Description

Technical Field

[0001] The utility model relates to the technical field of metal casting forming devices, in particular to an environment-friendly aluminum ingot continuous casting and one-time forming device. Background Technique

[0002] In the aluminum ingot casting process, molten aluminum is injected into a mold. After cooling into a billet and taken out, the injection process is the key step for the quality of the product. The casting process is a physical process of crystallizing liquid aluminum into solid aluminum.

[0003] In the traditional casting mode, it is difficult to maintain the consistency of aluminum ingots. During the process of casting and forming aluminum ingots, it is necessary to transport the materials inside the shell to the inside of the casting box for aluminum ingot forming. Since there is only one set of casting boxes arranged on one side of the shell, a single production of aluminum ingots is formed, and continuous forming operation of aluminum ingots cannot be realized, reducing the production efficiency of aluminum ingots.

[0004] Moreover, the existing casting is directly carried out from a single casting nozzle. It not only has low casting efficiency, but also causes splashing during the casting process, posing a safety hazard. It is not easy to control the pouring speed and flow rate of molten aluminum, affecting the forming quality of the mold. Later, the surface treatment of the formed aluminum ingots is also required. The production process is more, the labor intensity is high, and the production efficiency is low.

[0005] The aluminum ingot casting device of the utility model effectively improves the working efficiency of aluminum ingot casting, surface grinding, flue gas collection, demoulding, etc., improves the quality of the product, enables it to fully meet the requirements of steelmaking production for the quality of aluminum ingots, has a simple structure, is easy and quick to operate, does not occupy much space, is easy to move, can effectively reduce the labor intensity of workers, and improve the working environment.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] See the attached Figures 1-4 ;

[0026] An environmentally friendly aluminum ingot continuous casting and one-time forming device includes a base 1. A casting roller 5 is erected on the base 1. Casting discharge components are distributed on the circumferential surface of the casting roller 5. Aluminum ladles 3 are respectively erected at both ends of the casting roller 5 through aluminum ladle supports 2. Casting pipes 4 leading to the inside of the casting roller are respectively arranged at the inner bottom ends of the aluminum ladles 3. A mold conveyor belt 13 is erected on the base on the discharge side of the casting roller. Aluminum ingot grooves 14 are evenly distributed at intervals on the mold conveyor belt 13. A flue gas collection box 15 is arranged on the top of the mold conveyor belt 13. A circulation fan 16 is arranged inside the flue gas collection box, and a flue gas purifier 17 is arranged on the outer wall. A scraping mechanism, a cooling mechanism, and a grinding mechanism are successively erected at the bottom of the flue gas collection box 15 from the feed end to the discharge end of the mold conveyor belt. A ingot receiving conveyor belt 23 is erected at the end of the discharge end of the mold conveyor belt 13. The rotation of the casting roller is driven by a driving wheel (8) and a motor (9) at the same time, and the rotating casting roller (5) and the mold conveyor belt (13) rotate and run.

[0027] Further, the casting discharge component includes a discharge groove 10 that communicates with the inside of the casting roller 5 and is radially arranged. An aluminum liquid containing cavity is arranged in the discharge groove 10. A plurality of discharge holes 11 are distributed at intervals on the bottom of the discharge groove 10. An inner cylinder 51 that rotates synchronously with the casting roller 5 is also arranged in the casting roller 5. Elastic discharge components 12 corresponding to the discharge holes 11 one by one are distributed on the inner cylinder 51. A cylindrical outer shell 52 is arranged outside the casting roller 5. The cylindrical outer shell 52 is fixedly erected through a support. Its inner wall is used to push the elastic discharge rod to close the discharge hole, and a notch is opened at the bottom end. Through the structure of the discharge groove, the aluminum liquid is powdered in the casting roller, and then discharged into the mold in an orderly manner through the discharge holes. During the process, the discharge holes ensure that only the discharge holes located at the bottom notch discharge through the interaction between the elastic discharge component and the cylindrical outer shell.

[0028] The elastic discharging assembly 12 includes guide sleeves 121 distributed on the outer circumferential surface of the inner cylinder 51 and corresponding to the discharging holes 11 one by one. A ejector rod 122 is installed in the guide sleeve 121 in a guiding manner. The ejector rod 122 is a stepped rod body. One end of the thin end of the ejector rod 122 is installed in the guide sleeve 121 in a clamping and guiding manner through a spring 124, and the other end is the thick end and is in sealing cooperation with the discharging hole 11. A universal ball 123 is installed at the end of the thick end of the ejector rod 122. The guide sleeve guides the ejector rod, and the end of the ejector rod is connected by a spring, having a certain elasticity, so that the ejector rod has a certain telescopic performance. This assembly method can play a good guiding role in the ejector rod and ensure the smoothness of the telescopic movement of the ejector rod. As the casting drum rotates, the ejector rod enters the cylindrical shell. The thick end of the end ejector rod contracts under the action of the cylindrical shell, thereby closing the discharging hole. In order to achieve a better closing effect, the thick end can be set to be slightly longer than the casting drum, and a trumpet-shaped inlet is provided at the cylindrical notch, so as to ensure the form of the gradual telescopic movement of the ejector rod and ensure the smoothness of the ejector rod during the process of pushing in and pushing out.

One end of the horizontal section of the casting pipeline 4 is connected to the aluminum ladle outlet, the other end passes through the aluminum liquid inlet and is connected to the inclined section, and the discharging end of the inclined section faces the position at the bottom end of the casting drum 5. Through the setting of the casting pipeline, the aluminum liquid can be introduced from the aluminum ladle into the casting drum. Through the structural design of the horizontal section and the inclined section, the aluminum liquid can be concentrated and introduced into the lowest discharging groove in the middle, while concentrating the feeding and discharging, ensuring the stability of the aluminum liquid during the casting process and effectively reducing the oxidation of aluminum, avoiding vortex and splashing.

[0030] Further, the scraping mechanism includes a scraping wheel 18 installed at the bottom of the flue gas collection box. Scrapers 19 for removing the oxide film on the surface of the aluminum ingot groove 14 are distributed at intervals in the circumferential direction of the scraping wheel 18. The rotating speeds of the scraping wheel 18 and the scrapers 19 are consistent with the speed of the mold conveyor belt 13. The scrapers are used to remove the oxide film, that is, to scrape off a large amount of oxidized slag floating on the surface of the melt;

[0032] After the molten aluminum in the aluminum ingot groove of the mold conveyor belt is formed by a blower, it is evenly cooled on the conveyor line, ensuring timely cooling and quenching during the small star process and guaranteeing the product quality. The grinding mechanism includes a grinding roller 21 rotatably installed at the bottom of the flue gas collection box. A grinding brush sleeve 22 is sleeved on the circumferential surface of the grinding roller 21. The grinding roller is driven by a motor to rotate, and the grinding roller drives the grinding brush sleeve to rotate. The grinding brush sleeve grinds the surface of the formed aluminum ingot to ensure the product quality. The aluminum ingot casting, surface grinding, and flue gas collection are all completed on the same production line, reducing the subsequent surface treatment process, improving the product quality, enabling it to fully meet the requirements of the steelmaking production for the aluminum ingot quality.
