Description

Technical Field

[0001] This application relates to the field of aluminum alloy casting, and in particular to an integrated device and method for refining, degassing, and slag removal. Background Technology

[0002] In aluminum alloy casting production, the purity of the melt is crucial to determining the performance and quality of the final casting. Refining (removing inclusions), degassing (primarily removing hydrogen), and slag removal (removing surface slag) are the three core processes ensuring melt purity. Currently, the industry commonly uses refining and degassing as two independent but sequential steps. Refining and degassing are typically accomplished using rotary jetting or flux powder spraying devices. These devices introduce inert gases (such as argon) or refining agent powder into the depths of the molten pool, where the flotation effect of bubbles carries away hydrogen and inclusions, causing them to float to the surface of the melt and form slag. After the refining and degassing process is completed and the melt has settled, operators manually remove the slag layer accumulated on the surface of the melt using handheld slag rakes or similar tools. However, traditional refining degassing and slag removal operations are characterized by fragmented and independent processes, cumbersome and time-consuming procedures, numerous blind spots in refining degassing and slag removal, high labor intensity for operators, significant occupational health risks, and work quality that heavily relies on individual physical strength and experience. Summary of the Invention

[0004] To achieve the above objectives, this invention proposes an integrated refining, degassing, and slag-removing device, comprising a worktable, an X-axis translation module, a Y-axis translation module, a Z-axis translation module, a transition pipe, a refining degassing pipe, a refining powder tank, and a slag-removing rake; the X-axis translation module extends horizontally, the Y-axis translation module extends horizontally and is perpendicular to the X-axis translation module, and the Z-axis translation module extends vertically; the Y-axis translation module is located on the top of the worktable, and is used to mount the Z-axis translation module and drive the Z-axis translation module along... The Y-axis performs linear reciprocating motion. The Z-axis translation module is used to install the X-axis translation module and drive the X-axis translation module to perform linear reciprocating motion along the Z-axis. The X-axis translation module is used to install the transition tube and drive the transition tube to perform linear reciprocating motion along the X-axis. The transition tube is a hollow tubular structure. The refining degassing pipe or the slag rake can be detachably connected to one end of the transition tube. The refining powder tank has an air inlet and an air outlet. The air outlet is used to connect to the other end of the transition tube, so that the refining powder tank is connected to the refining degassing pipe through the transition tube.

[0005] In some embodiments of the present invention, a host computer and a controller are also included. The host computer is used to set the motion trajectory of the refining degassing pipe in the refining degassing process or to set the motion trajectory of the slag rake in the slag removal process. The controller parses the corresponding motion trajectory into motion control commands for the X-axis translation module, Y-axis translation module, and Z-axis translation module and sends them out to drive the X-axis translation module, Y-axis translation module, and Z-axis translation module to perform preset motions.

[0006] In some embodiments of the present invention, a feedback module is also included, which transmits the actual position data of the X-axis translation module, Y-axis translation module and Z-axis translation module in real time, and the controller compares the target position with the actual position to perform closed-loop correction.

[0007] In some embodiments of the present invention, the Y-axis translation module includes a first slide rail, a first base plate, a first lead screw, and a first drive motor; The first slide rail is horizontally set on the workbench, the bottom of the first base plate is slidably connected to the first slide rail, the first lead screw is set parallel to the first slide rail and connected to the first base plate through the lead screw nut and nut seat, and the first drive motor is used to drive the first lead screw to rotate.

[0008] In some embodiments of the present invention, the Z-axis translation module includes a second slide rail, a second base plate, a second lead screw, and a second drive motor; The second slide rail is vertically mounted on the first base plate, and the second base plate and the second slide rail are slidably connected along the height direction. The second lead screw is parallel to the second slide rail and connected to the second base plate through the lead screw nut and nut seat. The second drive motor is used to drive the second lead screw to rotate.

[0009] In some embodiments of the present invention, the X-axis translation module includes a third slide rail, a third base plate, a third lead screw, and a third drive motor; The third slide rail is horizontally mounted on the second base plate, and the third base plate and the third slide rail are slidably connected in the horizontal direction. The third lead screw is arranged parallel to the third slide rail and connected to the third base plate through a lead screw nut and a nut seat. The transition tube is installed on the third base plate, and the third drive motor is used to drive the third lead screw to rotate.

[0010] In some embodiments of the present invention, a connector is also included, which is installed at one end of the transition tube, and the refining degassing tube or the slag rake is detachably connected to the transition tube via the connector.

[0011] In some embodiments of the present invention, the air outlet and the transition pipe are connected by a flexible connecting air pipe.

[0012] In some embodiments of the present invention, the bottom of the workbench is provided with casters with brakes.

[0013] To achieve the above objectives, the present invention also proposes a method for refining, degassing, and slag removal using the aforementioned integrated refining, degassing, and slag removal device, characterized by comprising the following steps: (1) Establish the spatial coordinate system of the inner cavity of the molten metal furnace; (2) Install the refining degassing pipe on the transition pipe and connect the refining powder tank to the refining degassing pipe through the transition pipe; (3) Set the motion trajectory parameters of the refining degassing operation according to the spatial coordinate system of the inner cavity of the molten metal furnace, and use the X-axis translation module, Y-axis translation module and Z-axis translation module to coordinately adjust the position of the refining degassing pipe to complete the refining degassing operation; (4) Remove the refining degassing pipe from the transition pipe and replace it with a slag rake. Set the motion trajectory parameters of the slag removal operation according to the spatial coordinate system of the inner cavity of the molten metal furnace, and use the X-axis translation module, Y-axis translation module and Z-axis translation module to coordinately adjust the position of the slag rake to complete the slag removal operation.

[0014] This application provides an integrated refining degassing and slag removal device and method that highly integrates refining degassing and slag removal functions for continuous and coordinated operation. This integrated device combines the two most critical processes into a single workbench and motion mechanism, eliminating the need for separate refining degassing and slag removal processes using different devices / methods. This significantly shortens the operation time for refining degassing and slag removal, and reduces heat loss. Furthermore, the replaceable workpiece design allows for flexible function switching, avoiding the cost of purchasing two large dedicated machines. It is particularly suitable for production scenarios with multiple product varieties, small batches, or limited workshop space, resulting in extremely high equipment utilization. Secondly, utilizing X... The coordinated operation of the Z-axis translation module, Y-axis translation module, and Z-axis translation module enables the equipment to move freely in multiple degrees of freedom, including vertical (Z-axis), horizontal (Y-axis), and vertical (X-axis). During refining, it can achieve "S"-shaped or spiral scanning movement of the refining degassing pipe, ensuring no blind spots in refining degassing. During slag removal, it can precisely control the slag removal path, improving slag removal cleanliness and reducing metal carry-out loss. In addition, the most arduous and high-temperature refining degassing pipe holding and slag removal actions are handled by the machine. The operator only needs to change the working end and observe from a safe distance, which greatly reduces labor intensity and occupational health risks, and frees the quality of operation from absolute dependence on personal physical strength and experience.

All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0018] In the following description, when referring to the accompanying drawings, the same numbers in different drawings denote the same or similar elements unless otherwise indicated.

Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

The character " / " generally indicates that the preceding and following related objects are in an "or" relationship.

[0020] Currently, refining and degassing are typically accomplished using rotary jetting or flux powder spraying devices. These devices introduce inert gases (such as argon) or refining agent powders into the depths of the molten pool, where the flotation effect of bubbles carries away hydrogen and inclusions, causing them to float to the surface of the melt and form slag. After the refining and degassing process is completed and the melt has been allowed to settle, operators manually remove the slag layer accumulated on the surface of the melt using handheld slag rakes or similar tools. This traditional separate operation mode has revealed many inherent defects in practical applications, becoming a bottleneck restricting further improvements in production efficiency and quality: 1) Discrete processes and low efficiency: Refining and slag removal require switching equipment and step-by-step operations, resulting in a lengthy melt processing cycle. During the process transition intervals, the melt is exposed to air for extended periods, increasing heat loss and partially offsetting the effects of the previous refining process due to secondary gas absorption and oxidation, creating a negative cycle of "processing-contamination." 2) Poor manual slag removal efficiency and high losses: Slag removal operations are highly dependent on the experience and skills of the operators. For melts with high surface tension and viscous slag, such as high-silicon aluminum alloys, manual slag removal is difficult to completely remove all slag, and it is very easy to remove a large amount of valuable pure metal liquid along with the slag during the skimming process, resulting in a decrease in raw material utilization. The thoroughness and consistency of slag removal cannot be guaranteed. 3) Low degree of automation and harsh environment: Manual slag removal is labor-intensive, the working environment is high-temperature and dangerous, and it is not conducive to the standardized collection of production process data and the closed-loop control of process stability, making it difficult to meet the needs of modern and intelligent foundry workshops.

[0021] To achieve high melt purity and efficient refining, degassing, and slag removal in aluminum alloy casting production, and to address the problems of traditional refining, degassing, and slag removal processes being fragmented and independent, cumbersome and time-consuming, having many dead zones, high labor intensity for operators, significant occupational health risks, and work quality heavily reliant on individual physical strength and experience, current methods, such as blowing air to drive slag towards the slag removal port and then using a robotic arm to remove it, have been proposed. While this method can reduce dead zones and improve slag removal efficiency, air blowing is only used to drive slag, and refining and degassing still need to be completed by other equipment. In addition, although ultrasonic, rotary jet blowing, and vacuum degassing technologies have been proposed, these methods focus on the extreme optimization of refining and degassing and do not involve the integration or innovation of slag removal equipment, and slag removal still relies on subsequent independent processes.

[0022] Therefore, this invention proposes an integrated refining degassing and slag removal device and method that highly integrates refining degassing and slag removal functions for continuous and coordinated operation. This addresses the problems of traditional refining degassing and slag removal operations, which involve fragmented and independent processes, cumbersome and time-consuming procedures, numerous blind spots, high labor intensity for operators, significant occupational health risks, and work quality heavily reliant on individual physical strength and experience. It also solves the efficiency losses, quality fluctuations, and metal losses caused by process fragmentation, achieving the integration of refining degassing and slag removal functions, reducing labor intensity, and stabilizing operation. Furthermore, this integrated refining degassing and slag removal device can also be used in refining degassing and slag removal scenarios for other metals besides aluminum alloy casting.

[0023] The integrated refining, degassing, and slag removal device and method provided in the embodiments of this application are described below with reference to the accompanying drawings.

[0024] This application discloses an integrated refining, degassing, and slag removal device. For example... Figures 1-3 As shown, the integrated refining, degassing, and slag removal device includes a workbench 1, an X-axis translation module, a Y-axis translation module, a Z-axis translation module, a transition pipe 2, a refining degassing pipe 3, a refining powder tank 4, and a slag removal rake 5; the X-axis translation module extends horizontally, the Y-axis translation module extends horizontally and is perpendicular to the X-axis translation module, and the Z-axis translation module extends vertically.

[0025] The Y-axis translation module is located on the top of the worktable 1. The Y-axis translation module is used to install the Z-axis translation module and drive the Z-axis translation module to perform linear reciprocating motion along the Y-axis. The Z-axis translation module is used to install the X-axis translation module and drive the X-axis translation module to perform linear reciprocating motion along the Z-axis. The X-axis translation module is used to install the transition tube 2 and drive the transition tube 2 to perform linear reciprocating motion along the X-axis.

[0026] The transition pipe 2 is a hollow tubular structure. The refining degassing pipe 3 or the slag rake 5 can be detachably connected to one end of the transition pipe 2. The refining powder tank 4 has an air inlet 401 and an air outlet 402. The air outlet 402 is used to connect to the other end of the transition pipe 2, so that the refining powder tank 4 is connected to the refining degassing pipe 3 through the transition pipe 2.

[0027] In this invention, when aluminum alloy melt is smelted inside a metal melt furnace, the refining and degassing pipe 3 is first installed on the transition pipe 2 during the refining and degassing stage, based on the spatial coordinates of the furnace's internal cavity. The refining powder tank 4 is then connected to the refining and degassing pipe 3 via the transition pipe 2. The position of the refining and degassing pipe 3 is adjusted collaboratively using the X-axis translation module, Y-axis translation module, and Z-axis translation module. Simultaneously, inert gas (such as argon) is blown into the refining powder tank 4 from the inlet 401, allowing the inert gas to react with the refined powder. The refining agent powder is mixed, and then the inert gas and refining agent powder are injected into the melt from the end of the refining degassing pipe 3 after passing through the transition pipe 2 and the refining degassing pipe 3. This ensures that the refining degassing of the melt is uniform and without dead angles. Then, in the slag removal stage, the refining degassing pipe 3 is removed from the transition pipe 2 and replaced with a slag rake 5. The position of the slag rake 5 is adjusted by the X-axis translation module, Y-axis translation module and Z-axis translation module to remove the slag layer accumulated on the surface of the melt, thus completing the slag removal work.

[0028] This invention utilizes an integrated refining, degassing, and slag removal device. By integrating the two most critical processes into a single workbench 1 and motion mechanism, it eliminates the need for separate refining, degassing, and slag removal processes using different devices / methods, significantly shortening the operation time and reducing heat loss. Simultaneously, the design with interchangeable working ends (refining degassing pipe 3 / slag removal rake 5) allows for flexible function switching, avoiding the cost of purchasing two large, dedicated machines. It is particularly suitable for production scenarios with multiple varieties, small batches, or limited workshop space, resulting in extremely high equipment utilization. Furthermore, it utilizes X-axis translation modules, Y-axis translation modules, and Z-axis... The collaborative translation module enables the equipment to move freely in multiple degrees of freedom, including vertical (Z-axis), horizontal (Y-axis), and vertical (X-axis) directions. During refining, it can achieve "S"-shaped or spiral scanning movement of the refining degassing pipe 3, ensuring no blind spots in refining degassing. During slag removal, it can precisely control the slag removal path, improving slag removal cleanliness and reducing metal carry-out loss. In addition, the most arduous and high-temperature refining degassing pipe 3 holding and slag removal actions are handled by the machine. The operator only needs to change the working end and observe from a safe distance, which greatly reduces labor intensity and occupational health risks, and frees the quality of operation from absolute dependence on personal physical strength and experience.

[0029] In some embodiments of the present invention, the refining degassing and slag removal modules are separated, which is a modular design that facilitates the upgrading of the refining degassing and slag removal modules, and allows for the technical upgrading of any module individually in the future.

[0030] In some embodiments of the present invention, for example, the refining degassing pipe 3 can be upgraded to a refining degassing pipe 3 with a rotating nozzle, or the slag rake 5 can be upgraded to a slag rake 5 with a smart slag rake head with visual recognition, which not only improves the applicability of the equipment, but also extends the overall technical life cycle of the equipment.

[0031] In some embodiments of the present invention, the integrated refining, degassing, and slag removal device further includes a host computer and a controller. The host computer is used to set the movement trajectory of the refining and degassing pipe 3 in the refining and degassing process or to set the movement trajectory of the slag removal rake 5 in the slag removal process. The controller parses the corresponding movement trajectory into motion control commands for the X-axis translation module, Y-axis translation module, and Z-axis translation module and sends them out to drive the X-axis translation module, Y-axis translation module, and Z-axis translation module to perform preset movements.

[0032] In this embodiment, a spatial coordinate system is established for the inner cavity of the molten metal furnace. After the host computer sets the trajectory, the controller parses it into motion control commands for the X-axis translation module, Y-axis translation module, and Z-axis translation module and sends them out. This drives the X-axis translation module, Y-axis translation module, and Z-axis translation module to execute preset movements, thereby causing the refining degassing pipe 3 or the slag rake 5 to move according to their respective set motion trajectories, so as to automatically complete the refining degassing operation and the slag removal operation.

[0033] In some embodiments of the present invention, the integrated refining, degassing, and slag removal device further includes a feedback module, which transmits the actual position data of the X-axis translation module, Y-axis translation module, and Z-axis translation module in real time. The controller compares the target position with the actual position to perform closed-loop correction to ensure motion accuracy.

[0034] In some embodiments of the present invention, such as Figure 1 and Figure 2 As shown, the Y-axis translation module includes a first slide rail 6, a first base plate 7, a first lead screw 8, and a first drive motor 9. The first slide rail 6 is horizontally set on the worktable 1. The bottom of the first base plate 7 is slidably connected to the first slide rail 6. The first lead screw 8 is set parallel to the first slide rail 6 and connected to the first base plate 7 through a lead screw nut and a nut seat. The first drive motor 9 is used to drive the first lead screw 8 to rotate.

[0035] In this embodiment, the first base plate 7 is slidably connected to the worktable 1 via the first slide rail 6. When the first drive motor 9 is started, the output shaft of the first drive motor 9 rotates, thereby driving the first lead screw 8 to rotate. The first lead screw 8 is connected to the first base plate 7 via a nut and a nut seat, thereby driving the first base plate 7 to move in the length direction of the first slide rail 6. By using the forward or reverse rotation of the first drive motor 9, the position of the first base plate 7 in the length direction of the first slide rail 6 can be adjusted, thereby causing the transition tube 2 to move in the Y-axis direction. When the first drive motor 9 stops, the first base plate 7 is locked in a specific position on the first slide rail 6.

[0036] In some embodiments of the present invention, the first drive motor 9 is fixed to the upper surface of the worktable 1 by the first fixing plate 10, and the output shaft of the first drive motor 9 is coaxially connected to the first lead screw 8.

[0037] In some embodiments of the present invention, multiple first slide rails 6 may be provided, such as two first slide rails 6, which are parallel and spaced apart, so that the first seat plate 7 can slide stably on the first slide rails 6.

[0038] In some embodiments of the present invention, such as Figure 1 and Figure 2 As shown, the Z-axis translation module includes a second slide rail 11, a second base plate 12, a second lead screw 13, and a second drive motor 14. The second slide rail 11 is vertically mounted on the first base plate 7. The second base plate 12 is slidably connected to the second slide rail 11 along the height direction. The second lead screw 13 is parallel to the second slide rail 11 and connected to the second base plate 12 through a lead screw nut and a nut seat. The second drive motor 14 is used to drive the second lead screw 13 to rotate.

[0039] In this embodiment, the second seat plate 12 is slidably connected to the first seat plate 7 in the vertical direction via the second slide rail 11. When the second drive motor 14 is started, the output shaft of the second drive motor 14 rotates, thereby driving the second lead screw 13 to rotate. By connecting the second lead screw 13 and the second seat plate 12 through a nut and a nut seat, the second seat plate 12 is driven to move in the height direction of the second slide rail 11, that is, the height of the second seat plate 12 relative to the first seat plate 7 changes. By using the forward or reverse rotation of the second drive motor 14, the position of the second seat plate 12 in the height direction of the second slide rail 11 is adjusted, thereby causing the transition tube 2 to move in the Z-axis direction. When the second drive motor 14 stops, the second seat plate 12 is locked at a specific height on the second slide rail 11.

[0040] In some embodiments of the present invention, four second slide rails 11 are provided. The four second slide rails 11 are vertically fixed near the four corners of the upper surface of the first base plate 7. The second base plate 12 is horizontally arranged. The four second slide rails 11 penetrate the second base plate 12 and are slidably connected to the second base plate 12. Through the four second slide rails 11, the second base plate 12 can slide in its height direction, and the second base plate 12 can be kept in a horizontal position.

[0041] In some embodiments of the present invention, the second drive motor 14 is mounted above the first base plate 7 via two parallel and spaced vertical fixing rods 15. The second drive motor 14 is connected to the top of the fixing rods 15 via a second fixing plate 16 and fixing bolts 17. The output shaft of the second drive motor 14 is vertically downward and coaxially fixed with the second lead screw 13. The second lead screw 13 passes downward through the second base plate 12 and is connected to the second base plate 12 via a lead screw nut and a nut seat.

[0042] Furthermore, a lead screw end seat 18 can be fixed on the upper surface of the first seat plate 7 at the position corresponding to the second lead screw 13 to stabilize the bottom end of the second lead screw 13, and the second lead screw 13 can rotate relative to the lead screw end seat 18.

[0043] Furthermore, the upper surface of the lead screw end seat 18 is provided with a limit switch for the second drive motor 14. When the second seat plate 12 presses the limit switch, the second drive motor 14 is de-energized to achieve shutdown protection.

[0044] In some embodiments of the present invention, such as Figure 1 and Figure 2 As shown, the X-axis translation module includes a third slide rail 19, a third base plate 20, a third lead screw 21, and a third drive motor 22. The third slide rail 19 is horizontally mounted on the second base plate 12. The third base plate 20 is slidably connected to the third slide rail 19 in the horizontal direction. The third lead screw 21 is arranged parallel to the third slide rail 19 and connected to the third base plate 20 through a lead screw nut and a nut seat. The transition tube 2 is installed on the third base plate 20. The third drive motor 22 is used to drive the third lead screw 21 to rotate.

[0045] In this embodiment, the third seat plate 20 is slidably connected to the second seat plate 12 in the horizontal direction via the third slide rail 19. When the third drive motor 22 is started, the output shaft of the third drive motor 22 rotates, thereby driving the third lead screw 21 to rotate. The third lead screw 21 is connected to the third seat plate 20 via a nut and a nut seat, thereby driving the third seat plate 20 to move in the length direction of the third slide rail 19. By using the forward or reverse rotation of the third drive motor 22, the position of the third seat plate 20 in the length direction of the third slide rail 19 can be adjusted, thereby causing the transition tube 2 to move in the X-axis direction. When the third drive motor 22 stops, the third seat plate 20 is locked in a specific position on the third slide rail 19.

[0046] In some embodiments of the present invention, two third slide rails 19 are provided. The two third slide rails 19 are mounted on the second base plate 12 in parallel and spaced apart by columns or plates, and the two third slide rails 19 extend from one edge of the second base plate 12. The two third slide rails 19 penetrate from both ends of the third base plate 20. The two third slide rails 19 provide stable support for the third base plate 20 and allow the third base plate 20 to slide on the third slide rails 19. The third drive motor 22 is fixed to the upper surface of the second base plate 12 by the third fixing plate 23. The output shaft of the third drive motor 22 extends horizontally outside the second base plate 12 and is coaxially fixed with the third lead screw 21. The third lead screw 21 passes horizontally through the third base plate 20 and is connected to the third base plate 20 through the lead screw nut and nut seat.

[0047] In some embodiments of the present invention, a fixed seat 24 is provided on the top of the third seat plate 20, and a fixed block 25 is fixed on the fixed seat 24. The transition tube 2 is installed on the third seat plate 20 through the fixed block 25 and the fixed seat 24, and the transition tube 2 is parallel to the third slide rail 19.

[0048] Furthermore, the mounting base 24 is detachably connected to the third mounting plate 20 by bolts.

[0049] In some embodiments of the present invention, the first drive motor 9, the second drive motor 14 and the third drive motor 22 are respectively connected to the controller via drivers. After the host computer sets the trajectory, the controller parses it into motion commands for the first drive motor 9, the second drive motor 14 and the third drive motor 22, and drives the first base plate 7, the second base plate 12 and the third base plate 20 to move via their respective drivers. The feedback module transmits position data back in real time, and the controller performs closed-loop correction to ensure motion accuracy.

[0050] In some embodiments of the present invention, such as Figure 1 As shown, the integrated refining degassing and slag removal device also includes a connector 26, which is installed at one end of the transition pipe 2. The refining degassing pipe 3 or the slag removal rake 5 is detachably connected to the transition pipe 2 through the connector 26.

[0051] In some embodiments of the present invention, the connector 26 includes, but is not limited to, threaded pipe fittings or clamp-type pipe fittings, which not only ensures the reliability and stability of the connection, but also facilitates quick replacement of the working end, enabling rapid disassembly and repeated assembly of different working ends.

[0052] In some embodiments of the present invention, such as Figure 1 As shown, the air outlet 402 is connected to the transition pipe 2 via a flexible connecting air pipe 27.

[0053] In some embodiments of the present invention, the flexible connecting gas pipe 27 includes, but is not limited to, hoses or corrugated pipes, so that the X-axis translation module, Y-axis translation module, and Z-axis translation module can move the transition pipe 2 and the refining degassing pipe 3 without damage while the refining powder tank 4 remains stationary.

[0054] In some embodiments of the present invention, such as Figure 1 As shown, the bottom of the workbench 1 is equipped with universal casters 28 with brakes.

[0055] In this embodiment, the device can be easily moved by the casters 28. In addition, the casters 28 have a locking function to ensure that the device is stationary when it is working.

[0056] In some embodiments of the present invention, the transition pipe 2 and the refining degassing pipe 3 may include, but are not limited to, metal pipes such as steel pipes, to ensure that the inert gas and refining agent powder are sprayed into the interior of the melt.

[0057] Furthermore, such as Figure 3 As shown, the end of the refining degassing pipe 3 used for injection is bent to inject inert gas and refining agent powder into the melt. The bending angle can be designed as needed.

[0058] This embodiment also proposes a method for refining, degassing, and slag removal using the above-mentioned integrated refining, degassing, and slag removal device, which includes the following steps: (1) Establish the spatial coordinate system of the inner cavity of the metal molten furnace.

[0059] (2) Install the refining degassing pipe 3 on the transition pipe 2, and connect the refining powder tank 4 to the refining degassing pipe 3 through the transition pipe 2.

[0060] (3) Based on the spatial coordinate system of the inner cavity of the molten metal furnace, set the motion trajectory parameters for the refining and degassing operation, and use the X-axis translation module, Y-axis translation module and Z-axis translation module to coordinately adjust the position of the refining and degassing pipe 3 to complete the refining and degassing operation.

[0061] (4) Remove the refining degassing pipe 3 from the transition pipe 2 and replace it with the slag rake 5. Based on the spatial coordinate system of the inner cavity of the molten metal furnace, set the motion trajectory parameters for the slag removal operation. Use the X-axis translation module, Y-axis translation module and Z-axis translation module to coordinate and adjust the position of the slag rake 5 to complete the slag removal work.

[0062] The refining, degassing, and slag removal method of this application will be further described below with reference to specific embodiments.

[0063] Example 1 In a certain aluminum alloy casting production process, the spatial coordinate system of the inner cavity of the aluminum alloy melting furnace is as follows: Figure 4 As shown, the x-axis represents left and right, the y-axis represents front and back, and the z-axis represents up and down.

[0064] To simplify the description, assume that the refining degassing pipe and the slag scraper have no shape at the point where they contact the melt (defined as the front end). The refining degassing pipe is installed on the equipment. The motion trajectory parameters for the refining degassing and slag scraping operations are set, with a moving speed of 10 mm / s and a starting point of (0, 0, 500). The refining degassing pipe and slag scraper descend to 100 mm below the melt surface, i.e., set to (0, 0, 400), and then move to the right, reaching (1100, 0, 400). The front end of the refining degassing pipe and slag scraper touches the inclined surface of the furnace opening. At this point, while the front end of the refining degassing pipe and slag scraper moves to the right, it also needs to move upwards, sequentially passing through points (1110, 0, 410), (1120, 0, 420), ..., (1200, 0, 500), etc. Then, the front end is set to move forward 100 mm to point (1200, 100, 500), and then moves to the left, repeating this cycle until the entire furnace cavity is traversed. During this process, when refining and degassing is performed, argon gas enters the refining powder tank through the inlet. Under the action of argon gas and gravity, the refining agent powder in the refining powder tank is carried into the flexible connecting gas pipe through the outlet of the refining powder tank, and then enters the transition pipe and the refining and degassing pipe, and is sent into the aluminum alloy melt. After the refining and degassing is completed, the refining and degassing pipe is replaced with a slag rake through the connector, the equipment is started, and then the equipment automatically completes the slag removal operation according to the set path trajectory.

[0065] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
