Description

Technical Field

[0001] This invention relates to the field of metal casting technology, and in particular to a continuous casting equipment for multiple metal alloys and its accessories. Background Technology

[0002] In the continuous casting process, high-temperature molten metal is fed into a copper tube, where it cools and forms a shell on its surface. The solidified shell contracts inward and detaches from the copper tube until it reaches equilibrium with the hydrostatic pressure of the molten metal. After the shell contracts inward, an air gap is created between the shell and the copper tube. The shell does not receive sufficient cooling and begins to reheat, while the hydrostatic pressure of the molten metal pulls the shell back onto the copper tube. The shell repeatedly expands and contracts within the copper tube until it detaches from the tube.

[0003] Heat transfer at the corners of the copper tube is two-dimensional, causing the molten metal at the corners to solidify and shrink earlier than the molten metal at the front of the tube. This asynchronous phase transformation shrinkage at the corners and in the rest of the tube makes the corners of the billet shell prone to cracking, resulting in a higher risk of leakage. Once molten metal leaks, it not only causes economic losses but also poses a significant safety hazard. Summary of the Invention

[0004] The purpose of this invention is to reduce the risk of corner cracking on the surface of molten metal.

[0009] Furthermore, the cross-sectional dimensions of the copper tube gradually decrease from top to bottom.

[0010] Furthermore, the continuous casting equipment for various metal alloys also includes: a connecting plate, located at the bottom end of the second rotating drum, fixedly connected to the second rotating drum, and supporting the sleeve; a lower flange, located at the bottom end of the sleeve, fixedly connected to the sleeve, and supporting the copper tube; a vibratory plate, ring-shaped, fixedly mounted on the mounting plate and located below the connecting plate; the vibratory plate and the through hole are coaxially arranged, and the opposite portions of the vibratory plate and the through hole are hollow; the upper surface of the vibratory plate undulates periodically in the circumferential direction; and a support foot, vertically arranged between the connecting plate and the vibratory plate; the top end of the support foot is connected to the connecting plate, and the bottom end abuts against the vibratory plate; the support foot is configured to rotate synchronously with the second rotating drum under the drive of the connecting plate and slide along the upper surface of the vibratory plate.

[0011] Furthermore, the undulation of the upper surface of the vibratory feeder gradually decreases from the inside to the outside; the support foot is configured to adjust its position relative to the vibratory feeder according to the rotation speed of the second drum during rotation; wherein, the higher the rotation speed of the second drum, the closer the support foot is to the outside of the vibratory feeder.

[0012] Furthermore, the bottom surface of the connecting plate is provided with an elongated groove arranged in the radial direction of the second rotating cylinder. A connecting rod is arranged horizontally in the length direction in the groove. The top of the support foot is slidably sleeved on the connecting rod. A compression spring is sleeved on the connecting rod.

[0015] The beneficial effects of this invention are:

[0016] This invention relates to a continuous casting equipment for various metal alloys. By incorporating heat dissipation fins on the outer wall of a copper tube, the heat dissipation efficiency of the tube's surface area is improved, the uniformity of overall heat dissipation efficiency is enhanced, and the risk of corner cracks in the molten metal surface is reduced. Simultaneously, the heat dissipation fins also increase the strength of the copper tube, reducing the risk of deformation. Furthermore, by setting the heat dissipation fins in an inclined position and setting the helix angle of the spirally flowing coolant within the annular chamber to the same angle as the fins' inclination, the resistance between the coolant and the fins is reduced. This allows for smoother coolant flow while maximizing heat removal from the fins, further improving the heat dissipation efficiency of the copper tube's surface area. This enhances the uniformity of overall heat dissipation efficiency and, consequently, reduces the risk of corner cracks in the molten metal surface. Attached Figure Description

[0036] The following reference Figures 1 to 13 This invention describes a continuous casting equipment for multiple metal alloys and its accessories.

[0037] This embodiment first provides a continuous casting equipment for multiple metal alloys. The continuous casting equipment for multiple metal alloys generally includes a mounting plate 100, a copper pipe 200, and a sleeve 300.

[0038] A through hole 110 is provided on the mounting plate 100. A copper tube 200 is vertically arranged above the mounting plate 100 and opposite to the through hole 110. The cross-section of the copper tube 200 is rectangular, and the cross-sectional dimension of the copper tube 200 is smaller than the dimension of the through hole 110. Multiple inclined heat dissipation fins 210 are provided on the outer surface of each sidewall of the copper tube 200, and the multiple heat dissipation fins 210 are spaced apart from top to bottom in the middle region of the sidewall of the copper tube 200. A sleeve 300 is coaxially fitted around the outer circumference of the copper tube 200. An annular chamber 310 is formed between the sleeve 300 and the copper tube 200, and the annular chamber 310 is filled with coolant flowing spirally from top to bottom; and the spiral angle of the coolant in the annular chamber 310 is consistent with the inclination angle of the heat dissipation fins 210.

[0039] The upper end of the annular chamber 310 is connected to an inlet pipe, and the lower end is connected to an outlet pipe. After entering the annular chamber 310, the coolant flows from top to bottom, cooling the copper tube 200. High-temperature molten metal continuously falls into the copper tube 200 from above, forming a shell within it and moving downwards before finally detaching from the tube. The through-hole 110 is opposite to the copper tube 200, and its size is larger than that of the copper tube 200 to allow the high-temperature molten metal detaching from the tube to pass smoothly through the through-hole 110 and continue falling for subsequent processing.

[0040] like Figure 5 As shown, in this embodiment, the copper pipe 200 has a square cross-section. The heat dissipation fins 210 are disposed in the middle of the side wall of the copper pipe 200, and the projected length of the heat dissipation fins 210 on the horizontal plane is less than the width of the side wall of the copper pipe 200.

[0041] In this embodiment, by providing heat dissipation fins 210 in the middle region of the sidewall of the copper tube 200, the heat dissipation efficiency in the middle region of the sidewall of the copper tube 200 is increased. This improves the uniformity of heat dissipation efficiency in the face and corner regions of the copper tube 200, resulting in a more uniform thickness of the shell formed on the surface of the molten metal. This, in turn, reduces the risk of cracking at the corners of the shell on the molten metal surface. The improved heat dissipation uniformity of the copper tube 200 prevents premature shrinkage of the shell corners, maintaining good contact between the shell and the copper tube 200, thereby improving heat conduction efficiency and further reducing the risk of shell cracking. Simultaneously, the provision of heat dissipation fins 210 strengthens the copper tube 200, thereby reducing the risk of deformation.

[0042] Furthermore, the heat dissipation fins 210 are configured to be inclined, and the spiral angle of the coolant flowing spirally within the annular chamber 310 is consistent with the inclination angle of the heat dissipation fins 210. This reduces the resistance between the heat dissipation fins 210 and the coolant, making the coolant flow smoother and maximizing the removal of heat from the heat dissipation fins 210. This further improves the heat dissipation efficiency of the surface area of ​​the copper pipe 200, thereby improving the uniformity of the overall heat dissipation efficiency of the copper pipe 200 and reducing the risk of cracking at the corners of the blank on the surface of the molten metal.

[0043] In some preferred embodiments, the ends of the heat dissipation fins 210 are arc-shaped to reduce the flow resistance of the coolant. Water is preferably used as the coolant, as it is readily available and inexpensive.

[0044] Continuous casting equipment for multiple metal alloys may also generally include a first rotary drum 400.

[0045] The first rotating drum 400 is coaxially sleeved between the sleeve 300 and the copper tube 200. Multiple vertical push plates 410 are arranged circumferentially on the inner wall of the first rotating drum 400 to drive the coolant in the annular chamber 310 to rotate.

[0046] In this embodiment, a rotatable first rotating drum 400 is provided in the annular chamber 310, and a pusher plate 410 is provided on the first rotating drum 400. The rotation of the first rotating drum 400 drives the pusher plate 410 to move, thereby promoting the spiral flow of coolant.

[0047] In some preferred embodiments, multiple push plates 410 are evenly distributed around the first rotating cylinder 400, so that the coolant in the annular chamber 310 flows more evenly and stably under the push of the push plates 410.

[0048] Continuous casting equipment for various metal alloys may also generally include a second rotary drum 500 and a motor 600.

[0049] The second rotating drum 500 is coaxially sleeved on the outer circumference of the sleeve 300. The motor 600 is mounted on the mounting plate 100 and connected to the second rotating drum 500 to drive the second rotating drum 500 to rotate. A plurality of first magnets 420 are arranged circumferentially at intervals on the outer wall surface of the first rotating drum 400, and a plurality of second magnets 510 are correspondingly arranged on the inner wall surface of the second rotating drum 500; the first magnets 420 and the second magnets 510 attract each other.

[0050] In this embodiment, a second rotating cylinder 500 is fitted on the outside of the sleeve 300, and a first magnet 420 and a second magnet 510 that attract each other are respectively provided on the first rotating cylinder 400 and the second rotating cylinder 500. By utilizing the magnetic attraction, the first rotating cylinder 400 can rotate under the drive of the second rotating cylinder 500 without affecting the sealing effect of the annular cavity 310.

[0051] In some preferred embodiments, the first magnet 420 and the second magnet 510 are evenly distributed on the first rotating cylinder 400 and the second rotating cylinder 500, respectively, making the magnetic force distribution more uniform and thus making the rotation of the second rotating cylinder 500 more stable. The first magnet 420 and the second magnet 510 are vertically arranged, and the first magnet 420 and the second magnet 510 are fully distributed from top to bottom on the cylinder bodies of the first rotating cylinder 400 and the second rotating cylinder 500, respectively, making the magnetic force between the first rotating cylinder 400 and the second rotating cylinder 500 greater, thereby ensuring that the rotation of the first rotating cylinder 400 is more stable.

[0052] Continuous casting equipment for various metal alloys may also generally include a third rotary drum 700 and a drive wheel 750.

[0053] The third rotating drum 700 is sleeved on the outer periphery of the second rotating drum 500 and is used to drive the second rotating drum 500 to rotate; the top surface of the third rotating drum 700 is provided with a first bevel tooth 710. The transmission wheel 750 is fixedly connected to the drive shaft 610 of the motor 600, and the side wall of the transmission wheel 750 is provided with a second bevel tooth 751 that meshes with the first bevel tooth 710.

[0054] like Figure 1-2 As shown, the motor 600 is horizontally mounted on the mounting plate 100. The drive shaft 610 of the motor 600 is fixedly connected to the transmission wheel 750. The second bevel tooth 751 on the transmission wheel 750 meshes with the first bevel tooth 710 of the third rotating drum 700, thereby transmitting the power of the motor 600 to the third rotating drum 700 and driving the third rotating drum 700 to rotate.

[0055] like Figure 3As shown, in some embodiments, a plurality of locking blocks 530 are uniformly arranged on the outer wall of the second rotating drum 500, and a plurality of locking slots 720 are correspondingly arranged on the inner wall of the third rotating drum 700. The locking blocks 530 are accommodated in the locking slots 720 and are used to transmit torque when the third rotating drum 700 rotates, thereby driving the second rotating drum 500 to rotate. The locking blocks 530, the second rotating drum 500, and the second magnet 510 can be integrally formed.

[0056] In other embodiments, the second rotating drum 500 and the third rotating drum 700 may each be provided with a keyway opposite to each other, and a key is provided between the two keyways. The second rotating drum 500 and the third rotating drum 700 are connected by the key to achieve synchronous rotation.

[0057] The cross-sectional dimensions of the copper tube 200 gradually decrease from top to bottom.

[0058] During continuous casting, the high-temperature molten metal gradually cools and solidifies inside the copper tube 200. After the molten metal solidifies, an air gap is formed between it and the copper tube 200, which leads to increased thermal resistance and reduced heat transfer efficiency.

[0059] In this embodiment, the cross-sectional dimensions of the copper tube 200 are set to gradually decrease from top to bottom, thereby compensating for the solidification shrinkage of the metal. This allows the molten metal to maintain close contact with the copper tube 200, reducing the formation of air gaps, thereby improving heat transfer efficiency, promoting rapid solidification of the molten metal, and reducing the risk of defects such as shrinkage cavities and porosity.

[0060] Continuous casting equipment for various metal alloys may also generally include a connecting plate 520, a lower flange 340, a vibratory plate 130, and a support foot 800.

[0061] A connecting plate 520 is located at the bottom end of the second rotating drum 500, fixedly connected to the second rotating drum 500, and supports the sleeve 300. A lower flange 340 is located at the bottom end of the sleeve 300, fixedly connected to the sleeve 300, and supports the copper tube 200. The vibratory plate 130 is annular, fixedly mounted on the mounting plate 100, and located below the connecting plate 520. The vibratory plate 130 and the through hole 110 are coaxially arranged, and the opposite portions of the vibratory plate 130 and the through hole 110 are hollow. The upper surface of the vibratory plate 130 undulates periodically in the circumferential direction. A support foot 800 is vertically arranged between the connecting plate 520 and the vibratory plate 130. The top end of the support foot 800 is connected to the connecting plate 520, and the bottom end abuts against the vibratory plate 130. The support foot 800 is configured to rotate synchronously with the second rotating drum 500 under the drive of the connecting plate 520, and slide along the upper surface of the vibratory plate 130.

[0062] like Figure 3As shown, the connecting plate 520 has an annular stepped surface on the side near the sleeve 300, and an annular first support plate 320 is formed on the bottom end of the sleeve 300 facing the second rotating cylinder 500. The bottom part of the first support plate 320 abuts against the annular stepped surface. A bearing 540 is also placed above the connecting plate 520. The outer side of the bearing 540 abuts against the second rotating cylinder 500, and the inner side abuts against the first support plate 320, making the rotation of the second rotating cylinder 500 relative to the sleeve 300 smoother. The lower flange 340 is located below the first support plate 320, is fixedly connected to the first support plate 320 by bolts, and supports the copper pipe 200. A sealing gasket 390 is provided between the lower flange 340 and the first support plate 320.

[0063] A second annular support plate 330 is formed on the top of the sleeve 300 facing the second rotating cylinder 500, and an upper flange 350 is provided above the second support plate 330. The upper flange 350 and the second support plate 330 are fixedly connected by bolts. A rectangular stepped surface is formed on the side of the upper flange 350 facing the copper pipe 200, and the upper end face of the copper pipe 200 and the side wall facing the sleeve 300 abut against the stepped surface of the upper flange 350. A gasket 370 and a sealing ring 380 are also arranged sequentially between the upper flange 350 and the first rotating cylinder 400. One side of the gasket 370 and the sealing ring 380 abuts against the sleeve 300, and the other side abuts against the copper pipe 200. Corresponding stepped surfaces are formed in the areas of the sleeve 300 opposite to the gasket 370 and the sealing ring 380, and corresponding grooves are formed in the areas of the copper pipe 200 opposite to the sealing ring 380, so that the sealing effect of the gasket 370 and the sealing ring 380 is better.

[0064] Multiple liquid inlets 351 are evenly arranged on the upper flange 350. Each liquid inlet 351 is connected to a liquid inlet pipe via a pipe joint 360, and the liquid inlet pipe is connected to a pump body. The pump body is used to deliver coolant into the annular chamber 310 and regulate the coolant flow rate. Multiple liquid outlets 341 are evenly arranged on the lower flange 340. Each liquid outlet 341 is connected to a liquid outlet pipe via a pipe joint 360. The continuous casting equipment for various metal alloys may also include a control device for regulating the pump body according to the rotational speed of the first drum 400, so that the coolant flow rate matches the rotational speed of the first drum 400, thereby ensuring that the spiral angle of the coolant during spiral flow in the annular chamber 310 and the tilt angle of the heat dissipation fins 210 remain consistent.

[0065] In this embodiment, a support foot 800 is provided between the connecting plate 520 and the vibrating plate 130. The upper end of the support foot 800 is connected to the connecting plate 520, and the lower end abuts against the vibrating plate 130. When the support foot 800 rotates synchronously with the second rotating drum 500, it slides on the upper surface of the vibrating plate 130, thereby causing the support foot 800 to push the connecting plate 520 to move up and down. When the connecting plate 520 moves up and down, it pushes the second rotating drum 500 and the sleeve 300 to vibrate up and down. When the sleeve 300 vibrates up and down, it drives the lower flange 340 to move up and down, thereby pushing the first rotating drum 400 and the copper pipe 200 to vibrate up and down, thus promoting the flow of molten metal in the copper pipe 200 and eliminating air bubbles and pores in the molten metal.

[0066] like Figure 3 As shown, the locking block 530 on the second rotating drum 500 is vertically arranged, and the locking groove 720 on the third rotating drum 700 is a vertically arranged through groove. While the locking block 530 and the locking groove 720 cooperate to transmit torque, the locking block 530 can move up and down relative to the locking groove 720. The outer portions of the bevel teeth of the third rotating drum 700 and the second rotating drum 500 mesh, providing clearance for the movement of the locking block 530. Multiple connecting holes are evenly arranged circumferentially in the area of ​​the connecting plate 520 opposite to the third rotating drum 700. Multiple connecting posts 730 are fixedly arranged below the third rotating drum 700, extending into the connecting holes and moving up and down along the connecting holes. A support spring 740 is sleeved on the connecting post 730, with one end of the support spring 740 abutting against the lower surface of the third rotating drum 700 and the other end abutting against the upper surface of the connecting plate 520. When the support foot 800 slides along the raised portion of the vibratory plate 130, it pushes the connecting plate 520 and the second rotating drum 500 upwards. The connecting plate 520 presses against the support spring 740, compressing the support spring 740. When the support foot 800 slides along the recessed portion of the vibratory plate 130, the connecting plate 520 and the second rotating drum 500 move downwards under the action of gravity, and the support spring 740 extends. Even when the support foot 800 is at the lowest point of the upper surface of the vibratory plate 130, the support spring 740 still has a certain amount of pre-compression to ensure that the third rotating drum 700, supported by the support spring 740, can always maintain good meshing with the transmission wheel 750, thereby ensuring effective power transmission.

[0067] like Figure 1 As shown, multiple limiting posts 120 are evenly arranged around the periphery of the third rotating drum 700. The bottom end of the limiting post 120 is fixed to the mounting plate 100, and the top end passes through the upper flange 350. The upper flange 350 can move up and down along the limiting posts 120. The multiple limiting posts 120 guide the movement direction of the upper flange 350, making the movement of the upper flange 350 more stable.

[0068] In some embodiments, a plurality of support feet 800 evenly distributed circumferentially may be provided below the connecting plate 520. The plurality of support feet 800 slide synchronously on the upper surface of the vibrating plate 130 and jointly push the connecting plate 520 to move up and down, so as to further improve the vibration stability of the copper tube 200.

[0069] like Figure 1-2 As shown in this embodiment, two symmetrical support feet 800 can be provided below the connecting plate 520, and the vibrating plate 130 is symmetrical about its center. The two support feet 800 slide synchronously against the upper surface of the vibrating plate 130, jointly pushing the connecting plate 520 to move up and down, making the vibration of the copper tube 200 more stable.

[0070] The degree of undulation on the upper surface of the vibratory feeder 130 gradually decreases from the inside to the outside. The support foot 800 is configured to adjust its position relative to the vibratory feeder 130 according to the rotation speed of the second rotating drum 500 during rotation, wherein the higher the rotation speed of the second rotating drum 500, the closer the support foot 800 is to the outside of the vibratory feeder 130.

[0071] When the speed of motor 600 increases, it drives the speed of the second rotating drum 500 and the first rotating drum 400 to increase, which increases the cooling efficiency of the coolant in the annular chamber 310. At the same time, it increases the vibration frequency of components such as the second rotating drum 500 and copper tube 200, making the copper tube 200 suitable for high-speed continuous casting.

[0072] In this embodiment, the undulation of the vibratory feeder 130 is set to gradually decrease from the inside to the outside. The support foot 800 is configured to adjust its position relative to the vibratory feeder 130 according to the rotational speed of the second drum 500. This ensures that the higher the rotational speed of the second drum 500 (i.e., the higher its vibration frequency), the closer the support foot 800 is to the outside of the vibratory feeder 130, thus reducing the amplitude of the second drum 500. Matching the amplitude and vibration frequency of the second drum 500 improves the operational stability of the equipment, ensures its service life, reduces the risk of structural damage, and lowers safety hazards.

[0073] The bottom surface of the connecting plate 520 is provided with an elongated groove 521 arranged radially along the second rotating cylinder 500. A connecting rod 522 is arranged horizontally along the length direction in the groove 521. The top end of the support foot 800 is slidably sleeved on the connecting rod 522. A compression spring 523 is sleeved on the connecting rod 522. One end of the compression spring 523 abuts against the groove wall near the outer side of the groove 521, and the other end abuts against the support foot 800.

[0074] In this embodiment, a connecting rod 522 is provided in the groove 521 at the bottom of the connecting plate 520. The top end of the support foot 800 is sleeved on the connecting rod 522, and a compression spring 523 is sleeved on the connecting rod 522. When the support foot 800 slides on the vibrating plate 130, it can move along the connecting rod 522 under the action of centrifugal force and the pressure of the compression spring 523, so that the amplitude and vibration frequency of the copper tube 200 are matched. This not only has a simple and exquisite structure, but also operates stably.

[0075] The higher the speed of motor 600, the higher the speed of the second rotating drum 500, which in turn drives the sliding speed of the support foot 800, resulting in a higher vibration frequency of the copper tube 200. At this time, the centrifugal force on the support foot 800 is also greater, causing it to move a greater distance along the connecting rod 522. This brings the support foot 800 closer to the periphery of the vibrating plate 130, thus reducing the amplitude of the copper tube 200. The matching of the amplitude and vibration frequency of the copper tube 200 improves the operational stability of the equipment.

[0076] The base of the support foot is hemispherical.

[0077] In this embodiment, the bottom of the support foot 800 is set to a hemispherical shape, thereby reducing the sliding resistance between the support foot 800 and the vibrating plate 130, making the sliding of the support foot 800 smoother and more stable.

[0078] In other embodiments, the bottom end of the support foot 800 may be provided with ball bearings to reduce the sliding resistance between the support foot 800 and the vibratory plate 130.

[0079] This embodiment also provides an accessory for a continuous casting equipment for multiple metal alloys, applicable to any of the above-mentioned continuous casting equipment for multiple metal alloys, including multiple spray pipes 900.

[0080] Multiple spray pipes 900 are installed at the bottom of the mounting plate 100 of the continuous casting equipment for various metal alloys, and are evenly distributed around the through holes 110 on the mounting plate 100. Each spray pipe 900 has multiple evenly distributed nozzles 910 on the wall facing the through hole 110.

[0081] In this embodiment, a spray pipe 900 is installed at the bottom of the mounting plate 100 to perform secondary cooling on the molten metal with a billet shell that has been extracted from the copper pipe 200. This promotes the thickening of the billet shell, increases its strength, and facilitates subsequent processes. Multiple spray pipes 900 are evenly arranged around the through hole 110, and each spray pipe 900 is equipped with multiple evenly distributed nozzles 910. This ensures a uniform distribution of cooling intensity during secondary cooling, preventing stress concentration caused by localized overheating or undercooling of the billet shell and reducing the risk of cracking.

[0082] The specific working process of the continuous casting equipment for various metal alloys provided by the present invention will be described in conjunction with the above embodiments:

[0083] High-temperature molten metal flows into copper tube 200 from above, then flows downwards within the tube, forming a shell on its surface under the cooling effect of the tube's sidewalls. After the molten metal shell detaches from the tube 200, it passes through through hole 110 and falls into the spray pipes, where it undergoes secondary cooling under the action of coolant sprayed from nozzle 910, further thickening the shell.

[0084] As the high-temperature molten metal flows through the copper pipe 200, the motor 600 starts, driving the transmission wheel 750 to rotate. The transmission wheel 750, through the meshing of bevel teeth, drives the third rotating drum 700 to rotate. The rotation of the third rotating drum 700, through the engagement of the locking block 530 and the locking slot 720, drives the second rotating drum 500 to rotate. The rotation of the second rotating drum 500, through the magnetic attraction between the first magnet 420 and the second magnet 510, drives the first rotating drum 400 to rotate. The rotation of the first rotating drum 400 drives the push plate 410 to rotate, thereby pushing the coolant in the annular chamber 310 to spiral downwards.

[0085] The rotation of the second rotating drum 500 simultaneously drives the connecting plate 520 and the support foot 800 to rotate. As the support foot 800 rotates with the second rotating drum 500, its bottom end slides along the upper surface of the vibrating plate 130, thereby pushing the connecting plate 520 to move up and down. The up-and-down movement of the connecting plate 520 drives the second rotating drum 500, the first rotating drum 400, the sleeve 300, and the copper tube 200 to move up and down synchronously. As the support foot 800 rotates with the second rotating drum 500, it also moves along the connecting rod 522 under the action of centrifugal force. The higher the rotational speed of the second rotating drum 500, the higher the vibration frequency of the copper tube 200, and the closer the support foot 800 is to the outer periphery of the vibrating plate 130 under the action of centrifugal force, resulting in a smaller amplitude of the copper tube 200.

[0086] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0087] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
