Description

Technical Field

[0001] This application relates to the technical field of aluminum ingot smelting, and in particular to a device and process for removing slag from the surface of smelted aluminum ingots. Background Technology

[0002] Aluminum is a metal with low strength and good plasticity. In addition to the use of pure aluminum, an alloying element is usually added to aluminum to improve its strength or overall performance. This is done by adding elements such as magnesium, aluminum-strontium alloys, and aluminum-titanium-boron alloys to change its microstructure and properties, making it suitable for various processed materials or casting parts.

[0003] Currently, in the production of aluminum parts, pre-mixed materials are melted in a centralized melting furnace for approximately one hour, using natural gas as the energy source. The melting temperature is 750°C. The molten metal is then placed in a crucible holding furnace for later casting into blanks. During the melting process, a large amount of slag is generated, requiring regular cleaning. Cleaning the slag from the molten metal typically involves opening the furnace lid, with workers using slag skimmers to carefully remove the slag and pour it into a slag pot. However, opening the furnace exposes the molten metal to air, generating a large amount of metal oxides, further increasing the slag content and complicating the slag removal process. Summary of the Invention

[0004] To facilitate the removal of slag generated during the melting of aluminum ingots in a melting furnace, this application provides a device and process for removing slag from the surface of smelted aluminum ingots.

[0005] Firstly, this application provides a device for removing surface slag from smelted aluminum ingots, which adopts the following technical solution:

[0006] A device for removing surface slag from smelted aluminum ingots includes a frame, a slag pot, and a melting furnace fixedly mounted on the frame. The top wall of the melting furnace is open. A furnace cover is slidably mounted on the frame in a vertical direction. The furnace cover is adapted to the melting furnace. A first driving component is provided on the frame to drive the furnace cover to slide. A slag discharge port is provided on the inner side wall of the melting furnace. The slag discharge port is connected to a guide pipe, and the guide pipe is connected to the slag pot.

[0007] A mounting bracket is slidably mounted on the furnace cover in the vertical direction. A second driving component is provided on the furnace cover to drive the mounting bracket to slide. The mounting bracket is used to slide into the melting furnace. A slag baffle is fixedly mounted on the mounting bracket. A rotating frame is also rotatably mounted on the mounting bracket. A first driving component is provided on the furnace cover to drive the rotating frame to rotate.

[0008] A slag-scraping hopper is rotatably mounted on the rotating frame, and a second driving component is provided on the rotating frame to drive the slag-scraping hopper to rotate. The slag-scraping hopper is used to pour slag into the slag discharge port, and a first sealing component is provided on the melting furnace to seal the slag discharge port.

[0009] By adopting the above technical solution, when cleaning the slag in the melting furnace, the second driving component drives the mounting frame to slide down into the melting furnace, inserting the slag baffle into the molten metal, with the top of the baffle outside the molten metal and the bottom of the slag hopper inside the molten metal. The first driving component drives the rotating frame to rotate, thereby loading the slag into the slag hopper. Then, the mounting frame is driven to rise a certain distance, positioning the slag hopper at the slag discharge port. The first sealing component is opened, and the second driving component drives the slag hopper to rotate, pouring the slag in the slag hopper into the slag discharge port. The slag then enters the slag pot through the guide pipe, completing the cleaning of the slag in the melting furnace. During the cleaning of the slag in the melting furnace, the melting furnace is in a closed state, and the molten metal is less likely to come into contact with air and produce metal oxides, making the slag removal work more convenient.

[0010] Optionally, the first sealing assembly includes a first sealing plate and a first motor. The first sealing plate is rotatably disposed inside the melting furnace and is adapted to the slag discharge port. The first motor is used to drive the first sealing plate to rotate.

[0011] By adopting the above technical solution, the first sealing plate is rotated by the first motor, so that the first sealing plate is pressed against the slag discharge port, thereby achieving the sealing of the slag discharge port.

[0012] Optionally, the slag discharge port is inclined downwards in the direction away from the interior of the melting furnace, and the feed pipe gradually inclines downwards in the direction from the melting furnace toward the slag pot.

[0013] By adopting the above technical solution, the scum can easily enter the scum tank through the guide pipe after entering the scum discharge port, thus making it less likely to accumulate at the scum discharge port.

[0014] Optionally, the rotation axis of the first sealing plate is horizontal, and the connection end of the first sealing plate with the melting furnace is close to the lower wall of the slag discharge port. A guide plate is fixedly provided at the end of the first sealing plate away from the interior of the melting furnace, and baffles are fixedly provided on both sides of the guide plate.

[0015] By adopting the above technical solution, the slag discharge port opens after the first sealing plate is flipped at a certain angle. Then, the slag is simply poured onto the first sealing plate, and the slag is guided into the slag discharge port by the guide plate. The two baffles prevent the slag from falling back onto the molten liquid, making it more convenient to pour the slag into the slag discharge port from the slag hopper.

[0016] Optionally, the bottom wall of the furnace cover is provided with a receiving groove for the mounting bracket, slag hopper and slag baffle to slide into, and the furnace cover is provided with a second sealing component for closing the receiving groove.

[0017] By adopting the above technical solution, when the slag removal bucket is cleaning low slag, a certain amount of slag will adhere to the bottom of the slag removal bucket. When slag removal is not required, the mounting frame, slag removal bucket and slag baffle are all located in the receiving tank, and the receiving tank is sealed by the second sealing component, thereby effectively preventing dirt on the slag removal bucket from falling into the molten metal.

[0018] Optionally, the second sealing assembly includes a second sealing plate and a third driving member. The side wall of the receiving groove has a placement groove communicating with the receiving groove. The second sealing plate is slidably disposed within the placement groove and can slide into the receiving groove. The third driving member is used to drive the second sealing plate to slide.

[0019] By adopting the above technical solution, the second sealing plate is slid by the third driving component, so that the second sealing plate slides into the receiving groove, thereby sealing the receiving groove.

[0020] Optionally, the first driving assembly includes a rotating rod, a telescopic rod, and a second motor. The rotating rod is rotatably mounted on the furnace cover, and the axial direction of the rotating rod is vertical. The rotating rod extends into the receiving groove, and a sliding groove is formed at the bottom end of the rotating rod along its length. The telescopic rod is slidably mounted in the sliding groove, and the telescopic rod is coaxially and fixedly connected to the rotating shaft of the rotating frame. The second motor is used to drive the rotating rod to rotate.

[0021] By adopting the above technical solution, during the sliding process of the mounting frame, the telescopic rod slides inside the rotating rod, and the second motor drives the rotating rod to rotate, which in turn drives the telescopic rod to rotate, thereby driving the rotating frame to rotate.

[0022] Optionally, the second drive assembly includes a winding wheel, a pull rope, and a third motor. The winding wheel is rotatably mounted on the top wall of the furnace cover. The pull rope is wound around the winding wheel. The top wall of the rotating rod has a first through hole communicating with the slide groove. The telescopic rod is hollow. The pull rope passes through the through hole and is inserted into the telescopic rod. The side wall of the telescopic rod has a second through hole communicating with the interior of the telescopic rod. The pull rope passes through the second through hole and is fixedly connected to the slag hopper. The third motor is used to drive the winding wheel to rotate.

[0023] By adopting the above technical solution, when the mounting frame is raised and lowered, the winding wheel is driven to rotate by the third motor, which cooperates with the raising and lowering of the mounting frame. When it is necessary to drive the slag bucket to rotate, the winding wheel is driven to rotate, and the slag bucket is driven to rotate by the pull rope.

[0024] Secondly, this application provides a process for a device for removing surface slag from smelted aluminum ingots, employing the following technical solution:

[0025] A process for a device for removing surface slag from smelted aluminum ingots includes the following steps:

[0026] S1. When cleaning the slag in the melting furnace, the second driving component drives the mounting frame to slide into the melting furnace, so that the slag baffle is inserted into the molten liquid, and the top of the slag baffle is outside the molten liquid, while the bottom of the slag hopper is inside the molten liquid.

[0027] S2. Drive the rotating frame to rotate, thereby loading the scum into the scum hopper;

[0028] S3. Then drive the mounting frame to rise a certain distance so that the slag hopper is located at the slag discharge port.

[0029] S4. Open the slag discharge port and drive the slag scraper to rotate, pouring the slag in the slag scraper into the slag discharge port. The slag then enters the slag pot through the feed pipe, completing the cleaning of the slag in the melting furnace.

[0030] In summary, this application includes at least one of the following beneficial technical effects:

[0031] 1. When cleaning the slag in the melting furnace, the second drive component drives the mounting frame to slide down into the melting furnace, inserting the slag baffle into the molten metal, with the top of the baffle outside the molten metal and the bottom of the slag hopper inside the molten metal. The first drive component drives the rotating frame to rotate, thereby loading the slag into the slag hopper. Then, the mounting frame is driven to rise a certain distance, positioning the slag hopper at the slag discharge port. The first sealing component is opened, and the second drive component drives the slag hopper to rotate, pouring the slag in the slag hopper into the slag discharge port. The slag enters the slag pot through the guide pipe, completing the cleaning of the slag in the melting furnace. During the cleaning of the slag in the melting furnace, the melting furnace is in a closed state, and the molten metal is less likely to come into contact with air and produce metal oxides, making the slag removal work more convenient.

[0032] 2. When cleaning low-level slag, a certain amount of slag will adhere to the bottom of the slag bucket. When slag cleaning is not required, the mounting frame, slag bucket, and slag baffle are all located in the receiving tank, and the receiving tank is sealed by the second sealing component, thereby effectively preventing dirt on the slag bucket from falling into the molten metal.

[0052] S1. When cleaning the slag in the melting furnace 3, the second sealing plate 42 is slid by the servo cylinder to open the receiving groove 41.

The telescopic rod 451 slides in the rotating rod 45 to insert the slag baffle 51 into the melt, and the top of the slag baffle 51 is located outside the melt, while the bottom of the slag hopper 521 is located inside the melt.

[0053] S2. The second motor 46 drives the rotating rod 45 to rotate, the rotating rod 45 drives the telescopic rod 451 to rotate, and then drives the rotating frame 52 to rotate, thereby loading the scum into the scum hopper 521.

[0054] S3. Then drive the mounting frame 5 to rise a certain distance so that the slag hopper 521 is located at the slag discharge port 32.

[0055] S4. The first motor 35 drives the first sealing plate 34 to rotate 45°, opening the slag discharge port 32.
