Abstract
Description
Technical Field
[0001] This application relates to the field of experimental simulation technology for deep well casting in aluminum processing, and in particular to a simulation system and method for the explosion of molten aluminum upon contact with water in deep well casting of aluminum processing. Background Technology
[0002] Currently, in the deep-well casting process for aluminum processing, the casting well stores a certain amount of circulating cooling water, and is in an environment where high-temperature molten aluminum and cooling water coexist for a long time. When equipment malfunctions or improper operation occurs, the high-temperature molten aluminum may leak and fall into contact with the cooling water at the bottom of the well. When the high-temperature molten aluminum comes into contact with the cooling water, the temperature of the aluminum reaches 700-760℃, which will produce complex physicochemical reactions. At the same time, the cooling water will rapidly vaporize and expand, and the aluminum reaction will also produce hydrogen gas, triggering a devastating explosion and seriously affecting production safety.
[0003] Therefore, improvements are needed to the existing deep-well casting process for aluminum processing. However, these improvements require extensive simulation experiments to provide guidance and a basis for implementation. The simulation of the explosion of molten aluminum upon contact with water in deep-well casting for aluminum processing faces several challenges, including the difficulty in replicating the actual production environment and the inability to guarantee safety during the simulation process.
[0004] Therefore, there is a need for a simulation system and method for the explosion of molten aluminum in water during deep well casting of aluminum processing, which can reproduce the actual production environment and improve safety. Summary of the Invention

[0009] Furthermore, the mounting bracket is suspended directly above the plug, so that the lead wire runs vertically from the pulley to the plug.
[0010] Furthermore, it also includes a high-speed camera, pointed at the experimental container, to record the reaction process of molten aluminum exploding upon contact with water.
[0011] Furthermore, a thermocouple array is arranged on the iron cap to monitor temperature changes during the reaction.
[0012] Furthermore, a baffle is placed at the top opening of the experimental container, and a control lever is connected to the baffle; a support frame is also included, and the control lever is placed on the support frame.
[0013] Furthermore, the stopper includes a stopper body and a plugging end; a stepped surface is formed between the plugging end and the stopper body; the second open end is provided with an abutting platform, the stepped surface abuts against the abutting platform, and the plugging end extends outward from the funnel; it also includes a nut, the nut is threadedly connected to the plugging end and abuts against the outside of the funnel; the outer contour of the nut is provided with a groove, and a pull cable is wound in the groove, the pull cable causing the nut to rotate and disengage from the plugging end when pulled.
[0014] Furthermore, the nut is provided with an elastic element, one end of which is connected to the bottom of the nut and the other end abuts against the plug end. The elastic element has elastic potential energy to drive the plug away from the nut.

[0027] Example 1 Reference Figure 1 As shown, this embodiment provides a simulation system for the explosion of molten aluminum upon contact with water in deep well casting for aluminum processing, including a high-frequency melting furnace 1, an experimental platform 2, a transfer container 3, and an experimental container 4.
[0028] The high-frequency melting furnace 1 is used to prepare molten aluminum. In this embodiment, a high-frequency melting furnace 1 with a melting capacity of 10-30 kg of aluminum can be selected. (Refer to...) Figure 4 As shown, the experimental frame 2 includes a mounting surface 21 and a mounting bracket 22. A funnel 5 is mounted on the mounting surface 21. Specifically, the center of the mounting surface 21 can be hollowed out, and the funnel 5 is placed in the hollowed-out area and connected to the mounting surface 21 with bolts. The funnel 5 includes a first open end 51 and a second open end 52. The area of the first open end 51 is larger than the area of the second open end 52, so that the funnel 5 is arranged vertically. Molten aluminum is transferred into the funnel 5, and the molten aluminum can flow downward from the second open end 52 of the funnel 5.
[0029] Reference Figure 5 As shown, a plug 53 is provided inside the second opening end 52. By blocking the second opening end 52 with the plug 53, when transferring molten aluminum into the funnel, the molten aluminum is first retained in the funnel 5. After personnel evacuate, the plug 53 is pulled out to allow the molten aluminum to flow out. The mounting frame 22 is equipped with a pulley 23, and a lead wire 24 is wound around the pulley 23. One end of the lead wire 24 is connected to the plug 53, and the other end extends outside the experimental platform 2, so that pulling the lead wire 24 can pull out the plug 53. After personnel evacuate, the lead wire 24 can be pulled remotely to detach the plug 53 from the funnel 5 for remote start-up, improving safety. The plug 53 can be made of cast iron material, which is heat-resistant and avoids reaction with molten aluminum.
[0030] The transfer container 3 is used to hold molten aluminum and then transfer it to the funnel 5. Specifically, a connecting lug can be provided on the side of the transfer container 3. By inserting a lifting rod 31 into the connecting lug, the experimenter can lift the transfer container 3 to the position of the experimental stand 2 and pour the molten aluminum into the funnel 5. The transfer container 3 can be a crucible.
[0031] Specifically, the experimental container 4 is located below the funnel 5 and is used to hold water. The top of the experimental container 4 is open, and a simulation component is installed inside. The simulation component includes a vertical rod 41 and an iron cap 42. One end of the vertical rod 41 is connected to the bottom of the experimental container 4, and the other end is connected to the iron cap 42, making the iron cap 42 suspended. The experimental container 4 simulates a casting well, and the iron cap 42 simulates a spool tray, which can simulate the closed environment in the actual production process. During the experiment, the molten aluminum in the funnel 5 flows into the experimental container 4 and reacts with the water inside the experimental container 4.
[0032] This embodiment provides a simulation system for the explosion of molten aluminum upon contact with water in deep-well casting of aluminum processing. An iron cap 42 is suspended within an experimental container 4 via a support rod 41. The iron cap 42 simulates the ingot tray, and the experimental container 4 simulates the casting well. This system more accurately replicates the actual production environment within the casting well, making the experimental results closer to real-world conditions and providing more precise guidance for the modification of processes and equipment in deep-well casting of aluminum processing. During the experiment, the stopper 53 is pulled apart from the funnel 5 by the lead wire 24, allowing the molten aluminum to flow into the experimental container 4. This realistically simulates aluminum leakage and allows for remote initiation of the experiment, improving safety.
[0033] Specifically, refer to Figure 3As shown, the upright 41 includes a double-threaded sleeve 43 and two threaded rods 44. The two ends of the double-threaded sleeve 43 are respectively connected to the two threaded rods 44, so that the two threaded rods 44 move away from or closer to each other when the double-threaded sleeve 43 is rotated. One threaded rod 44 is connected to the bottom of the experimental container 4, and the other threaded rod 44 is connected to the iron cap 42. By rotating the double-threaded sleeve 43, the length of the upright 41 can be adjusted, thereby adjusting the height of the iron cap 42. This allows for the simulation of leakage under different heights of the ingot tray according to the actual production environment.
[0034] It should be noted that in the actual production process of deep-well casting in aluminum processing, the height of the dummy plate varies at different casting stages. For example, at the beginning of casting, the dummy plate is located above the casting well, and as casting continues, the dummy plate gradually descends. In this embodiment, an iron cap 42 is used to simulate the dummy plate, and it is necessary to consider the scenario of leakage occurring at different heights of the dummy plate. Therefore, in this embodiment, the height of the iron cap 42 can be adjusted according to different casting stages to conduct multiple tests, simulate aluminum molten metal leakage scenarios at different casting stages, and collect corresponding data.
[0035] Specifically, the experimental container 4 includes an outer cylinder 46 and an inner cylinder 45; the outer cylinder 46 is open at both ends, the inner cylinder 45 is open at the top, a threaded rod 44 is welded to the bottom of the inner cylinder 45, and the outer cylinder 46 is fitted over the inner cylinder 45. After adjusting the height of the upright 41, the outer cylinder 46 is fitted over the inner cylinder 45. The height adjustment is convenient, and the inner cylinder 45 can hold water, preventing water leakage.
[0036] It should be noted that in this embodiment, the experimental container 4 and the iron cap 42 are used to simulate the confined space during aluminum molten leakage. The experimental container 4 can be a long and thin square tube, that is, in this embodiment, the outer cylinder 46 can be a long and thin square tube. Different casting well structures have different depths, generally including 10 meters, 12 meters, and 16 meters. In this embodiment, the experimental container 4 of the appropriate size can be selected according to different casting well structures, specifically, the outer cylinder 46 of the appropriate size can be selected. This can further simulate aluminum molten leakage scenarios at different casting well depths, providing more comprehensive experimental data. In this embodiment, the size of the experimental container 4 can be selected to form a certain ratio with the actual casting well, such as 1:10 or 1:20, etc.
[0037] It should be noted that in the actual process of deep-well casting in aluminum processing, the dummy bar has different shapes, and the iron cap 42 can be designed with a shape corresponding to the dummy bar. (Refer to...) Figure 6 As shown, the shape of the iron cap 42 can be a flat plate structure; in Figure 7As shown, the iron cap 42 can be shaped like a frustum, with its surface forming a roof-like structure, and the slope of its surface can also be chosen in different ways; see reference. Figure 8 As shown, the iron cap 42 can also be hollow. In different simulation experiments, iron caps 42 of different shapes can be selected to simulate corresponding tumbler shapes, thus simulating the downward flow of molten aluminum in tumbler structures of different shapes, thereby obtaining more experimental data. The size of the tumbler is smaller than the size of the casting well; therefore, the size of the iron cap 42 is designed to be smaller than the size of the experimental container 4, creating a gap between the iron cap 42 and the inner wall of the experimental container 4. The specific size of the gap can be selected according to the actual process parameters of deep-well casting in aluminum processing.
[0038] Specifically, the mounting bracket 22 is suspended directly above the plug 53, so that the lead wire 24 is vertical from the pulley 23 to the plug 53. When the lead wire 24 is pulled, the plug 53 can be lifted vertically, making it easy to remove the plug 53.
[0039] Specifically, it also includes a high-speed camera, pointed towards the experimental container 4, to record the reaction process of molten aluminum exploding upon contact with water. Specifically, a thermocouple array is arranged on the iron cap 42 to monitor temperature changes during the reaction. The ability to record both the reaction process and temperature changes separately allows for a better understanding of the reaction process and data changes, leading to improved equipment and processes for deep-well casting in aluminum processing.
[0040] Specifically, it also includes a panoramic camera, an infrared monitoring camera, and a pressure sensor. The panoramic camera and infrared monitoring camera are used to capture the entire experimental process, recording the process to facilitate post-experiment review and correction. The pressure sensor is placed on the iron cap 42 and the experimental container 4 to monitor the shock wave generated during the explosion, recording experimental data more accurately.
[0041] Specifically, a baffle 6 is placed at the top opening of the experimental container 4, and a control lever 61 is connected to the baffle 6; a support frame is also included, on which the control lever 61 is placed. This forms a double protection, preventing leakage and contact with water in the experimental container 4 when the experimenter pours molten aluminum into the funnel 5, and ensuring that the experimenter has sufficient time to evacuate.
[0042] Specifically, refer to Figure 5As shown, the stopper 53 includes a stopper body 531 and a sealing end 532; a stepped surface is formed between the sealing end 532 and the stopper body 531; the second open end 52 is provided with an abutting platform, the stepped surface abuts against the abutting platform, and the sealing end 532 extends outward from the funnel 5; it also includes a nut 54, which is threadedly connected to the sealing end 532 and abuts against the outside of the funnel 5; the outer contour of the nut 54 is provided with a groove 541, and a pull cable 55 is wound in the groove 541. When the pull cable 55 is pulled, it causes the nut 54 to rotate and disengage from the sealing end 532. By connecting the sealing end 532 of the stopper 53 with the nut 54, the stability of the stopper 53 can be ensured, the sealing performance can be improved, and the leakage of aluminum liquid in the funnel 5 before the experiment is started can be avoided as much as possible to prevent safety accidents. When the experiment is started, since the cable 55 is wrapped around the nut 54, pulling the cable 55 from a distance will cause the nut 54 to rotate and separate from the plug 53. The separated nut can fall on the baffle 6 and take the plug 53 with it when the baffle 6 is pulled away.
[0043] Specifically, the nut 54 contains an elastic element 542. One end of the elastic element 542 is connected to the bottom of the nut 54, and the other end abuts against the plug end 532. The elastic element 542 has elastic potential energy to drive the plug 53 away from the nut 54. During the process of pulling the cable 55 to disengage the nut 54, a certain gap is formed between the nut 54 and the bottom of the funnel 5. The elastic potential energy of the elastic element 542 applies an upward force to the plug 53, which can loosen the plug 53 and prevent the plug 53 from getting stuck in the second port of the funnel 5. This allows the plug 53 to be pulled out smoothly when the lead wire 24 is pulled, ensuring the reliability of the experiment.
[0044] Example 2 Reference Figure 9 As shown, this embodiment provides an experimental method using the simulation system in Embodiment 1, including the following steps: Preparation phase: Aluminum ingots are smelted using a high-frequency melting furnace 1 to form high-temperature molten aluminum liquid; Aluminum liquid transfer stage: Pour the molten aluminum in the high-frequency melting furnace 1 into the transfer container 3; The operator lifts the transfer container 3, moves it to the position of the experimental platform 2, and pours the molten aluminum into the funnel 5; Experimental phase: All personnel were evacuated to a location at least 410 meters away from the experimental container. Pulling the lead wire 24 causes the stopper 53 to detach from the second opening end 52 of the funnel 5, and the molten aluminum flows from the funnel 5 into the experimental container 4 to react.
[0045] The experimental method provided in this embodiment can more realistically simulate the actual production environment. The starting method, which separates the plug 53 from the funnel 5 by pulling the lead wire 24, allows for the early evacuation of experimental personnel and remote starting, avoiding injury to experimental personnel from explosion and improving safety.
[0046] Specifically, during the experimental preparation stage, 10-30 kg of molten aluminum can be smelted according to the experimental requirements. Simultaneously, the equipment is inspected to ensure that funnel 5 is securely installed, that stopper 53 completely seals funnel 5 without leakage, and that lead wire 24 is undamaged. Water is injected into experimental container 4; the water depth can be determined according to experimental needs. In this embodiment, the water depth is 300 mm. Baffle 6 is placed above experimental container 4, ensuring that baffle 6 completely covers the opening of experimental container 4. A high-speed camera is positioned, and K-type thermocouples are evenly arranged on the iron cap 42 at 100 mm intervals.
[0047] During the aluminum liquid transfer stage, after the aluminum liquid is heated to 750±10℃, a forklift is used to lift the high-frequency melting furnace 1 and transfer the aluminum liquid into the transfer container 3.
[0048] During the experiment, the cable 55 is first pulled to separate the nut 54 from the stopper 53, causing the stopper 53 to fall above the baffle 6. Then, one operator holds the lever 61 to pull away the baffle 6, while another operator simultaneously pulls the lead wire 24 to remove the stopper 53, allowing the molten aluminum in the funnel 5 to flow into the reaction vessel and come into contact with water, thus initiating the reaction. Before pulling the lead wire 24 to remove the stopper 53, a high-speed camera is activated for recording; the high-speed camera has a sampling rate of 100Hz.
[0049] Experimental data were obtained by capturing the interface dynamics during the aluminum-water reaction using a high-speed camera and measuring the temperature using a thermocouple.
[0050] After the experiment is completed, wait for the temperature of experimental container 4 to drop below 60°C, which usually takes 40 minutes, before cleaning the site.
[0051] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0052] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
