Description

Technical Field

[0001] The present invention relates to the technical field of metal casting, in particular to a continuous casting device for multiple metal alloys and accessories thereof. Background Art

[0002] During the continuous casting process, hot molten metal is fed into a copper tube. As the tube cools, a shell forms on its surface. The solidified shell contracts inward, separating from the tube until it reaches equilibrium with the static pressure of the molten metal. This contraction creates an air gap between the shell and the tube, preventing the shell from adequately cooling and causing it to reheat. The static pressure of the molten metal then pushes the shell against the tube. The shell repeatedly expands and contracts within the tube until it releases.

[0003] Heat transfer at the corners of copper tubes is two-dimensional, causing the molten metal there to solidify and shrink earlier than the molten metal at the tube's surface. The phase change and shrinkage of the molten metal at the corners is out of sync with that of the molten metal in the remaining areas, making cracks more likely to form at the corners of the shell, leading to a higher risk of leakage. Once molten metal leaks, it not only causes economic losses but also poses safety risks. Summary of the Invention

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

When a feature "includes or contains" one or more of the features it covers, unless otherwise specifically described, this indicates that other features are not excluded and may further include other features.

[0020] Unless otherwise expressly specified or limited, the terms "mounted," "connected," "connect," "fixed," "coupled," and the like should be interpreted broadly. For example, they may refer to fixed or detachable connections, or integration; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components or interaction between two components, unless otherwise expressly limited. A person of ordinary skill in the art should be able to understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0021] Refer to the following Figures 1 to 13 The present invention will be used to describe a continuous casting device for various metal alloys and its accessories.

[0022] This embodiment first provides a continuous casting device for various metal alloys. The continuous casting device for various metal alloys generally includes a mounting plate 100 , a copper tube 200 , and a sleeve 300 .

[0023] A through hole 110 is provided on the mounting plate 100. The 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 size of the copper tube 200 is smaller than the size of the through hole 110. A plurality of inclined heat dissipation fins 210 are provided on the outer surface of each side wall of the copper tube 200, and the plurality of heat dissipation fins 210 are arranged at intervals from top to bottom in the middle area of ​​the side wall of the copper tube 200. The sleeve 300 is coaxially sleeved on 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 in a spiral from top to bottom; and the spiral rise angle of the coolant in the annular chamber 310 is consistent with the inclination angle of the heat dissipation fins 210.

[0024] The upper end of the annular chamber 310 is connected to a liquid inlet pipeline, and the lower end of the annular chamber 310 is connected to a liquid outlet pipeline. After entering the annular chamber 310, the coolant flows from top to bottom, cooling the copper tube 200. The hot molten metal continuously falls into the copper tube 200 from above, then forms a shell inside the copper tube 200 and moves downward, finally separating from the copper tube 200. The through hole 110 is opposite to the copper tube 200 and is larger than the copper tube 200. This allows the hot molten metal that has separated from the copper tube 200 to pass smoothly through the through hole 110 and continue to fall, facilitating subsequent processing.

[0025] like Figure 5 As shown, in the embodiment, the cross section of the copper tube 200 is square. The heat dissipation fins 210 are arranged in the middle of the side wall of the copper tube 200 , and the projected length of the heat dissipation fins 210 on the horizontal plane is smaller than the width of the side wall of the copper tube 200 .

[0026] The solution of this embodiment increases the heat dissipation efficiency of the middle area of ​​the sidewall of the copper tube 200 by providing heat dissipation fins 210. This improves the uniformity of heat dissipation efficiency in the face and corner areas of the copper tube 200, making the thickness of the shell formed on the surface of the molten metal more uniform, thereby reducing the risk of cracking at the corners of the shell on the surface of the molten metal. This improved heat dissipation uniformity of the copper tube 200 prevents premature shrinkage of the shell corners, maintains good contact between the shell and the copper tube 200, improves heat conduction efficiency, and further reduces the risk of shell cracking. Furthermore, the provision of heat dissipation fins 210 strengthens the strength of the copper tube 200, thereby reducing the risk of deformation of the copper tube 200.

[0027] In addition, the heat sink fins 210 are configured to be inclined, and the spiral rise angle of the coolant flowing in the annular chamber 310 is consistent with the inclination angle of the heat sink fins 210, so that the resistance between the heat sink fins 210 and the coolant is reduced, which not only makes the flow of the coolant smoother, but also can take away the heat on the heat sink fins 210 to the greatest extent, further improving the heat dissipation efficiency of the facial area of ​​the copper tube 200, thereby improving the uniformity of the overall heat dissipation efficiency of the copper tube 200, and further reducing the risk of cracking at the corners of the shell on the surface of the molten metal.

[0028] In some preferred embodiments, both ends of the heat dissipation fins 210 are curved to reduce the flow resistance of the cooling liquid. The cooling liquid is preferably water, which is not only easy to obtain but also low in cost.

[0029] The continuous casting apparatus for various metal alloys may generally further include a first rotating drum 400 .

[0030] The first rotating drum 400 is coaxially sleeved between the sleeve 300 and the copper tube 200. A plurality of vertical push plates 410 are arranged on the inner wall surface of the first rotating drum 400 at intervals along the circumferential direction, for driving the coolant in the annular chamber 310 to rotate.

[0031] In the solution of this embodiment, a rotatable first drum 400 is provided in the annular chamber 310 , and a push plate 410 is provided on the first drum 400 , so that the rotation of the first drum 400 drives the push plate 410 to move, thereby promoting the spiral flow of the coolant.

[0032] In some preferred embodiments, the plurality of push plates 410 are evenly distributed in the circumferential direction of the first drum 400 , so that the coolant in the annular chamber 310 flows more evenly and stably under the push of the push plates 410 .

[0033] The continuous casting apparatus for various metal alloys may generally further include a second rotating drum 500 and a motor 600 .

[0034] The second rotating drum 500 is coaxially mounted on the outer periphery of the sleeve 300. A motor 600 is mounted on the mounting plate 100 and connected to the second rotating drum 500, driving the second rotating drum 500 to rotate. A plurality of first magnets 420 are circumferentially spaced apart on the outer wall of the first rotating drum 400, while a plurality of second magnets 510 are correspondingly mounted on the inner wall of the second rotating drum 500; the first magnets 420 and second magnets 510 attract each other.

[0035] The solution of this embodiment is to arrange a second rotating drum 500 on the outer side of the sleeve 300, and respectively provide a first magnet 420 and a second magnet 510 that attract each other on the first rotating drum 400 and the second rotating drum 500, so as to utilize the magnetic attraction effect to enable the first rotating drum 400 to rotate under the drive of the second rotating drum 500 without affecting the sealing effect of the annular chamber 310.

[0036] In some preferred embodiments, the first magnets 420 and the second magnets 510 are evenly distributed on the first and second rotating drums 400, 500, respectively, to achieve a more uniform magnetic force distribution, thereby ensuring more stable rotation of the second rotating drum 500. The first magnets 420 and the second magnets 510 are arranged vertically, and the first magnets 420 and the second magnets 510 are distributed from top to bottom throughout the first and second rotating drums 400, 500, respectively, to increase the magnetic force between the first and second rotating drums 400, 500, thereby ensuring more stable rotation of the first rotating drum 400.

[0037] The continuous casting apparatus for various metal alloys may generally further include a third rotating drum 700 and a transmission wheel 750 .

[0038] The third rotating drum 700 is sleeved around 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 first bevel gears 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 second bevel gears 751 that mesh with the first bevel gears 710.

[0039] like Figure 1-2 As shown, the motor 600 is horizontally arranged on the mounting plate 100, the driving shaft 610 of the motor 600 is fixedly connected to the transmission wheel 750, and the second bevel gear 751 on the transmission wheel 750 is engaged with the first bevel gear 710 of the third rotating drum 700, thereby transmitting the power of the motor 600 to the third rotating drum 700, driving the rotation of the third rotating drum 700.

[0040] like Figure 3As shown, in some embodiments, a plurality of clamping blocks 530 are evenly disposed on the outer wall of the second rotating drum 500, and a plurality of clamping grooves 720 are correspondingly disposed on the inner wall of the third rotating drum 700. The clamping blocks 530 are received in the clamping grooves 720 and are used to transmit torque when the third rotating drum 700 rotates, thereby driving the second rotating drum 500 to rotate. The clamping blocks 530, the second rotating drum 500, and the second magnet 510 can be integrally formed.

[0041] In other embodiments, the second drum 500 and the third drum 700 may each be provided with a keyway facing each other, with a key being provided between the two keyways. The second drum 500 and the third drum 700 are connected by the key to achieve synchronous rotation.

[0042] The cross-sectional dimensions of the copper tube 200 gradually decrease from top to bottom.

[0043] During the continuous casting process, the high-temperature molten metal gradually cools and solidifies in the copper tube 200. After the molten metal solidifies, an air gap is formed between the molten metal and the copper tube 200, resulting in increased thermal resistance and reduced heat transfer efficiency.

[0044] In the solution of 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, allowing 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 shrinkage.

[0045] The continuous casting equipment for various metal alloys may generally further include a connecting plate 520 , a lower flange 340 , a vibration plate 130 , and a support foot 800 .

[0046] The connecting plate 520 is disposed at the bottom end of the second rotating drum 500, fixedly connected to the second rotating drum 500, and supports the sleeve 300. The lower flange 340 is disposed at the bottom end of the sleeve 300, fixedly connected to the sleeve 300, and supports the copper tube 200. The vibrating disk 130 is annular and fixedly mounted on the mounting plate 100, located below the connecting plate 520. The vibrating disk 130 and the through hole 110 are coaxially arranged, and the portion facing the vibrating disk 130 is hollow. The upper surface of the vibrating disk 130 periodically undulates along the circumferential direction. The support foot 800 is vertically disposed between the connecting plate 520 and the vibrating disk 130. The top end of the support foot 800 is connected to the connecting plate 520, and the bottom end abuts the vibrating disk 130. The support foot 800 is configured to rotate synchronously with the second rotating drum 500, driven by the connecting plate 520, and to slide along the upper surface of the vibrating disk 130.

[0047] like Figure 3As shown, an annular stepped surface is formed on the side of the connecting plate 520 that is closest to the sleeve 300. An annular first support plate 320 is formed on the bottom end of the sleeve 300 that faces the second rotating drum 500. The bottom surface of the first support plate 320 partially abuts the annular stepped surface. A bearing 540 is also positioned above the connecting plate 520. The outer side of the bearing 540 abuts the second rotating drum 500, while the inner side abuts the first support plate 320, ensuring smoother rotation of the second rotating drum 500 relative to the sleeve 300. A lower flange 340 is disposed below the first support plate 320 and is fixedly connected to the first support plate 320 by bolts. It also supports the copper tube 200. A sealing gasket 390 is disposed between the lower flange 340 and the first support plate 320.

[0048] An annular second support plate 330 is formed on the top of the sleeve 300, facing the second rotating drum 500. An upper flange 350 is positioned 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 tube 200. The upper end surface and the sidewall of the copper tube 200 facing the sleeve 300 abut against the stepped surface of the upper flange 350. A gasket 370 and a sealing ring 380 are positioned between the upper flange 350 and the first rotating drum 400, respectively. One side of each gasket 370 and sealing ring 380 abuts the sleeve 300, while the other side abuts the copper tube 200. Corresponding stepped surfaces are formed in the areas of the sleeve 300 facing the gasket 370 and sealing ring 380, while corresponding grooves are formed in the area of ​​the copper tube 200 facing the sealing ring 380, enhancing the sealing effect of the gasket 370 and sealing ring 380.

[0049] A plurality of liquid inlets 351 are evenly arranged on the upper flange 350, and the liquid inlets 351 are connected to a liquid inlet pipeline via a pipe joint 360, and the liquid inlet pipeline is connected to a pump body. The pump body is used to transport coolant into the annular chamber 310 and regulate the flow rate of the coolant. A plurality of liquid outlets 341 are evenly arranged on the lower flange 340, and the liquid outlets 341 are connected to a liquid outlet pipeline via a pipe joint 360. The continuous casting equipment for multiple metal alloys may also include a control device for regulating the pump body according to the rotational speed of the first rotating drum 400, so that the flow rate of the coolant matches the rotational speed of the first rotating drum 400, thereby maintaining the spiral rise angle of the coolant in the annular chamber 310 and the inclination angle of the heat sink fins 210.

[0050] The solution of this embodiment is to dispose a support foot 800 between the connecting plate 520 and the vibration disk 130, so that the upper end of the support foot 800 is connected to the connecting plate 520 and the lower end is in contact with the vibration disk 130. When the support foot 800 rotates synchronously with the second rotating drum 500, the support foot 800 slides on the upper surface of the vibration disk 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 tube 200 to vibrate up and down, thereby promoting the flow of molten metal in the copper tube 200 and eliminating bubbles and pores in the molten metal.

[0051] like Figure 3 As shown, the clamping block 530 on the second rotating drum 500 is vertically arranged, while the clamping slot 720 on the third rotating drum 700 is a vertical through-slot. The clamping block 530 and the clamping slot 720 cooperate to transmit torque, allowing the clamping block 530 to move up and down relative to the clamping slot 720. The outer portions of the bevel teeth on the third rotating drum 700 and the second rotating drum 500 mesh, providing clearance for the clamping block 530 to move. The area of ​​the connecting plate 520 facing the third rotating drum 700 is uniformly circumferentially arranged with multiple connecting holes. A plurality of connecting posts 730 are fixedly mounted below the third rotating drum 700. These connective posts 730 extend into the connective holes and are movable up and down along the holes. A support spring 740 is sleeved over the connective posts 730, one end of which abuts the bottom surface of the third rotating drum 700 and the other end abuts the top surface of the connecting plate 520. When the support foot 800 slides along the raised portion of the vibration disk 130, it pushes the connecting plate 520 and the second rotating drum 500 upward, and the connecting plate 520 presses against the support spring 740, causing the support spring 740 to be compressed. When the support foot 800 slides along the recessed portion of the vibration disk 130, the connecting plate 520 and the second rotating drum 500 move downward under the action of gravity, and the support spring 740 extends. Specifically, when the support foot 800 is at the lowest point on the upper surface of the vibration disk 130, the support spring 740 still has a certain amount of pre-compression, ensuring that the third rotating drum 700, supported by the support spring 740, can always be in a good meshing state with the transmission wheel 750, thereby ensuring the power transmission effect.

[0052] like Figure 1 As shown, multiple limiting posts 120 are evenly distributed around the periphery of the third rotating drum 700. The bottom ends of the limiting posts 120 are fixed to the mounting plate 100, and the top ends pass 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 of the upper flange 350, making the movement of the upper flange 350 more stable.

[0053] In some embodiments, a plurality of support feet 800 evenly distributed along the circumference may be provided below the connecting plate 520. The plurality of support feet 800 slide synchronously on the upper surface of the vibration disk 130 to jointly push the connecting plate 520 up and down to further improve the vibration stability of the copper tube 200.

[0054] like Figure 1-2 As shown, in this embodiment, two symmetrical support feet 800 can be provided below the connecting plate 520, and the vibration plate 130 is symmetrical about its center. The two support feet 800 abut against the upper surface of the vibration plate 130 and slide synchronously, jointly pushing the connecting plate 520 up and down, making the vibration of the copper tube 200 more stable.

[0055] The undulation of the upper surface of the vibration plate 130 gradually decreases from the inner side to the outer side. The support foot 800 is configured to adjust its position relative to the vibration plate 130 according to the rotation speed of the second rotating drum 500 during rotation. The higher the rotation speed of the second rotating drum 500, the closer the support foot 800 is to the outer side of the vibration plate 130.

[0056] When the speed of the motor 600 increases, the speed of the second rotating drum 500 and the first rotating drum 400 also increases, thereby increasing the cooling efficiency of the coolant in the annular chamber 310 and increasing the vibration frequency of components such as the second rotating drum 500 and the copper tube 200, so that the copper tube 200 can be suitable for high-speed continuous casting.

[0057] In this embodiment, the vibration plate 130's undulation is configured to gradually decrease from the inside outward, and the support legs 800 are configured to adjust their position relative to the vibration plate 130 based on the rotational speed of the second rotating drum 500. This results in a higher rotational speed (i.e., a higher vibration frequency) for the second rotating drum 500, and a lower amplitude for the second rotating drum 500. This matching of the vibration amplitude and frequency of the second rotating drum 500 improves the operational stability of the equipment, ensures its service life, reduces the risk of structural damage, and mitigates safety hazards.

[0058] The bottom surface of the connecting plate 520 is provided with an elongated groove 521 extending radially along the second drum 500. A connecting rod 522 is disposed in the groove 521, extending horizontally along the length thereof. The top end of the support foot 800 is slidably mounted on the connecting rod 522. A compression spring 523 is mounted on the connecting rod 522. One end of the compression spring 523 abuts the outer wall of the groove 521, and the other end abuts the support foot 800.

[0059] The solution of this embodiment is to set a connecting rod 522 in the groove 521 at the bottom of the connecting plate 520, sleeve the top end of the supporting foot 800 on the connecting rod 522, and sleeve a compression spring 523 on the connecting rod 522, so that when the supporting foot 800 slides on the vibration disk 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. It is not only simple and sophisticated in structure, but also stable in operation.

[0060] When the motor 600 rotates at a higher speed, the second drum 500 rotates at a higher speed, driving the support foot 800 to slide at a higher speed, resulting in a higher vibration frequency for the copper tube 200. At this point, the centrifugal force on the support foot 800 increases, and the distance the support foot 800 moves along the connecting rod 522 increases, bringing the support foot 800 closer to the periphery of the vibrating plate 130, thereby reducing the vibration amplitude of the copper tube 200. This ensures that the vibration amplitude and vibration frequency of the copper tube 200 match, thereby improving the operational stability of the device.

[0061] The bottom end of the support foot 800 is hemispherical.

[0062] In the solution of this embodiment, the bottom end of the support foot 800 is set to be hemispherical, thereby reducing the sliding resistance between the support foot 800 and the vibration plate 130, making the sliding of the support foot 800 smoother and more stable.

[0063] In other embodiments, a ball bearing may be provided at the bottom end of the support foot 800 to reduce the sliding resistance between the support foot 800 and the vibration plate 130 .

[0064] This embodiment also provides an accessory for a continuous casting device for multiple metal alloys, which is applicable to any of the above-mentioned continuous casting devices for multiple metal alloys and includes multiple spray pipes 900 .

[0065] A plurality of spray pipes 900 are provided at the bottom of the mounting plate 100 of the continuous casting equipment for various metal alloys and are evenly distributed around the through hole 110 on the mounting plate 100. A plurality of evenly distributed spray heads 910 are provided on the wall of each spray pipe 900 facing the through hole 110.

[0066] This embodiment provides a solution by providing a spray pipe 900 at the bottom of the mounting plate 100 to secondary cool the molten metal with the shell emerging from the copper tube 200, thereby promoting the thickening and strength of the shell and facilitating subsequent processing. 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, ensuring a uniform distribution of cooling intensity during the secondary cooling process. This prevents stress concentration caused by localized overheating or overcooling of the shell and reduces the risk of cracking.

[0067] The specific working process of the continuous casting equipment for various metal alloys provided by the present invention is described in combination with the above embodiments: The hot molten metal flows into the copper tube 200 from above, then flows downward within the copper tube 200, where its surface is cooled by the sidewalls of the copper tube 200 to form a shell. After the shell-forming molten metal leaves the copper tube 200, it passes through the through-hole 110 and falls into the spray pipes. It is then cooled again by the coolant sprayed from the nozzle 910, further thickening the shell.

[0068] As the hot molten metal flows through the copper tube 200, the motor 600 starts, driving the transmission wheel 750 to rotate. The transmission wheel 750, through the meshing of the bevel teeth, drives the third rotating drum 700 to rotate. The rotation of the third rotating drum 700, through the engagement of the clamping block 530 and the clamping 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 downward.

[0069] The rotation of the second rotating drum 500 simultaneously drives the connecting plate 520 and the supporting foot 800 to rotate. As the supporting foot 800 rotates with the second rotating drum 500, the bottom end of the supporting foot 800 slides along the upper surface of the vibration disk 130, thereby pushing the connecting plate 520 to move up and down. The connecting plate 520 moves up and down, driving 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 supporting foot 800 rotates with the second rotating drum 500, it also moves along the connecting rod 522 under the action of centrifugal force. The greater the rotation speed of the second rotating drum 500, the higher the vibration frequency of the copper tube 200, and the closer the supporting foot 800 is to the outer periphery of the vibration disk 130 under the action of centrifugal force, making the amplitude of the copper tube 200 smaller.

[0070] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, 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.

[0071] The above-described embodiments merely illustrate several embodiments of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
