[0003] Magnesium alloy ingot production mainly relies on continuous casting technology, and at the end of each casting cycle, a key and difficult link of ingot demolding is faced.

[0052] In order to make the technical problems to be solved by the present application, technical solutions and beneficial effects clearer, the present application will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, and are not used to limit the present application.

[0053] Please refer to Figures 1 to 9The magnesium alloy continuous casting system is described. The magnesium alloy continuous casting system comprises a grouting unit 10, a crystallization unit 20 and a conveying unit 30. The grouting unit 10 is connected to a grouting nozzle 101 of a raw magnesium liquid pool and a switch piece 102 arranged at an opening of the grouting nozzle 101. The switch piece 102 is used to open and close the opening of the grouting nozzle 101. The crystallization unit 20 comprises a plurality of crystallizers, a hoop 204 slidingly arranged at the outer periphery of the crystallizers and a moving assembly 205 connected to the hoop 204. The crystallizer comprises a crystallization base 201, a crystallization side plate 202 corresponding to the edge line of the crystallization base 201 and a jacking piece 203 arranged between the crystallization base 201 and the crystallization side plate 202. The crystallization side plate 202 is rotationally connected to the edge line of the crystallization base 201. The rotation axis of the crystallization side plate 202 is parallel to the edge line of the corresponding crystallization base 201. The jacking piece 203 is used to drive the rotation of the crystallization side plate 202. The moving assembly 205 is used to drive the hoop 204 to move in a direction perpendicular to the seat surface of the crystallization base 201. The conveying unit 30 is connected to the plurality of crystallizers. The conveying unit 30 extends in a first direction. The conveying unit 30 is a circulating and reciprocating track belt, which is used to drive the crystallizers to reciprocally move in the first direction.

[0054] It should be noted that the grouting unit 10 further comprises a moving piece 105, which is used to drive the grouting nozzle 101 to move up and down. The magnesium liquid grouting working area is connected to a protective gas such as argon through a pipeline, so as to reduce the explosion safety hidden danger.

[0055] Optionally, the switch piece 102 can be a valve.

[0056] Optionally, referring to Figure 4 , the switch piece 102 can also be a plug. The grouting nozzle 101 is conical.

[0057] When the grouting nozzle 101 is inserted into the crystallizer and abuts against the crystallization base 201, the plug is pushed back. At this time, there is a gap between the plug and the inner wall of the grouting nozzle 101, and the magnesium liquid can flow out. When the grouting nozzle 101 is pulled out of the crystallizer, the plug naturally falls. At this time, there is no gap between the plug and the inner wall of the grouting nozzle 101, and a closed opening is formed, so that the magnesium liquid cannot flow out.

[0058] The magnesium alloy continuous casting system provided by the embodiment is characterized in that when the crystallizer moves to below the pouring nozzle 101, the switch 102 opens the pouring nozzle 101, and the original magnesium liquid is poured into the crystallizer; after the pouring is completed, the conveying unit 30 drives the crystallizer loaded with the liquid magnesium alloy to move away from the pouring station along the first direction, and meanwhile, the adjacent empty crystallizer is dispatched to the pouring station for continuous operation, forming a flow line; in the process of returning to the pouring station, the moving assembly 205 removes the restraint of the hoop 204 on the crystallizing side plate 202, so that the lifting piece 203 drives the crystallizing side plate 202 to rotate, and the crystallizing side plate 202 is separated from the ingot blank; after the demolding, the moving assembly 205 resets the hoop 204 to make the crystallizing side plate 202 re-enclose, and the conveying unit 30 sends it back to the pouring station for recycling.

[0059] Compared with the prior art, when one crystallizer completes pouring and enters the solidification stage, the conveying unit 30 can move it away from the pouring station and dispatch the empty crystallizer for relay operation; in the process of returning of the conveying unit 30 with the crystallizer, the opening of the crystallizer faces downward, and the magnesium liquid in the crystallizer has been solidified to form an ingot blank, and then the moving assembly 205 starts to move the hoop 204 from the crystallizing side plate 202 to the crystallizing base 201, at this time, the lifting piece 203 drives the crystallizing side plate 202 to rotate, so that the crystallizing side plate 202 is separated from the ingot blank. The present application innovates the “mechanical demolding” to “geometric demolding”, and changes the system constraint mode by the movability of the crystallizing side plate 202, which fundamentally avoids the problem of shell stress concentration caused by forced demolding in the traditional process, avoids the problem of cracks or even breakage caused by forced demolding, and improves the quality of the magnesium alloy ingot blank; meanwhile, combined with the multi-station circulating transportation, the efficient and continuous production of the magnesium alloy continuous casting is realized on the premise of ensuring that the surface of the ingot blank is not damaged and the inside is not cracked, which provides an equipment foundation for the large-scale application of magnesium alloy in the lightweight field.

[0060] In some embodiments, referring to Figure 2 , Figure 7 and Figure 8 , the conveying unit 30 comprises a first conveying machine 301, a plurality of discharging seats 302 and a second conveying machine 303; the first conveying machine 301 is connected to the plurality of crystallizers, and is used to drive the crystallizers to reciprocally move along the first direction; the plurality of discharging seats 302 correspond to the crystallizers one by one, the surface of the discharging seat 302 is inwardly recessed to form a lifting cavity 3021, a lifting plate 3022 is slidably arranged on the inner wall of the lifting cavity 3021, a resilient member 3023 is fixedly connected between the lifting plate 3022 and the discharging seat 302, and the resilient member 3023 has a pre-tightening force for moving the lifting plate 3022 outward of the lifting cavity 3021; the second conveying machine 303 is arranged below the first conveying machine 301, and is connected to the plurality of discharging seats 302 and used to drive the discharging seats 302 to reciprocally move along the first direction.

[0061] It should be noted that the first conveyor 301 and the second conveyor 303 can be a belt conveyor or a chain conveyor.

[0062] Specifically, the elastic member 3023 can be a spring or a damper.

[0063] Specifically, the elastic member 3023 can be a spring or a damper.

[0064] Through the first conveyor 301 and the second conveyor 303, the overlapping optimization of solidification waiting time and logistics time is realized. When the crystallizer completes pouring at the pouring station, the first conveyor 301 can immediately move it into the solidification area, while the standby crystallizer is dispatched to continue pouring. At the same time, the ingot billet that has completed demolding falls into the discharge seat 302 and is carried by the second conveyor 303 to the ingot clamping robot, which takes out the ingot billet and neatly stacks it, and the double-line parallel meets the needs of large-scale production.

[0065] In some embodiments, referring to Figure 5 , the plurality of crystallization side plates 202 enclose the pouring area, and the crystallizer further comprises a guide column 206 arranged between two adjacent crystallization side plates 202, the guide column 206 is fixedly connected with the crystallization base 201, and the guide column 206 is provided with a guide groove 2061 at a corner facing the pouring area.

[0066] During the demolding and falling process of the ingot billet, the guide groove 2061 limits the ingot billet, ensuring the vertical falling track of the ingot billet, thereby ensuring that the ingot billet falls into the receiving plate 501.

[0067] In some embodiments, referring to Figure 5 , the transport unit 30 further comprises a transport seat 304 arranged between the crystallization base 201 and the first conveyor 301, and the transport seat 304 is detachably connected with the crystallization base 201.

[0068] Optionally, the transport seat 304 and the crystallization base 201 can be detachably connected by bolts or electric suction cups.

[0069] The transport seat 304 is detachably connected with the crystallization base 201, so that different shapes of crystallizers can be replaced according to production requirements, and the detachable structure between the transport seat 304 and the crystallization base 201 is simple, and the disassembly efficiency is improved.

[0070] In some embodiments, referring to Figure 7 , the surface of the lifting plate 3022 is provided with a centering unit 40; the centering unit 40 includes a plurality of centering plates 401 and a plurality of telescopic members 402; the plurality of centering plates 401 correspond one-to-one to the edges of the lifting plate 3022, the plate surface of the centering plate 401 is parallel to the plate surface of the crystallization side plate 202, and the centering plate 401 is slidably arranged on the blanking seat 302 and moves in a direction perpendicular to the plate surface thereof; the plurality of telescopic members 402 correspond one-to-one to the centering plates 401, and the telescopic direction of the telescopic member 402 is perpendicular to the plate surface of the corresponding centering plate 401.

[0071] It should be noted that the telescopic member 402 can be a telescopic oil cylinder or a hydraulic cylinder.

[0072] The telescopic member 402 is simultaneously started to drive the centering plate 401 to move, so that the centering plate 401 pushes the ingot blank to the center position of the lifting plate 3022, thereby facilitating the blanking of the ingot robot.

[0073] In some embodiments, referring to Figure 1 and Figure 5 , the outer side of the crystallization side plate 202 is provided with a chute 2021, and the magnesium alloy continuous casting system further includes a receiving unit 50; the receiving unit 50 includes a receiving plate 501 and two pushing members 502; the receiving plate 501 has a sliding block 5011 which is slidably matched with the chute 2021; the two pushing members 502 are respectively arranged at the two ends of the first conveyer 301, and the telescopic direction of the pushing member 502 is perpendicular to the first direction, wherein one of the pushing members 502 is used to push the receiving plate 501 into two adjacent crystallizers, and the other pushing member 502 is used to push the receiving plate 501 out of the two adjacent crystallizers.

[0074] Specifically, the receiving unit 50 further includes a feeding table 503 and a blanking table 504, one of the pushing members 502 pushes the receiving plate 501 placed on the surface of the feeding table 503 into the adjacent two crystallizers, and the other pushing member 502 pushes the receiving plate 501 between the adjacent two crystallizers onto the blanking table 504, and then the worker collects the magnesium skin in the receiving plate 501 for waste treatment, and finally places the cleaned receiving plate 501 on the feeding table 503.

[0075] It should be noted that the pushing member 502 can be a telescopic oil cylinder or a hydraulic cylinder, and the receiving plate 501 is an arc-shaped plate.

[0076] After long time work, the sealing of the plug is not good, so magnesium liquid may drip during the movement of the crystallizer. The receiving plate 501 is arranged between two adjacent crystallizers. If magnesium liquid drips, the magnesium liquid will fall on the receiving plate 501, which is convenient for collection and prevents the magnesium liquid from contacting water.

[0077] The crystallization side plate 202 is separated from the ingot blank after the restraint of the hoop 204 on the crystallization side plate 202 is removed, so that forced demolding is avoided, and the quality of the magnesium alloy ingot blank is improved. However, the crystallization side plate 202 needs space to rotate, so the distance between the crystallizers is increased, which increases the possibility of magnesium liquid dripping onto the track. The receiving plate 501 is arranged between two crystallizers, so that the magnesium liquid that drips will fall on the receiving plate 501, thereby improving the problem of ingot blank demolding and reducing the possibility of magnesium liquid dripping onto the track.

[0078] In some embodiments, referring to Figure 9 The receiving unit 50 further comprises a suction accessory 505 arranged between the pushing member 502 and the receiving plate 501, and the suction accessory 505 is used to suction and fix the pushing member 502 and the receiving plate 501.

[0079] It should be noted that the suction accessory 505 can be an electric suction cup.

[0080] Optionally, the suction accessory 505 can be arranged at the end of the pushing member 502.

[0081] Optionally, the suction accessory 505 can be arranged at the end of the receiving plate 501.

[0082] The pushing member 502 and the receiving plate 501 are fixed by the suction accessory 505, which improves the movement stability of the receiving plate 501 and ensures the movement trajectory of the receiving plate 501.

[0083] In some embodiments, referring to Figure 3 The magnesium alloy continuous casting system further comprises a skin scraping unit 60; the skin scraping unit 60 comprises a scraper 601, a collection barrel 602, and a manipulator 603; the scraper 601 is arranged on the front side of the grouting nozzle 101; the manipulator 603 is connected to the scraper 601 and is used to drive the scraper 601 to scrape off the magnesium skin in the crystallizer and transfer the magnesium skin to the collection barrel 602.

[0084] The magnesium skin that has been oxidized is removed by the scraper 601, which improves the finished product quality of the ingot blank; and the magnesium skin is uniformly placed in the collection barrel 602, which is convenient for subsequent workers to clean.

[0085] In some embodiments, referring to Figure 3The outer wall of the collecting barrel 602 is slidably provided with a T-shaped rod 6021 which moves in the up-down direction. A deformation member 6022 is fixedly connected between the T-shaped rod 6021 and the collecting barrel 602, and the deformation member 6022 has a pre-tightening force for moving the T-shaped rod 6021 upward. When the scraper 601 is moved to above the collecting barrel 602 by the manipulator 603, the manipulator 603 reciprocally moves up and down and hits the T-shaped rod 6021.

[0086] The vibration is generated by the hitting, and is transmitted to the scraper 601, so that the magnesium skins adhered to the scraper 601 are all dropped, and the residual magnesium skins on the scraper 601 are avoided.

[0087] In some embodiments, referring to Figure 3 The grouting unit 10 further comprises a liquid level meter 103 and a driving member 104. The driving member 104 is connected to the liquid level meter 103, and is used for inserting the liquid level meter 103 into the crystallizer or pulling the liquid level meter 103 out of the crystallizer.

[0088] Optionally, the driving member 104 is linear motion, and the driving member 104 can be a telescopic oil cylinder or a hydraulic cylinder.

[0089] Optionally, referring to Figure 3 The driving member 104 is rotary motion, and the driving member 104 can be a servo motor.

[0090] When the grouting nozzle 101 falls, the driving member 104 starts to insert the liquid level meter 103 into the crystallizer. When the liquid surface in the crystallizer reaches the preset height of the liquid level meter 103, the liquid level meter 103 transmits a starting signal to a moving member 105. After the moving member 105 receives the starting signal, the moving member 105 drives the grouting nozzle 101 to move upward. At the same time, the driving member 104 starts to pull the liquid level meter 103 out of the crystallizer.
