Description

Technical Field

[0001] This invention relates to the field of metal smelting equipment technology, and more particularly to a superconducting smelting equipment in which a permanent magnet hollow motor drives a low-temperature superconducting coil to rotate. Background Technology

[0002] Metal smelting is a key basic process for obtaining high-performance alloy materials in strategic industries such as aerospace, new energy, and high-end equipment manufacturing. The quality of the smelting process directly affects the material's compositional uniformity, impurity content, grain structure, and final mechanical properties. Traditional smelting methods rely on thermal radiation or electric arc heat transfer, with heat conducted from the surface of the furnace charge to the interior. This results in low thermal efficiency, significant energy loss, and a high risk of introducing impurities. Electrodes, crucibles, and refractory materials are prone to reacting with or detaching from the metal at high temperatures, leading to alloy contamination. This is particularly problematic for highly reactive materials such as titanium alloys and high-temperature alloys. Furthermore, traditional heating methods struggle to achieve precise control of the internal temperature field of the molten pool, easily causing localized overheating or temperature gradients, which can lead to quality problems such as compositional segregation and coarse grains. Summary of the Invention

[0003] The purpose of this invention is to solve the problems of significant impact on highly reactive materials such as titanium alloys and high-temperature alloys in the prior art, and the difficulty in achieving precise control of the internal temperature field of the molten pool by traditional heating methods. The invention proposes a superconducting melting equipment with a permanent magnet hollow motor driving the rotation of a low-temperature superconducting coil.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A superconducting melting device that drives a low-temperature superconducting coil to rotate using a permanent magnet hollow motor includes a support base. A rotating connecting seat is fixedly connected to the top of the support base. A standing platform is mounted on the top of the rotating connecting seat. A superconducting melting shell is fixedly connected to the inner side of the standing platform. A melting crucible is fixedly connected inside the superconducting melting shell. A slip ring fixing flange is mounted on the outer side of the melting crucible. A hollow motor is mounted on the outer side of the slip ring fixing flange. A hollow motor rotor is mounted inside the hollow motor. A low-temperature superconducting coil is mounted inside the hollow motor rotor. Current is passed through the low-temperature superconducting coil to form a constant magnetic field and generate stable rotating magnetic lines of force as it rotates, generating induced eddy currents inside the metal ingot for self-heating and melting.

[0005] Preferably, a conductive slip ring is installed inside the superconducting melting shell, and the conductive slip ring is located on the outside of the melting crucible and below the hollow motor component.

[0006] Preferably, a device frame is fixedly connected to the top surface of the support base, a magnet cooling module is fixedly connected inside the device frame, and a helium gas pipe is installed at the top of the magnet cooling module.

[0007] Preferably, the inner side of the support base is fixedly connected with a mounting bracket, and there are two mounting brackets in total, which are symmetrically fixed on the front and rear sides of the top surface of the support base.

[0008] Preferably, a lifting cylinder is hinged to the inner side of each of the two mounting supports, and a connecting support plate is installed on the side of the lifting cylinder facing away from the mounting support. The side of the connecting support plate facing away from the lifting cylinder is connected to the standing platform.

[0009] Preferably, a connecting end seat is fixedly connected to the top of the superconducting melting shell, the connecting end seat passes through the standing platform to the upward side, and a discharge guide seat is fixedly connected to one end of the connecting end seat, the discharge guide seat communicating with the connecting end seat.

[0010] Preferably, when the lifting cylinder is in the upward output state, the standing platform is in the state of being pushed outward by the lifting cylinder around the rotating connecting seat, and is in the state of synchronously driving the superconducting melting shell to rotate.

[0011] Preferably, a superconducting magnet located outside the melting crucible is fixedly connected inside the superconducting melting shell, and one end of the superconducting magnet is fixedly connected to a magnetohydrodynamic fixing flange.

[0012] Preferably, the superconducting melting shell is internally fixedly connected to a magnetohydrodynamic seal for sealing the superconducting magnet.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In this invention, through the linkage between a hollow motor and a low-temperature superconducting coil, when the hollow motor drives the hollow motor rotor to rotate, the hollow motor rotor drives the low-temperature superconducting coil to rotate synchronously, so that the low-temperature superconducting coil directly generates a dynamic rotating magnetic field, thereby forming a uniform rotating magnetic field inside the melting crucible. This rotating magnetic field directly acts on the stationary metal ingot, causing it to generate induced eddy currents and self-heat to melt. Through the synergistic effect of the hollow motor and the low-temperature superconducting coil, the metal ingot can complete the transformation from solid to liquid state in a completely non-contact state, avoiding the problem of impurity introduction caused by direct contact between the electrodes, crucibles and other components and the molten metal in traditional melting methods, and realizing the clean melting of highly active and high-purity metals.

[0014] 2. In this invention, a stable magnetic field is generated by rotating a low-temperature superconducting coil under a constant current. This prevents magnetic field cutting and mutual interference with a stationary superconducting magnet. Combined with the synergistic protection of the magnet cooling module and the magnetohydrodynamic seal, the low-temperature superconducting coil can maintain stable superconducting performance and generate a high-intensity dynamic magnetic field while rotating. It strictly follows the design principles of rotating superconducting components, avoiding the superconducting coil being in an alternating magnetic field, thus fundamentally eliminating the risk of quench failure and thermal accidents. This magnetic field forms a uniformly distributed induced eddy current field inside the melting crucible, enabling the metal ingot to obtain a balanced heat input from the inside out during the melting process. The uniformity of the temperature field distribution inside the molten pool is significantly improved, solving the problems of uneven magnetic field distribution, local overheating, and component segregation in traditional heating methods, and improving the internal quality and microstructure uniformity of the ingot.

[0015] 3. In this invention, through the coordinated operation of the lifting cylinder, the standing platform, and the superconducting melting shell, when the lifting cylinder outputs upward through the connecting support plate, the standing platform unfolds outward around the rotating connecting seat under the push of the lifting cylinder. The unfolding action of the standing platform synchronously causes the superconducting melting shell fixedly connected to it to tilt, so that the molten metal inside the melting crucible flows into the discharge guide seat along the connecting end seat under the action of gravity and completes the discharge. Through the synergistic effect of the lifting cylinder and the standing platform, the melting and discharge processes can be seamlessly connected without transferring the crucible or changing the metal state. This solves the problem that existing superconducting heating devices cannot be directly applied to liquid metal melting and discharge operations due to their fixed structure, and improves the ease of operation and melting efficiency of the equipment.

[0016] 4. In this invention, a hollow motor drives a hollow motor rotor to rotate, which in turn drives a low-temperature superconducting coil to rotate synchronously. The rotation of the low-temperature superconducting coil forms a stable rotating magnetic field, causing uniformly distributed induced eddy currents to be generated inside a stationary metal ingot, resulting in self-heating and melting. This achieves non-contact heating, avoiding the contamination problems caused by contact between electrodes, crucibles, and other components and the molten metal in traditional smelting. Furthermore, this design prevents the superconducting coil from being in an alternating magnetic field, eliminating the risk of ignition failure. A lifting cylinder pushes a standing platform to unfold outwards around a rotating connecting seat. The standing platform simultaneously tilts the superconducting smelting shell, allowing the molten metal inside the smelting crucible to be smoothly discharged through the connecting end seat and the discharge guide seat. This achieves seamless connection between the smelting and discharge processes. This device, through the coordinated operation of direct eddy current heating with a rotating magnetic field and tilting discharge, solves the problems of existing superconducting heating technologies being prone to ignition failure and unsuitable for direct application in liquid metal smelting and discharge operations, thus improving the purity and ease of operation of the smelting process.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0020] Example, refer to Figure 1 - Figure 8A superconducting smelting device that drives a low-temperature superconducting coil to rotate using a permanent magnet hollow motor includes a support base 1. A rotating connecting seat 3 is fixedly connected to the top of the support base 1. A standing platform 301 is mounted on the top of the rotating connecting seat 3. A superconducting smelting shell 4 is fixedly connected to the inner side of the standing platform 301. A smelting crucible 5 is fixedly connected inside the superconducting smelting shell 4. A slip ring fixing flange 501 is mounted on the outer side of the smelting crucible 5. A hollow motor element 5011 is mounted on the outer side of the slip ring fixing flange 501. A hollow motor rotor 50111 is mounted inside the hollow motor element 50111. A low-temperature superconducting coil element 50112 is mounted inside the hollow motor rotor 50111. Current is passed through the low-temperature superconducting coil element 50112 to form a constant magnetic field, which generates stable rotating magnetic lines of force 50114 as it rotates. The coil is used to smelt metal ingots 5011. 3. The internal induced eddy current self-heating melting is generated. The superconducting melting shell 4 is equipped with a conductive slip ring 5012. The conductive slip ring 5012 is set on the outside of the melting crucible 5 and below the hollow motor element 5011. The top surface of the support base 1 is fixedly connected to the equipment frame 101. The inside of the equipment frame 101 is fixedly connected to the magnet cooling module 1011. The top of the magnet cooling module 1011 is equipped with a helium gas pipe 10111. This realizes non-contact heating of the metal ingot 50113 by generating magnetic lines of force 50114 using the rotating low-temperature superconducting coil element 50112, which effectively avoids the introduction of impurities and improves the heating efficiency. The inner side of the support base 1 is fixedly connected to the mounting support 2. There are two mounting supports 2. The two mounting supports 2 are symmetrically fixed on the front and rear sides of the top surface of the support base 1.

[0021] Furthermore, lifting cylinders 201 are hinged to the inner sides of both mounting supports 2. A connecting support plate 2011 is installed on the side of the lifting cylinder 201 facing away from the mounting support 2. The side of the connecting support plate 2011 facing away from the lifting cylinder 201 is connected to the standing platform 301. A connecting end seat 401 is fixedly connected to the top of the superconducting melting shell 4. The connecting end seat 401 passes through the standing platform 301 upwards. A discharge guide seat 4011 is fixedly connected to one end of the connecting end seat 401. The discharge guide seat 4011 and the connecting end seat 401 are in communication, realizing stable power supply and signal transmission to the hollow motor component 5011 and the low-temperature superconducting coil component 50112, ensuring the electrical connection reliability of the rotating components in continuous working state. When the lifting cylinder 201 is in the upward output state, the standing platform 301 is pushed by the lifting cylinder 201 to unfold outwards around the rotating connecting seat 3, and is in a state of synchronously driving the superconducting melting shell 4 to rotate.

[0022] Furthermore, a superconducting magnet 6 is fixedly connected inside the superconducting melting shell 4, located outside the melting crucible 5. One end of the superconducting magnet 6 is fixedly connected to a magnetic fluid fixing flange 601, and a magnetic fluid seal 6011 for sealing the superconducting magnet 6 is fixedly connected inside the superconducting melting shell 4, thereby achieving efficient cooling of the superconducting magnet 6. A cooling medium is introduced through a helium gas pipe 10111 to ensure that the superconducting material is maintained in a low-temperature working state.

[0023] In use, the metal ingot 50113 to be melted is first placed inside the melting crucible 5. The melting crucible 5 is fixedly connected to the inside of the superconducting melting shell 4, providing space for the metal ingot 50113 and serving as a heat transfer carrier. Then, the hollow motor element 5011, mounted on the outside of the slip ring fixing flange 501, is activated. The slip ring fixing flange 501, mounted on the outside of the melting crucible 5, provides a stable mounting base for the hollow motor element 5011. The hollow motor element 5011 serves as the drive source, and its internal components are... There is a hollow motor rotor 50111. When the hollow motor element 5011 is energized and started, it generates a rotational driving force. This driving force acts directly on the hollow motor rotor 50111, causing it to rotate at high speed around its axis. The rotational motion of the hollow motor rotor 50111 is transmitted to the cryogenic superconducting coil element 50112 installed inside it through a mechanical connection structure. Since the cryogenic superconducting coil element 50112 is fixedly installed on the hollow motor rotor 50111... Internally, the cryogenic superconducting coil 50112 and the hollow motor rotor 50111 rotate synchronously, with no relative motion between them, thus achieving efficient transmission of driving force. During rotation, a direct current flows through the cryogenic superconducting coil 50112, causing it to generate a stable and strong magnetic field. This magnetic field rotates synchronously with the rotation of the cryogenic superconducting coil 50112, forming a rotating magnetic field environment. Simultaneously, a superconducting melting shell 4 is fixedly connected internally to the coil. The superconducting magnet 6 is located outside the melting crucible 5. Under the cooling effect of the magnet cooling module 1011, the superconducting magnet 6 is maintained in a superconducting state and generates a static strong magnetic field. When the low-temperature superconducting coil 50112 is driven by the hollow motor rotor 50111 to rotate, the low-temperature superconducting coil 50112 rotates synchronously with the hollow motor rotor 50111, directly forming a high-intensity rotating magnetic field. This rotating magnetic field acts independently on the metal ingot 50113 without relative cutting with the static magnetic field of the superconducting magnet 6.The rotating magnetic field directly penetrates the metal ingot 50113 and induces eddy currents within it. These eddy currents generate Joule heating, achieving self-heating. Structurally, this avoids placing the superconducting coil in an alternating magnetic field, eliminating the risk of quench failure and thermal accidents. A high-intensity and uniformly distributed rotating magnetic field region is formed inside the melting crucible 5. The metal ingot 50113, placed inside the melting crucible 5, is located at the center of this rotating magnetic field region. Since the metal ingot 50113 is a conductive material, when the rotating magnetic field penetrates it, according to the principle of electromagnetic induction, an induced current is generated inside the metal ingot 50113. The induced electromotive force forms eddy currents inside the metal ingot 50113. Under the resistance of the metal ingot 50113, the eddy currents generate Joule heating, which causes the temperature of the metal ingot 50113 to rise rapidly. Since the eddy currents are generated inside the metal ingot 50113, the heat is conducted from the inside of the metal ingot 50113 to the outside, achieving a heating effect from the inside out. With the continuous action of the rotating magnetic field, eddy currents are continuously generated, heat is continuously accumulated, and the temperature of the metal ingot 50113 continues to rise until it reaches the melting temperature, changing from solid to liquid, thus completing the melting process. During equipment operation, the cryogenic superconducting coil 50112 requires a continuous DC current supply to maintain its generated magnetic field strength, while also transmitting monitoring signals such as temperature and rotation speed. Since the cryogenic superconducting coil 50112 rotates at high speed, conventional wire connection methods cannot meet the power supply and signal transmission requirements. Therefore, a conductive slip ring 5012 is installed inside the superconducting melting shell 4. The conductive slip ring 5012 is located outside the melting crucible 5 and below the hollow motor element 5011. The conductive slip ring 5012 consists of a stator and a rotor. The rotor rotates synchronously with the rotating cryogenic superconducting coil 50112, while the stator is connected to a stationary external power supply and control system. The sliding of the conductive slip ring 5012... Contact conduction enables a stable DC power supply and bidirectional signal transmission for the cryogenic superconducting coil 50112 during continuous rotation, ensuring the reliability of the electrical connection of the cryogenic superconducting coil 50112 during rotational operation. Simultaneously, the cryogenic superconducting coil 50112 requires an extremely low temperature environment to maintain its superconducting state, and the superconducting magnet 6 also needs to be maintained in a superconducting state to ensure the generation of a stable static magnetic field. Therefore, a device frame 101 is fixedly connected to the top surface of the support base 1, and a magnet cooling module 1011 is fixedly connected inside the device frame 101. A helium gas pipe 10111 is installed at the top of the magnet cooling module 1011, and the magnet cooling module 1011 is supplied with external cooling medium through the helium gas pipe 10111. The system is connected, and the cooling medium enters the magnet cooling module 1011 through the helium gas connector 10111. After being distributed inside the magnet cooling module 1011, it is delivered to the cooling circuit containing the superconducting magnet 6 and the cryogenic superconducting coil 50112, continuously cooling the superconducting magnet 6 and the cryogenic superconducting coil 50112 to maintain them at the required low temperature, ensuring stable performance of their superconducting properties. Since the superconducting magnet 6 and the cryogenic superconducting coil 50112 need to be maintained at a low temperature, and the cryogenic superconducting coil 50112 is rotating at high speed, the cooling medium delivery channel needs to be reliably connected between the moving and stationary components. Simultaneously, it is necessary to prevent external heat from entering the cooling circuit and affecting the cooling effect. Therefore, a magnetic fluid seal 6011 is fixedly connected inside the superconducting melting shell 4. The magnetic fluid seal 6011 is used to seal the superconducting magnet 6. At the same time, a magnetic fluid fixing flange 601 is fixedly connected to one end of the superconducting magnet 6. The magnetic fluid fixing flange 601 and the magnetic fluid seal 6011 cooperate with each other. The magnetic fluid seal 6011 uses a liquid sealing ring formed by magnetic fluid under the action of magnetic field to form a sealing structure without solid contact between the rotating shaft and the stationary shell. This sealing structure allows the rotating part to rotate at high speed relative to the stationary part, and can effectively prevent the leakage of cooling medium and the intrusion of external gas, maintaining the vacuum insulation environment of the space where the superconducting magnet 6 and the low temperature superconducting coil 50112 are located, and ensuring the efficient operation of the cooling system. After the metal ingot 50113 is melted inside the melting crucible 5 to form molten metal, a discharge operation is required to remove the molten metal from the melting crucible 5. Two mounting supports 2 are fixedly connected to the inner side of the support base 1, symmetrically fixed on the front and rear sides of the top surface of the support base 1. Lifting cylinders 201 are hinged to the inner sides of both mounting supports 2. A connecting support plate 2011 is installed on the side of the lifting cylinder 201 facing away from the mounting support 2. The side of the connecting support plate 2011 facing away from the lifting cylinder 201 is connected to the standing platform 301. The bottom end of the standing platform 301 is fixedly connected to the rotating connecting seat 3 at the top of the support base 1, allowing the standing platform 301 to rotate relative to the support base 1 around the rotating connecting seat 3. When discharge is required, the system is activated. The lifting cylinder 201 is activated, and the piston rod of the lifting cylinder 201 begins to extend outward, in an upward output state. The extension action of the lifting cylinder 201 is transmitted to the standing platform 301 through the connecting support plate 2011. Since the standing platform 301 and the support base 1 are hinged together by the rotating connecting seat 3, the standing platform 301 begins to unfold outward around the rotating connecting seat 3 after being pushed by the lifting cylinder 201. The unfolding angle of the standing platform 301 gradually increases with the extension length of the lifting cylinder 201. During the unfolding process, the standing platform 301 synchronously drives the superconducting melting shell 4, which is fixedly connected to its inner side, to rotate together. The rotation axis of the superconducting melting shell 4 is consistent with the rotation axis of the standing platform 301, so that the superconducting melting shell 4 gradually changes from the initial vertical state to the inclined state. A connecting end seat 401 is fixedly connected to the top of the superconducting melting shell 4. The connecting end seat 401 extends upward through the standing platform 301. One end of the connecting end seat 401 is fixedly connected to a discharge guide seat 4011, which communicates with the connecting end seat 401. When the superconducting melting shell 4 tilts to a predetermined angle with the standing platform 301, the molten metal inside the melting crucible 5 flows downward along the inner wall of the melting crucible 5 under the action of gravity, flows into the interior of the connecting end seat 401, then flows into the interior of the discharge guide seat 4011, and finally flows out from the outlet of the discharge guide seat 4011, completing the discharge of the molten metal. After the operation and discharge are completed, the piston rod of the lifting cylinder 201 is retracted, which drives the standing platform 301 to retract inward around the rotating connecting seat 3. The superconducting melting shell 4 then returns to the vertical state, and the equipment enters the standby state, waiting for the next melting operation. In the entire melting and discharge process, multiple systems such as the hollow motor component 5011, the low temperature superconducting coil component 50112, the superconducting magnet 6, the conductive slip ring 5012, the magnet cooling module 1011, the magnetohydrodynamic seal 6011, and the lifting cylinder 201 work together to complete the complete process flow from loading the metal ingot 50113, heating and melting to discharging the molten metal.
