Description

Technical Field

[0001] This invention relates to the field of continuous casting technology, and in particular to a structure for guiding the cooling and crystallization of molten copper in continuous casting. Background Technology

[0002] In the continuous casting process of copper materials, molten copper is injected into the crystallizer and gradually solidifies into a copper rod under cooling. The rod is then continuously conveyed downwards by the casting mechanism. In traditional processes, the crystallizer, as the core guiding structure for the cooling and forming of molten copper, has a continuous relative motion between its inner wall and the solidifying copper rod. This friction not only causes mechanical wear on the inner wall material of the crystallizer but also creates resistance to the downward movement of the copper rod, affecting the stability of casting. At the same time, in the early stage of solidification, the high-temperature molten copper is prone to local adhesion to the inner wall of the crystallizer, interfering with the uniform formation of the initial billet shell and even causing billet defects or production interruptions. These phenomena together constitute the key factors affecting equipment life, product quality, and process stability in the continuous casting process. Summary of the Invention

[0003] This invention provides a cooling and crystallization guiding structure for copper liquid in continuous casting, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] A continuous casting copper liquid cooling and crystallization guiding structure includes a transition channel connected to the bottom of an external tundish, a crystallizer connected to the bottom of the transition channel, and a plurality of vertically arranged shaping tube sections. The shaping tube sections are composed of a plurality of spliced ​​bodies distributed in a circumferential manner, and the spliced ​​bodies in the shaping tube sections below the crystallizer are separated from each other.

[0006] The assembled components within the shaped tube section are combined in the intermediate package, and the shaped tube sections are sequentially connected and continuously pass through the transition channel and the crystallizer.

[0007] Furthermore, in the vertical direction, the inner wall shape of the shaped pipe section is an inverted cone.

[0008] Furthermore, the top and bottom of the splice body are respectively provided with a slot and a right-angle hook, and the two splice bodies in adjacent shaping pipe sections are connected by the slot and the right-angle hook.

[0009] Furthermore, the assembly has a cooling chamber for cooling inside, and an insertion tube is provided on one side wall of the assembly at the docking position of two adjacent assemblies, and an insertion hole communicating with the cooling chamber is opened on the other side wall of the assembly. The insertion tube and the insertion hole are used in conjunction.

[0010] Each of the splicing bodies has an opening on its outer wall that communicates with the cooling chamber, and the opening is sealed by a sealing plate.

[0011] Furthermore, grooves are provided on the inner wall of the cooling chamber.

[0012] Furthermore, the number of splicing bodies within the shaped tube section is set to two. The opening direction of the sealing plate on one splicing body faces the interior of the cooling chamber, and the opening direction of the sealing plate on the other splicing body faces the exterior of the splicing body. The sealing plate and the splicing body are connected by an elastic body.

[0013] The crystallizer includes a sleeve, two gas grooves formed on the inner wall of the sleeve, and two gas pipes respectively connected to the two gas grooves. The movement trajectories of the gas grooves and the openings on the splicing body are correspondingly set.

[0014] Furthermore, a tapered opening is provided on the inner wall of the splicing body, facing the inner side of the shaped tube section. The tapered opening is connected to the cooling chamber and is sealed by a sealing plate II. The sealing plate II is coplanar with the inner wall of the splicing body. A prism is provided on the sealing plate II. The end of the prism extends to the outer wall of the splicing body and slides relative to the splicing body. The prism is connected to the splicing body through several elastic bodies II.

[0015] A pushing structure is provided in the air groove to provide a constant thrust to the prism shaft. When the second sealing plate moves, the second sealing plate squeezes and deforms the copper rod that has been initially shaped in the splicing body. The cooling gas in the cooling chamber flows out through the conical opening.

[0016] Furthermore, the pushing structure includes a plurality of cylinders arranged vertically, each cylinder having a slide rod on its movable end. The slide rod is vertical, and a sliding sleeve is slidably mounted on the slide rod. The sliding sleeve is connected to the slide rod by a spring, and a top post is provided on the sliding sleeve for use in conjunction with the prism shaft.

[0017] Furthermore, the shaped tube section has a polygonal shape, and both the transition channel and the crystallizer are used in conjunction with the shape of the shaped tube section.

[0018] Furthermore, the guiding structure also includes a power unit for adjusting the moving speed of the shaping tube section. The power unit includes a fixed frame fixed relative to the crystallizer, a movable frame slidably disposed on the fixed frame, and a plurality of rollers arranged on the movable frame. The rollers are in driving contact with the outer wall of the shaping tube section. The fixed frame and the movable frame are connected by an elastic body. The rollers rotate on the movable frame, and adjacent rollers are driven by a power wheel.

[0019] The technical solution of this invention can achieve the following technical effects:

[0020] This effectively solves the problem of relative friction between the cured copper rod and the crystallizer, facilitating the protection of the copper rod and preventing damage to the outer shell of the copper rod, which could lead to the outflow of uncured copper liquid and thus affect the smooth production of the copper rod. At the same time, by using the synchronous movement of the shaping tube section with the copper liquid and copper rod, the relative movement and adhesion between the copper liquid and the inner wall of the shaping tube section can be avoided, facilitating the smooth forming of the shell. There is no relative friction between the copper rod and the shaping tube section, which facilitates the smooth conversion of the copper liquid into copper rod and avoids friction from hindering the copper rod conveying process.

[0042] 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.

[0043] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0044] like Figures 1 to 4 As shown, this application provides a cooling and crystallization guiding structure for continuous casting copper liquid, including a transition channel 200 connected to the bottom of an external tundish 100, a crystallizer 300 connected to the bottom of the transition channel 200, and a plurality of vertically arranged shaping tube sections 400. The shaping tube section 400 is composed of a plurality of spliced ​​bodies 401 distributed in a circumferential manner, and the plurality of spliced ​​bodies 401 in the shaping tube section 400 below the crystallizer 300 are separated from each other.

[0045] Several splice bodies 401 within the shaped tube section 400 are assembled within the intermediate package 100, and the several shaped tube sections 400 are sequentially connected and continuously pass through the transition channel 200 and the crystallizer 300.

[0046] Specifically, the tundish 100, transition channel 200, and crystallizer 300 are arranged vertically in sequence. The transition channel 200 is used to connect the crystallizer 300 and provide guidance for the shaping tube section 400. The crystallizer 300 can cool the shaping tube section 400 that passes through and moves within it. The shaping tube section 400 can be placed into the molten copper in the tundish 100 and transported downwards through the transition channel 200 and the crystallizer 300. In order for the molten copper in the tundish 100 to enter the shaping tube section 400, the height of the shaping tube section 400 can be less than the depth of the molten copper. That is, when the shaping tube section 400 is placed into the tundish 100, the molten copper level is higher than the top of the shaping tube section 400, and the molten copper will naturally flow into the shaping tube section 400. Alternatively, several splice bodies 401 in the shaping tube section 400 can be placed dispersedly into the molten copper in the tundish 100 and then assembled into the shaping tube section 400. At this time, the molten copper naturally exists in the shaping tube section 400.

[0047] In use, several shaped tube sections 400 sequentially pass through the tundish 100, the transition channel 200, and the crystallizer 300 and are conveyed downwards. Adjacent shaped tube sections 400 abut against each other, thereby forming a tube body of a certain length. On the upper side of the tundish 100, several splice bodies 401 within the shaped tube sections 400 are combined and inserted into the transition channel 200. At this time, the bottom of the shaped tube section 400 abuts against the top of the original shaped tube sections 400 in the transition channel 200 and moves downwards synchronously. The splice bodies 401 within the shaped tube section 400 that have moved to below the crystallizer 300 can separate from each other. This achieves the combined downward movement of the shaped tube sections 400 on the upper side of the tundish 100 and the disassembly on the lower side of the crystallizer 300, allowing several shaped tube sections 400 to continuously pass through the tundish 100. The intermediate package 100, transition channel 200, and crystallizer 300 are connected. The molten copper in the intermediate package 100 flows into the corresponding shaping tube section 400. At this time, the downward-moving shaping tube section 400 moves downward synchronously with the molten copper inside. When it passes the position of the crystallizer 300, the crystallizer 300 cools the shaping tube section 400 and the molten copper inside to form a copper rod. The solidified copper rod will block the molten copper above it, thereby restricting the flow of molten copper and enabling it to move synchronously with the shaping tube section 400. Due to the friction between the copper rod and the inner wall of the shaping tube section 400, the copper rod and the shaping tube section 400 also move synchronously. When the shaping tube section 400 moves to below the crystallizer 300, the several splicing bodies 401 inside the shaping tube section 400 separate from each other and separate from the copper rod, thereby realizing the static guidance of the copper rod.

[0048] It should be noted that, in order to achieve the assembly of several splice bodies 401 on the upper side of the intermediate tundish 100 and the disassembly on the lower side of the crystallizer 300 in the shaped tube section 400, a robotic arm or other structure capable of achieving the above purpose can be set on both the upper side of the intermediate tundish 100 and the lower side of the crystallizer 300. When several splice bodies 401 are disassembled, the splice bodies 401 can be transferred to an external storage warehouse for temporary storage. When several splice bodies 401 need to be assembled, they can be retrieved from the storage warehouse. Of course, the disassembled splice bodies 401 can also be directly transferred to the upper side of the intermediate tundish 100 and assembled through a transfer structure, thereby realizing the continuous use of several shaped tube sections 400.

[0049] In the initial stage, since there is no solidified copper rod inside the shaping tube section 400, it is necessary to set a guide head inside the crystallizer 300 or at the bottom of the shaping tube section 400 to seal the shaping tube section 400. After the copper liquid inside the shaping tube section 400 solidifies, the guide head can be removed.

[0050] Since the shaping tube section 400 needs to pass through the area where the copper liquid is located, the outer wall of the shaping tube section 400 will be in direct contact with the copper liquid. In order to prevent the copper liquid from adhering to the outer wall of the shaping tube section 400 and passing through the transition channel 200 and the crystallizer 300, a scraper can be set at the position where the inner wall of the tundish 100 connects to the top of the transition channel 200 to scrape off the copper liquid on the outer wall of the shaping tube section 400, keeping the outer wall of the shaping tube section 400 clean. Alternatively, inert gas can be filled into the gap between the inner wall of the transition channel 200 and the outer wall of the shaping tube section 400, so that the gas flows upward and downward. The upward flowing gas will move into the tundish 100 and form an air seal in the area where the outer wall of the shaping tube section 400 contacts the copper liquid at the top of the transition channel 200. This can also isolate the copper liquid and achieve the cleaning of the outer wall of the shaping tube section 400. Of course, other structures that can achieve the above objectives can also be used in this invention.

[0051] The technical solution of this invention effectively solves the problem of relative friction between the cured copper rod and the crystallizer 300, facilitating the protection of the copper rod and preventing damage to the outer shell of the copper rod, which could lead to the outflow of the uncured copper liquid inside and thus affect the smooth production of the copper rod. At the same time, by using the method of synchronous movement of the shaping tube section 400 with the copper liquid and the copper rod, the relative movement and adhesion between the copper liquid and the inner wall of the shaping tube section 400 can be avoided, facilitating the smooth forming of the shell. There is no relative friction between the copper rod and the shaping tube section 400, which facilitates the smooth conversion of the copper liquid into the copper rod and avoids friction from hindering the copper rod conveying operation.

[0052] Furthermore, when the molten copper cools into a copper rod, due to thermal expansion and contraction, the copper rod will separate from the inner wall of the shaping tube section 400, creating a small gap between them. If the inner wall of the shaping tube section 400 is a regular cylinder, it cannot use friction to restrict the downward transport of the copper rod, and the copper rod may fall naturally, causing the molten copper to flow out directly before solidification. Additionally, the heat transfer efficiency between the shaping tube section 400 and the copper rod decreases. To solve this problem, the shape of the inner wall of the shaping tube section 400 can be specially designed. Specifically, in the vertical direction, the inner wall of the shaping tube section 400 is an inverted cone. This inverted cone shape allows the inner wall of the shaping tube section 400 to still contact the corresponding area of ​​the outer wall of the copper rod after the copper rod's diameter is reduced, thus facilitating the restriction of the downward transport speed of the copper rod and ensuring a consistently high heat transfer efficiency between the shaping tube section 400 and the copper rod.

[0053] Furthermore, to achieve continuous vertical movement of the shaping tube sections 400, especially those located in the transition channel 200 and the crystallizer 300, which cannot contact other external structures, movement can only be achieved by pressing down on the upper shaping tube sections 400 or pulling down on the lower shaping tube sections 400. When using the pressing method, a robotic arm located on the upper side of the intermediate package 100 can directly push the shaping tube sections 400 located in the intermediate package 100 downwards, thereby pressing down the shaping tube sections 400 one by one. However, this method requires limiting the moving speed of the shaping tube sections 400 on the lower side of the crystallizer 300 to prevent them from falling naturally. When using the pulling method, a robotic arm located on the lower side of the crystallizer 300 can pull the corresponding shaping tube sections 400. As the shaping tube section 400 moves downwards, the corresponding shaping tube sections 400 within the intermediate liner 100, transition channel 200, and crystallizer 300 can fall naturally under gravity. However, this method can easily cause adjacent shaping tube sections 400 to separate, meaning the lower shaping tube section 400 moves too quickly or the upper shaping tube section 400 moves at a limited speed. Alternatively, a connecting structure can be used to connect adjacent shaping tube sections 400, thereby improving synchronization. Specifically, the top and bottom of the splicing body 401 are respectively provided with a slot 402 and a right-angle hook 403, and the two corresponding splicing bodies 401 within adjacent shaping tube sections 400 are connected through the slot 402 and the right-angle hook 403. The slot 402 and the right-angle hook 403 can respectively... Figure 3 and Figure 4 As shown in the structure, the right-angle hook 403 at the bottom of the upper splicing body 401 can be vertically inserted into the slot 402 at the top of the lower splicing body 401. With relative rotation of the two splicing bodies 401, the right-angle hook 403 and the slot 402 complete the engagement. At this time, the two splicing bodies 401 are firmly connected in the vertical direction. This method can make the movement trajectory of the splicing body 401 during disassembly conform to the shape requirements of the copper rod.

[0054] Furthermore, the splicing body 401 has a cooling chamber 404 inside for cooling. At the docking position of two adjacent splicing bodies 401, one splicing body 401 is provided with an insertion tube 405 on its side wall, and the other splicing body 401 is provided with an insertion hole 406 communicating with the cooling chamber 404 on its side wall. The insertion tube 405 and the insertion hole 406 are used together.

[0055] Each splice 401 has an opening on its outer wall that communicates with the cooling chamber 404, and the opening is sealed by a sealing plate 407.

[0056] like Figures 5 to 6As shown, when the two splicing bodies 401 in the shaping tube section 400 are joined, the insertion tube 405 on one splicing body 401 can be inserted into the insertion hole 406 on the other splicing body 401. Thus, the two splicing bodies 401 are interconnected through the insertion tube 405 and the insertion hole 406, and several cooling chambers 404 are sequentially connected. When the shaping tube section 400 moves to the position of the crystallizer 300, the cooling gas or liquid in the crystallizer 300 can enter the cooling chamber 404 through the opening on one of the splicing bodies 401. The cooling gas or liquid in 04 can cool the splice 401, thereby cooling the copper rod and copper liquid, and the cooling gas or liquid can flow between several cooling chambers 404; the sealing plate 407 can block the opening to prevent the copper liquid from entering the cooling chamber 404 through the opening when the shaping tube section 400 is in the tundish 100; in order to realize the recycling of cooling gas or liquid, the two openings on two splice 401s can be used as air inlet and air outlet respectively.

[0057] In practical use, the splice body 401 can be processed by splicing and welding several plates or by bolting.

[0058] Furthermore, such as Figure 6 As shown, in order to improve the heat exchange effect and increase the heat exchange area, a groove 411 can be provided on the inner wall of the cooling chamber 404, so that the cooling gas or liquid can contact the inner wall of the cooling chamber 404 over a larger area; the groove 411 can be vertically set, horizontally set or inclined, and the groove 411 can be straight, wavy or other arbitrary shapes.

[0059] Furthermore, the number of splicing bodies 401 inside the shaping tube section 400 is set to two. The opening direction of the sealing plate 407 on one splicing body 401 faces the inside of the cooling chamber 404, and the opening direction of the sealing plate 407 on the other splicing body 401 faces the outside of the splicing body 401. The sealing plate 407 and the splicing body 401 are connected by an elastic body 409.

[0060] The crystallizer 300 includes a sleeve 301, two air grooves 302 formed on the inner wall of the sleeve 301, and two air pipes 303 respectively connected to the two air grooves 302. The movement trajectories of the air grooves 302 and the openings on the splicing body 401 are correspondingly set.

[0061] by Figure 7Taking the opening method of the sealing plate 407 towards the inside of the cooling chamber 404 as an example, a baffle groove is provided in the inner wall area of ​​the cooling chamber 404 where the opening is located. The sealing plate 407 is provided with an outer edge 410 that cooperates with the baffle groove. In this way, the baffle groove and the outer edge 410 can prevent the sealing plate 407 from moving outward of the splice 401, while allowing the sealing plate 407 to move towards the inside of the cooling chamber 404. Thus, the opening direction of the sealing plate 407 can be restricted. Similarly, the sealing plate 407 on the other splice 401 that opens outward and its opening adopt the same method to restrict the opening direction of the sealing plate 407. The elastic body 409 can provide elastic force for the sealing plate 407. The elastic body 409 on the sealing plate 407 that opens towards the inside of the cooling chamber 404 provides elastic thrust for the sealing plate 407, while the elastic body 409 on the sealing plate 407 that opens towards the outside provides elastic tension for the sealing plate 407.

[0062] To prevent the sealing plate 407 from moving arbitrarily and failing to accurately reset when opened, several guide groups can be installed in the cooling chamber 404. These guide groups are arranged in a ring and each guide group consists of two support arms 408 that are rotatably connected to each other. The two support arms 408 are rotatably connected to the sealing plate 407 and the inner wall of the cooling chamber 404, respectively. Furthermore, the rotation axes of the support arms 408 in adjacent guide groups are perpendicular to each other. By using the mutual restriction of these guide groups, the sealing plate 407 can only move in a straight line.

[0063] like Figure 9 As shown, the positions of the two air grooves 302 inside the sleeve 301 correspond to the positions of the openings on the two splicing bodies 401. When the shaping tube section 400 moves into the crystallizer 300, the opening moves to the area where the air groove 302 is located. At this time, one air pipe 303 introduces cooling gas into the corresponding air groove 302. The air pressure in the air groove 302 increases and pushes the sealing plate 407 on the corresponding splicing body 401 to open towards the inside of the cooling chamber 404. At this time, the cooling gas can smoothly enter the cooling chamber 404. Since the two cooling chambers 404 are interconnected, the cooling gas can fill both cooling chambers 404. The air pressure in the other cooling chamber 404 will push the sealing plate 407 on it to open towards the outside of the splicing body 401. At this time, the cooling gas can flow into the other air groove 302 and be discharged through the corresponding air pipe 303, thereby allowing the cooling gas to flow smoothly and continuously.

[0064] It should be noted that, in order to provide prolonged cooling of the copper rod, the air groove 302 can be configured as follows when the shaping tube section 400 passes through the crystallizer 300 and moves. Figure 9The elongated shape shown ensures that the opening can always communicate with the air groove 302 within a large range of movement of the shaped tube section 400. To improve the flow of cooling gas in the two cooling chambers 404, the opening can be set on the lower side of the side wall of the splice body 401, and the insertion tube 405 and insertion hole 406 can be set near the top of the splice body 401. This allows the cooling gas to flow vertically in the cooling chamber 404, making it easy for the movement path of the cooling gas to fully cover the internal space of the cooling chamber 404.

[0065] Furthermore, the inner wall of the splicing body 401 is provided with a tapered opening facing the inside of the shaping tube section 400. The tapered opening is connected to the cooling chamber 404 and is sealed by a sealing plate 412. The sealing plate 412 is coplanar with the inner wall of the splicing body 401. A prism 413 is provided on the sealing plate 412. The end of the prism 413 extends to the outer wall of the splicing body 401 and slides relative to the splicing body 401. The prism 413 is connected to the splicing body 401 through several elastic bodies 414.

[0066] A push structure is provided in the air groove 302 to provide a constant thrust to the prism shaft 413. When the sealing plate 412 moves, the sealing plate 412 squeezes the copper rod that is initially shaped in the splice body 401 and deforms it. The cooling gas in the cooling chamber 404 flows out through the cone opening.

[0067] like Figure 5 and Figure 8 As shown, in its natural state, the elastic body 414 pushes the sealing plate 412 to seal the conical opening through the prism 413, the inner wall of the splice 401 remains flat, and the air pressure of the cooling gas inside the cooling chamber 404 cannot push the sealing plate 412 to move; the prism 413 can guide the sealing plate 412. In order to allow the sealing plate 412 to move a specified distance, an auxiliary sleeve can be set on the outer wall of the prism 413, and the auxiliary sleeve is installed on the inner wall of the cooling chamber 404.

[0068] When the prism shaft 413 moves with the splicing body 401 to the area where the air groove 302 is located, the pushing structure can push the prism shaft 413 to move. The prism shaft 413 drives the sealing plate 412 to move synchronously. The sealing plate 412 moves towards the inside of the shaping tube section 400 and squeezes the copper rod that has been initially shaped inside the shaping tube section 400. The pushing structure provides a constant thrust to the sealing plate 412. When the copper rod has a high hardness, the deformation of the copper rod is small. At this time, the moving distance of the sealing plate 412 is small, the opening of the cone is small, and the cooling gas in the cooling chamber 404 is discharged through the cone. When the quantity is small, the opening of the cone is larger, and a larger amount of cooling gas enters the shaping tube section 400. Therefore, by detecting the pressure and flow rate of the gas inside the two gas pipes 303, the leakage of cooling gas entering the shaping tube section 400 can be detected, thereby detecting the hardness of the copper rod. When the hardness of the copper rod is small, the moving speed of the shaping tube section 400 can be adjusted to regulate the copper rod conveying speed, which facilitates extending the cooling time of the copper rod and prevents the copper rod from being pulled out directly before it has been cured to the specified degree when its hardness is small.

[0069] It should be noted that the cooling gas entering the shaping tube section 400 through the conical opening can directly cool the copper rod, and the gas can fill the space between the copper rod and the inner wall of the shaping tube section 400, thus facilitating demolding; the shape characteristics of the conical opening allow the cooling gas to be discharged through the gap between the inner wall of the conical opening and the sealing plate 412 when the sealing plate 412 moves, and the moving distance of the sealing plate 412 is directly related to the size of the gap.

[0070] Furthermore, the actuating structure includes several vertically arranged cylinders 304, each cylinder 304 having a sliding rod 305 on its movable end. The sliding rod 305 is vertical, and a sliding sleeve 306 is slidably mounted on the sliding rod 305. The sliding sleeve 306 is connected to the sliding rod 305 by a spring 307, and a top post 308 for cooperating with the prism shaft 413 is provided on the sliding sleeve 306.

[0071] like Figure 10 As shown, cylinder 304 can push slide rod 305 to move. Slide rod 305 pushes top column 308 towards prism shaft 413 through sliding sleeve 306. The end of top column 308 abuts against prism shaft 413 and pushes prism shaft 413 to move, thereby providing moving power for sealing plate 2 412. Since shaping tube section 400 is in a moving state, and part of top column 308 will be inserted into auxiliary sleeve on prism shaft 413, shaping tube section 400 can push top column 308 to move synchronously. Sliding sleeve 306 slides on slide rod 305, and spring 307 undergoes elastic deformation. Thus, continuous detection can be achieved within a certain range of movement of shaping tube section 400. When prism shaft 413 moves, the end of prism shaft 413 needs to always be located in auxiliary sleeve, thereby preventing cooling chamber 404 and air groove 302 from communicating with each other through auxiliary sleeve.

[0072] Furthermore, the shape of the shaping tube section 400 is polygonal, and the transition channel 200 and the crystallizer 300 are used in conjunction with the shape of the shaping tube section 400.

[0073] like Figure 3 As shown, when two adjacent splicing bodies 401 are docked with each other using the slot 402 and the right-angle hook 403, they need to rotate relative to each other by a certain angle. If the shape of the shaping tube section 400 is circular, it is allowed to rotate within the transition channel 200 and the crystallizer 300. That is, the upper shaping tube section 400 cannot rotate relative to the lower shaping tube section 400 and complete the docking. Therefore, the special setting of the shape of the shaping tube section 400 can restrict the shaping tube section 400 through the transition channel 200 and the crystallizer 300, making it unable to rotate. This facilitates the rotation of the upper shaping tube section 400 and the docking of the two adjacent shaping tube sections 400. Of course, the rotation of the upper shaping tube section 400 can be completed by an external robotic arm.

[0074] Furthermore, the guiding structure also includes a power unit 500 for adjusting the moving speed of the shaping tube section 400. The power unit 500 includes a fixed frame 501 fixed relative to the crystallizer 300, a movable frame 502 slidably disposed on the fixed frame 501, and a plurality of rollers 504 arranged on the movable frame 502. The rollers 504 are in driving contact with the outer wall of the shaping tube section 400. The fixed frame 501 and the movable frame 502 are connected by an elastic body 503. The rollers 504 rotate on the movable frame 502, and adjacent rollers 504 are driven by a power wheel 505.

[0075] like Figure 11 and Figure 12 As shown, the rotational power of the drive wheel 505 can be provided by a motor. The drive wheel 505 can drive the two adjacent rollers 504 to rotate. The rollers 504 contact the outer wall of the shaping tube section 400, thereby facilitating the vertical movement of the shaping tube section 400. At the same time, in order to avoid the phenomenon of a gap in power transmission caused by the rollers 504 separating from one shaping tube section 400 before contacting another shaping tube section 400, a configuration of several rollers 504 can be adopted. The elastic body 503 can provide elastic thrust to the moving frame 502, so that the rollers 504 are in close contact with the outer wall of the shaping tube section 400. By adjusting the rotation of the rollers 504, the release speed of the copper rod can be adjusted.

[0076] In addition to using a robotic arm, the disassembly of the shaped tube section 400, optimized from the above implementation, can also be carried out using methods such as... Figure 13The disassembly unit 600 shown in the diagram performs this disassembly. The disassembly unit 600 includes a movable platform 601, a hydraulic cylinder 602 for vertically moving the movable platform 601, a reversing ring 603 rotatably mounted on the movable platform 601, a power disk 604 providing power for the rotation of the reversing ring 603, and several clamping groups for clamping each splice body 401. The number of splice bodies 401 is the same as the number of clamping groups. Each clamping group includes two relatively distributed wheel sets, each wheel set consisting of at least two rotating wheels 605 rotatably mounted on the reversing ring 603. In one wheelset, the straight line containing several wheels 605 is parallel to the straight line containing several wheels 605 in another wheelset. Each wheel 605 has a slidably mounted connecting rod 606, and the wheels 605 and connecting rod 606 are connected by an elastic body 607. A connecting shaft 608 is rotatably mounted on the connecting rod 606. Clamping plates 609 are mounted on the sides of the wheels 605, and the clamping plates 609 rotate relative to each wheel 605 via the connecting shafts 608. When it is necessary to disassemble the shaping tube section 400, the wheels 605 in the clamping group are rotated. Because the wheelset... The structural characteristics of the clamping plate 609 enable it to translate. The two clamping plates 609 move synchronously in opposite directions, and their movement trajectories are circular. When the rotating wheel 605 rotates and drives the clamping plates 609 towards the outer wall of the splicing body 401, the two clamping plates 609 contact the front and rear side walls of the splicing body 401 respectively and clamp the splicing body 401. At this time, due to the restriction of the splicing body 401 on the clamping plates 609, the rotating wheel 605, which continues to rotate, will slide relative to the connecting rod 606. The elastic body 607 undergoes elastic deformation, and the rotating wheel 605... The clamping plate 609 is moved away from the axis of the shaping tube section 400. Using the elastic body 607, the two clamping plates 609 maintain the clamping effect on the splice body 401. As the rotating wheel 605 rotates, the offset distance of the splice body 401 gradually increases. The elastic body 607 pushes the connecting rod 606 to gradually reset. When the connecting rod 606 moves to the initial position on the rotating wheel 605, the clamping plate 609 no longer exerts pressure on the splice body 401. At this time, the splice body 401 can fall naturally and be collected, thus completing the clamping and offset work of the splice body 401.

[0077] It should be noted that when two adjacent shaping tube sections 400 are mutually engaged by relative rotation, the power disc 604 can be used to drive the reversing ring 603 to rotate, causing several clamping groups to drive several splicing bodies 401 to rotate synchronously, so that the splicing body 401 can unlock itself from the shaping tube section 400 above it. Then, the hydraulic cylinder 602 can be used to push the moving table 601 downward to separate the slots 402 and right-angle hooks 403 on the two shaping tube sections 400. After that, the splicing bodies 401 can be separated from each other. Of course, since the shaping tube sections 400 are continuously conveyed, in the initial stage of separation, the hydraulic cylinder 602 can be used to drive the moving table 601 to move, so that the clamping groups and the splicing bodies 401 move downward synchronously.
