 10 is provided with a loading channel 14, which is located in the middle area of ​​the linear guide rail 11 in the first direction A. At the same time, the loading channel 14 is located between the two linear guide rails 11 and is connected to the magnetic field region 40. When it is necessary to put the workpiece into the device for heating, it is more convenient to lift the workpiece from the bottom of the device to between the two counter pole superconducting magnets 21.

[0032] Please see Figure 3 and Figure 4 In some embodiments, two iron core assemblies 30 are disposed opposite to each other on the support frame 13 on both sides, and the corresponding two iron cores 33 are respectively inserted through the first through holes 211 on both sides and located on the same central axis. The support frame 13 is used to fix the driving member 31, which can be a motor as a power source. Setting the two iron cores 33 on the same central axis can ensure that a more uniform magnetic field is generated between the two superconducting magnets 21.

[0033] Furthermore, a fixing seat 121 is provided on the mounting plate 12 between the superconducting magnet assembly 20 and the support frame 13. The fixing seat 121 has a second through hole 1211 along the first direction A for supporting the iron core 33 to pass through. The second through hole 1211 is coaxially arranged with the first through hole 211. Specifically, the fixing seat 121 is located between the superconducting magnet assembly 20 and the support frame 13. The bottom of the fixing seat 121 can be fixedly connected to the mounting plate 12 by bolts. After the fixing seat 121 is installed, its second through hole 1211 is coaxially arranged with the first through hole 211. 1211 and the first through hole 211 are the same in outline size. The thickness of the fixed seat 121 in the first direction A can be determined according to the actual situation. When the iron core 33 is installed, the iron core 33 passes through the second through hole 1211 and the first through hole 211 in sequence, and the iron core 33 is slidably connected to the second through hole 1211. When controlling the iron core 33 to make large displacement adjustment, the fixed seat 121 can provide circumferential sliding support at the connection between the iron core 33 and the transmission screw 32, so that the iron core 33 only has the degree of freedom along the first direction A, so as to ensure that the iron core 33 can only move stably on the axis.

[0034] Continue reading Figure 4 Optionally, a lead screw nut 3311 is embedded in the opening of the adjustment blind hole 331 of the iron core 33. The transmission lead screw 32 is threadedly connected to the lead screw nut 3311 and extends into the adjustment blind hole 331. Specifically, the lead screw nut 3311 is coaxially embedded in the opening of the adjustment blind hole 331. After the transmission lead screw 32 cooperates with the lead screw nut 3311, it extends into the adjustment blind hole 331. With this configuration, the rotation of the transmission lead screw 32 is converted into the linear movement of the iron core 33 through the transmission cooperation between the transmission lead screw 32 and the lead screw nut 3311. This reduces the space occupied by the device on the one hand, and increases the travel of the iron core 33 controlled by the transmission lead screw 32 on the other hand, thereby increasing the adjustment range of the air gap. Continue reading Figure 4In some embodiments, the drive unit 31 includes a servo motor 311, a reducer 312 connected to the output end of the servo motor 311 and mounted on the support frame 13, and the end of the reducer 312 facing away from the servo motor 311 being connected to one end of a lead screw via a coupling 313. Specifically, a third through hole (not shown in the figure) is provided on the support frame 13, and a mounting seat 131 is provided at the outer end of the third through hole. The mounting seat 131 is used to mount and fix the reducer 312, wherein the interior of the mounting seat 131... A through cavity is provided to connect to the third through hole. A lead screw bearing seat 321 is provided at the inner end of the third through hole. The transmission lead screw 32 passes through the lead screw bearing seat 321 and the third through hole in sequence and extends into the through cavity. It is connected to the end of the reducer 312 away from the servo motor 311 through the coupling 313. During the adjustment of the movement of the iron core 33, the power is provided by the servo motor 311 and reduced by the reducer 312, which increases the torque. This can drive the transmission lead screw 32 to rotate, and then drive the iron core 33 to move in the first direction A.

[0035] In one example, a receiving cavity can be provided on the inner end of the support frame 13 near the third through hole. This receiving cavity is at the same height as the second through hole 1211, and its projected profile along the first direction A is larger than the projected profile of the iron core 33. This arrangement allows the iron core 33 to have a larger adjustment range within a limited space. For example, the movement range of the iron core 33 relative to the superconducting magnet 21 can be 0-200mm.

[0036] Please see Figure 5 and Figure 6 In some embodiments, the counterpolar high-temperature superconducting magnet device 100 further includes a top bracket 50 covering the magnetic field region 40 and connected at both ends to the top of the support frame 13. A vertical spindle box 51 is disposed above the magnetic field region 40 on the top bracket 50. The output shaft of the vertical spindle box 51 extends along the second direction B into the magnetic field region 40, and a vertical clamp 511 is disposed at its end. The vertical spindle box 51 is configured to control the rotation of the vertical clamp 511 to fix the workpiece to be heated and rotate it for heating. Specifically, the vertical spindle box... A synchronous pulley 512 is provided at one end of the vertical fixture 511 away from the vertical fixture 511. The synchronous pulley 512 is connected to the vertical motor 521 via a transmission belt 5211. The vertical motor 521 is mounted on a motor bracket 52 on the bed base 10, so that the output shaft of the vertical motor 521 and the synchronous pulley 512 are at the same height. With this configuration, the vertical motor 521 controls the rotation of the vertical fixture 511 through the vertical spindle box 51, thereby fixing and rotating the structural component to be heated in the magnetic field region 40.

[0037] Please see Figure 7 and Figure 8In some embodiments, the superconducting magnet 21 includes a Dewar structure 212, a cold shield structure 213, a coil structure 214, and a cooling structure 215. The Dewar structure 212 is provided with a first annular cavity 2121 surrounding and spaced apart from the first through hole 211. The cold shield structure 213 is provided in the first annular cavity 2121 and is provided with a second annular cavity 2131 surrounding the first through hole 211. The coil structure 214 is provided in the second annular cavity 2131. The cooling structure 215 is provided on the Dewar structure 212 and the cold head at the output end is connected to the cold shield structure 213 and the coil structure 214 respectively.

[0038] It should be noted that in this embodiment, the first through hole 211 and the first annular cavity 2121 can be completely separated by a partition. The cold screen structure 213 is coaxially sleeved in the first annular cavity 2121, that is, the Dewar structure 212 completely seals the cold screen structure 213 in the first annular cavity 2121. The cold screen structure 213 is similar in structure to the Dewar structure 212, that is, both the cold screen structure 213 and the Dewar structure 212 are arranged in annular shape. When the cold screen structure 213 is installed in the Dewar structure 212, the projection contour of the second annular cavity 2131 along the axial direction is located in the first annular cavity 2121.

[0039] Furthermore, the coil structure 214 includes a support frame (not shown in the figure) and a double-panel coil (not shown in the figure). It should be understood that, unlike the high-temperature superconducting magnets in the prior art, the high-temperature superconducting magnet coils in the prior art are precisely wound layer by layer in a solenoid winding manner. This arrangement results in very small gaps between coil layers. Under normal circumstances, there are about one hundred layers in the solenoid winding method, and this solenoid winding method is stacked together as a whole, which makes it difficult for the curing material of the curing process to penetrate. If the coil as a whole is not completely cured, it will be difficult to eliminate the gaps between the superconducting tapes, thereby seriously affecting the coil's heat conduction and overall strength. Thus, it is difficult to operate for a long time in strong magnetic field and high field scenarios, such as in some conditions where the maximum magnetic field needs to be greater than 3T.

[0040] In this embodiment, the coil structure 214 is formed by a supporting frame and a double-panel coil. The double-panel coils are stacked to form a whole. The two sides of the double-panel coils are open, so the curing material can penetrate into the two layers of superconducting tape more easily during the curing process. This structure also simplifies the curing process of the double-panel coils, making the curing process more convenient. At the same time, the upper and lower surfaces of the double-panel coils are flatter after curing, and there are no gaps when the double-panel coils are stacked together. This improves the cooling effect of the coil structure 214, increases the overall strength of the coil structure 214, and allows it to maintain high-field steady-state (superconducting state) operation for a longer time and generate a stronger magnetic field.

[0041] It should be explained that, in this embodiment, the Dewar structure 212 is used to bear the weight and electromagnetic force of the coil structure 214. That is, after the coil structure 214 is installed in the cold shield structure 213, it is fixedly connected to the Dewar structure 212, thereby keeping the coil structure 214 fixed after installation and keeping the coil structure 214 in a vacuum state to reduce heat convection. The cold shield structure 213 is used to reduce heat radiation to the coil structure 214 and keep the coil structure 214 in a low-temperature working environment. The output end of the refrigerator of the cooling structure 215 is connected to the cold shield structure 213 and the coil structure 214 respectively, so as to achieve more uniform and efficient cooling of the coil structure 214, so as to keep the superconducting tape in a superconducting state.

[0042] In some embodiments, the high-temperature superconducting magnet device based on the above embodiments can meet, but is not limited to, the following application scenarios in practical applications, as shown in Table 1. Thanks to the independently adjustable distance between the superconducting magnet assembly 20 and the core assembly 30, this feature allows for flexible adjustment of different spacings between the superconducting magnet assemblies 20 and the core 30 in practical applications, thereby enabling the study and realization of various magnetic field distributions. This flexibility allows the device to be used under a variety of different magnetic field distribution conditions, thus meeting various specific operating requirements.

[0043] Table (1) provides the application conditions of the polarized high-temperature superconducting magnet in this embodiment.
