Abstract
Description
Technical Field
[0001] This invention relates to the field of superconducting magnet technology, and in particular to a method for preparing a superconducting magnet assembly and the superconducting magnet assembly itself. Background Technology
[0002] In related technologies, a transverse superconducting magnetic field is used to forcefully control the thermal convection of the melt, thereby controlling the dissolution rate and amount of oxygen in the crucible, reducing the impurity content of the crystal, reducing the non-uniformity of longitudinal and radial impurity distribution, and obtaining a high-quality single crystal, thus meeting the requirements for semiconductor chips.
[0003] Currently, two methods can be used to form a transverse superconducting magnetic field: one is to use a four-coil structure to form the transverse magnetic field, such as... Figure 1 As shown, one method uses four circular solenoid superconducting coils symmetrically arranged at a certain angle (100') to form a transverse magnetic field, obtained through simulation software. Another method uses a pair of saddle-shaped coil frames to form a transverse magnetic field. The four-coil structure is complex and has low magnetic field utilization. The transverse superconducting magnetic field formed by the saddle-shaped coil frame has a better uniformity and crystal pulling effect. In a transverse field with a central field strength of 4500 GS, the magnetic superconducting wire used with the saddle-shaped coil frame structure requires 1 / 3 less magnetic superconducting wire than the transverse four-coil structure, greatly saving wire costs.
[0004] The preparation method of saddle-shaped coils includes: first, winding the superconducting wire into a rectangular frame, and then bending the coil frame into a saddle shape. During this operation, the superconducting wire is prone to breakage under bending and tension, affecting its performance and even leading to scrapping, which increases the risk in the production process and increases the manufacturing cost. Summary of the Invention
[0005] The purpose of this invention is to provide a method for preparing a superconducting magnet assembly and a superconducting magnet assembly, which reduces the risk of superconducting wire breakage during the production process and reduces manufacturing costs.
[0006] To achieve this objective, the present invention adopts the following technical solution:

[0009] The magnet frame is bent so that it is saddle-shaped and the two sides are bent at a predetermined angle.
[0010] The superconducting wire is wound around the outer circumferential surface of the magnet frame.
[0011] In some possible implementations, when processing the magnet skeleton to a predetermined shape, the process further includes: providing a plurality of grooves on the outer peripheral surface, the plurality of grooves being arranged along a direction from one side to another, and the superconducting wire being disposed in the plurality of grooves.
[0012] In some possible implementations, after machining the magnet skeleton to a predetermined shape and before bending the magnet skeleton, the method further includes: adding a fixing agent in the wire groove;

[0014] In some possible implementations, when processing the magnet skeleton to a preset shape, the process further includes: providing a first jumper groove on the outer peripheral surface of the magnet skeleton, the first jumper groove being connected to a plurality of wire grooves, and when the superconducting wire is wound around the outer peripheral surface of the magnet skeleton, the superconducting wire enters the wire groove from the first jumper groove.
[0015] In some possible implementations, when processing the magnet skeleton to a predetermined shape, the method further includes: providing the outer peripheral surface of the magnet skeleton with the first jumper groove and the second jumper groove at intervals, wherein the second jumper groove is connected to all of the plurality of wire grooves; and when the magnet skeleton is wound to form a layer of the superconducting wire, the method further includes:
[0016] The superconducting wire enters the wire groove from the first jumper groove, and the superconducting wire is wound around the multiple wire grooves in a direction from one side to the other.
[0017] After the last wire groove is wound around, the superconducting wire enters the second jumper groove;
[0018] The superconducting wire enters the wire groove from the second jumper groove, and the superconducting wire is wound around the multiple wire grooves in a direction from one side to the other.
[0019] In some possible implementations, when processing the magnet skeleton to a preset shape, the process further includes: providing an opening on the side of the magnet skeleton that communicates with the wire groove, the opening being located in the outer peripheral direction of the magnet skeleton between the first jumper groove and the second jumper groove, and when the superconducting wire is wound around the outer peripheral surface of the magnet skeleton, the superconducting wire enters and exits from the opening.
[0020] In some possible implementations, the width of the opening is not less than the minimum bending radius of the superconducting wire.
[0021] In some possible implementations, fins are formed between two adjacent grooves, a plurality of fins are parallel, and the thickness of the fins is 1mm-3mm; and / or, the spacing between two adjacent fins is 2mm-4mm.
[0022] In some possible implementations, when the superconducting wire is wound around the outer peripheral surface of the magnet frame, it includes:
[0023] A layer of the superconducting wire is formed by winding it around the magnet frame;
[0024] An adhesive layer is coated onto the superconducting wire;
[0025] The superconducting wire is wound around the adhesive layer to form another layer of superconducting wire, so that the two adjacent layers of superconducting wire are bonded together through the adhesive layer.

[0027] The beneficial effects of this invention are:
[0028] This invention provides a method for fabricating a superconducting magnet assembly and the assembly itself. The superconducting magnet assembly is fabricated by first forming the magnet and then winding it with superconducting wires. Compared to existing technologies, this method avoids subjecting the superconducting wires to bending and tensile forces, thus preventing breakage or splitting and protecting the wires. This reduces production risks and lowers manufacturing costs. In comparison, under the condition of equal central field strength, the saddle-shaped coil exhibits more uniform magnetic field at the center of the superconducting magnet assembly compared to the four-coil structure, resulting in better crystal pulling. Furthermore, the repulsive force between adjacent coils is significantly reduced, increasing system stability. Additionally, the amount of wire used is smaller, saving on the cost of the superconducting magnet assembly's wires. Attached Figure Description

[0041] like Figures 2-7 As shown, this embodiment provides a superconducting magnet assembly, including a magnet frame 1 and a superconducting wire 2 wound around the magnet frame 1. This embodiment also provides a method for fabricating the superconducting magnet assembly, including the following steps:
[0042] S1. Process the magnet frame 1 to a preset shape. The magnet frame 1 includes two opposing side surfaces 11 and outer peripheral surfaces surrounding the two side surfaces 11. For example, the magnet frame 1 is made of a heavy rectangular aluminum plate, such as 5083 aluminum, and is machined to a preset rectangular shape with a rectangular through hole in the middle. The roughness and flatness of the rectangular plate meet the requirements. Among them, the two surfaces in the thickness direction are the side surfaces 11, and the other four surfaces are the outer peripheral surfaces. A rounded corner is provided between any two adjacent side surfaces 11.
[0043] S2. Bending the magnet frame 1 to make the magnet frame 1 saddle-shaped, with the two sides 11 at a preset bending angle; optionally, the preset bending angle is 45°-135°, such as 45°, 60°, 90° or 135°, etc., which can refer to the existing technology and are not limited.
[0044] S3. The superconducting wire 2 is wound around the outer circumference of the magnet frame 1 to form a saddle-shaped coil.
[0045] By first shaping the superconducting magnet and then winding the superconducting wire 2 around it, the superconducting magnet assembly 100 can be prepared. Compared with existing technologies, this avoids the superconducting wire 2 from being subjected to bending and tensile forces, thereby preventing breakage or splitting and protecting the superconducting wire 2. This reduces the risks in the production process and thus lowers manufacturing costs. Figure 2 The image shows a schematic diagram of the transverse magnetic field formed by two superconducting magnet components 100 obtained through simulation software. The two superconducting magnet components 100 are symmetrically distributed. Figure 1 A schematic diagram of the transverse magnetic field formed by two turns of four circular solenoid superconducting wires is shown, comparing the two under the condition of equal central field strength. The comparison reveals that, at the center of the magnetic field, the saddle-shaped coil exhibits more uniform magnetic field uniformity and better crystal pulling effect compared to the four-coil design. Furthermore, the repulsive force between adjacent coils is significantly reduced, increasing the system's operational stability. Additionally, the amount of wire used is smaller, saving on the wire cost of the superconducting magnet assembly 100. Generally, the superconducting wire 2 is formed by combining multiple strands of niobium-titanium superconducting wires, reducing the amount of superconducting wire 2 used and thus reducing the amount of rare metals used.
[0046] A rounded corner is provided between two adjacent side surfaces 11, that is, the two adjacent side surfaces 11 are smoothly transitioned, so that the outer peripheral surface is formed as a smooth surface, which facilitates the subsequent winding of the superconducting wire 2 and avoids the breakage of the superconducting wire 2.
[0047] When machining the magnet skeleton 1 to the preset shape, the process also includes: providing multiple grooves 12 on the outer peripheral surface, with the grooves 12 arranged along a direction from one side 11 to another, and the superconducting wire 2 disposed in the grooves 12. Specifically, the magnet skeleton 1 to the preset shape and the grooves 12 can be machined using a milling machine or other lathe, achieving one-time machining and avoiding the need to machine the grooves 12 again after bending, reducing the number of clamping operations and improving machining efficiency. The grooves 12 can limit the positioning of the superconducting wire 2, improving installation accuracy and stability. Fins 16 are formed between two adjacent grooves 12, with multiple parallel fins 16. The thickness of the fins 16 is 1mm-3mm, specifically 1mm, 2mm, or 3mm, etc., and the spacing between two adjacent fins 16 is 2mm-4mm, specifically 2mm, 3mm, or 4mm, etc., which can be set according to the outer diameter of the superconducting wire 2. Optionally, the outer diameter of the superconducting wire 2 and the spacing between the fins 16 are the same, for example, both are 3mm. The depth of the fin 16 can be determined according to the total height of the superconducting wire 2, that is, the depth of the wire groove 12 can be set according to the number of layers of the superconducting wire 2 and the outer diameter of the superconducting wire 2.
[0048] In one embodiment, when machining the magnet skeleton 1 to a preset shape, the process further includes: providing a first jumper groove 13 on the outer peripheral surface of the magnet skeleton 1, the first jumper groove 13 being connected to multiple wire grooves 12; and when the superconducting wire 2 is wound around the outer peripheral surface of the magnet skeleton 1, the superconducting wire 2 enters the wire groove 12 from the first jumper groove 13. By machining the magnet skeleton 1 and the first jumper groove 13 in one operation on the machine tool, the number of clamping operations on the machine tool is reduced, improving work efficiency.
[0049] During winding, the superconducting wire 2 enters the Nth slot 12 near one side 11 from the first jumper slot 13. After winding once in the Nth slot 12, the superconducting wire 2 re-enters the first jumper slot 13, then winds in the (N+1)th slot 12, and so on, until it is wound in the Mth slot 12 near the other side 11. For example, multiple slots 12 are numbered sequentially along the direction from one side 11 to the other, as the first slot 121, the second slot, and so on, until the last slot 122. The superconducting wire 2 enters the first slot 121 from the first jumper slot 13, winds once in the first slot 121, re-enters the first jumper slot 13, then enters the second slot, winds once in the second slot, and re-enters the first jumper slot 13, and so on, until the last slot 122 is wound.
[0050] Optionally, insulation treatment is applied to the magnet frame 1 before winding the superconducting wire 2. Optionally, special treatment is applied to the intersection point where the superconducting wire 2 enters the second slot from the first slot 121.
[0051] When machining the magnet skeleton 1 to a preset shape, the process further includes: providing a first jumper groove 13 and a second jumper groove 14 at intervals on the outer peripheral surface of the magnet skeleton 1, with the second jumper groove 14 communicating with multiple wire grooves 12. By machining the magnet skeleton 1, the first jumper groove 13, and the second jumper groove 14 on the machine tool in one operation, the number of clamping operations on the machine tool is reduced, improving work efficiency. When the magnet skeleton 1 is wound to form a layer of superconducting wire 2, the following steps are included:
[0052] S31, the superconducting wire 2 enters the wire groove 12 from the first jumper groove 13, so that the superconducting wire 2 is wound around the multiple wire grooves 12 in the direction from one side 11 to the other side 11; for example, the superconducting wire 2 enters the first wire groove 121 from the first jumper groove 13, wound around the first wire groove 121 once and then enters the first jumper groove 13 again, then enters the second wire groove, wound around the second wire groove once and then enters the first jumper groove 13 again, and so on, until it is wound around the last wire groove 122.
[0053] S32. After winding around the last wire groove 122, the superconducting wire 2 enters the second jumper groove 14;
[0054] S33. The superconducting wire 2 enters the wire slot 12 from the second jumper slot 14, so that the superconducting wire 2 is wound around multiple wire slots 12 in a direction from one side 11 to the other side 11. For example, the superconducting wire 2 enters the last wire slot 122 from the second jumper slot 14, winds around the last wire slot 122 once, and then enters the second jumper slot 14 again, then enters the second to last wire slot, winds around the second to last wire slot once, and then enters the second jumper slot 14 again, and so on, until it winds around the first wire slot 121, thus completing one layer of superconducting wire 2 winding. Similarly, by repeating the above steps, multiple layers of superconducting wire 2 winding, such as the second layer, can be formed. This winding method ensures that the current direction of the two turns of superconducting wire 2 is consistent and the field shape is uniform when generating a magnetic field.
[0055] Furthermore, when the superconducting wire 2 is wound around the outer peripheral surface of the magnet frame 1, the following steps are included:
[0056] S310. A layer of superconducting wire 2 is formed by winding it around the magnet frame 1, specifically including steps S31, S32 and S33.
[0057] S320. Coat the superconducting wire 2 with an adhesive layer, which may be an epoxy resin layer.
[0058] S330, superconducting wire 2 is wound around the adhesive layer to form another layer of superconducting wire 2, so that the two adjacent layers of superconducting wire 2 are bonded together through the adhesive layer. The two adjacent layers of wire are bonded together with epoxy resin until the designed height is reached. Finally, the coil is inspected to check for any winding problems. If there are no problems, it is placed in a constant temperature chamber for curing to ensure structural stability.
[0059] When processing the magnet frame 1 to a preset shape, the process further includes: providing an opening 15 on the side 11 of the magnet frame 1 that communicates with the wire groove 12. The opening 15 is located on the outer periphery of the magnet frame 1 between the first jumper groove 13 and the second jumper groove 14, allowing for one-time processing and improving processing efficiency. When the superconducting wire 2 is wound around the outer periphery of the magnet frame 1, the superconducting wire 2 enters and exits through the opening 15. The position of the opening 15, located precisely between the first jumper groove 13 and the second jumper groove 14, not only facilitates the entry of the superconducting wire 2 but also allows for convenient exit after winding. The width of the opening 15 is not less than the minimum bending radius of the superconducting wire 2. For example, if the minimum bending radius of the superconducting wire 2 during entry and exit is 15mm, then the width of the opening 15 is greater than or equal to 15mm, preventing problems caused by the superconducting wire 2 being bent.
[0060] Optionally, the edges of the first jumper groove 13, the second jumper groove 14, the opening 15, and the fin 16 are all chamfered, such as rounded corners, R=0.3mm, to avoid burrs from scratching the superconducting wire 2 during winding.
[0061] After machining the magnet skeleton 1 to the preset shape and before bending the magnet skeleton 1, the process includes adding a fixing agent inside the wire groove 12. After bending the magnet skeleton 1 and the superconducting wire 2 is wound between the outer peripheral surfaces of the magnet skeleton 1, the process also includes removing the fixing agent inside the wire groove 12. After machining all the wire grooves 12, the bending process is prepared. Before bending, a fixing agent is added to the wire groove 12 to prevent the bending process from changing the width of the wire groove 12 and causing deformation. Then, a custom-made mold is used to bend the magnet skeleton 1 to avoid damaging the machined fins 16. During the bending process, the bending angle of each magnet skeleton 1 is ensured to reach the preset angle. After bending, the magnet skeleton 1 is heat-treated to relieve stress and ensure dimensions. Then, the fixing agent in the wire groove 12 is removed.
[0062] like Figure 6 and Figure 7 As shown, optionally, a winding device is used to wind the superconducting wire 2 onto the magnet skeleton 1. The magnet skeleton 1 is held by a skeleton clamp 201. The spindle of the active machine tool 203 drives the skeleton clamp 201 to rotate, thereby rotating the magnet skeleton 1. The active machine tool 203 and the skeleton clamp 201 can ensure the symmetry and centering of the magnet skeleton 1. The winding machine 202 is located on one side of the active machine tool 203. The winding machine 202 is used to wind the superconducting wire 2 sequentially into the wire groove 12. Optionally, the winding can be done manually, without limitation.
