Description

Technical Field

[0001] This utility model relates to the field of aluminum ingot processing, and in particular to a casting device for aluminum ingot processing. Background Technology

[0002] Aluminum ingots are produced by electrolysis using alumina-crystal. After entering industrial applications, aluminum ingots fall into two main categories: cast aluminum alloys and wrought aluminum alloys. Cast aluminum and aluminum alloys are aluminum castings produced by casting methods; wrought aluminum and aluminum alloys are aluminum processed products produced by pressure processing methods: plates, strips, foils, tubes, bars, profiles, wires, and forgings. During the production and processing of aluminum ingots, a casting device is required to cast the aluminum ingots into shape to facilitate the next step of processing.

[0003] Traditional aluminum ingot casting equipment often employs tilting casting or mechanical pump flow control, which suffers from problems such as large fluctuations in aluminum flow rate, easy clogging of the casting nozzle, and uneven spraying of the release agent. This results in numerous pores on the surface of the finished aluminum ingots, significant weight errors, and frequent shutdowns for cleaning and maintenance. Furthermore, in existing equipment, the release agent spraying system is separated from the casting structure, which can easily cause spraying delays or uneven coverage, affecting demolding efficiency and the surface quality of the aluminum ingots.

[0020] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0021] In the attached diagram, all identical reference numerals refer to the same components.

[0022] like Figure 1-2 As shown, this utility model provides a casting device for aluminum ingot processing. The main body 1 of the device is composed of a high-temperature resistant metal frame and has a vertically layered layout.

[0023] The feed inlet 2 is located at the top of the device and has a funnel-shaped structure, which is used to receive molten aluminum and guide it to the connecting structure below.

[0024] The connecting pipe 3 is vertically connected to the feed inlet 2 and the pouring nozzle 501, and is made of high-temperature resistant material. The electromagnetic pump 4 is integrated in the middle of the connecting pipe 3 and is used to drive and precisely regulate the flow rate of the molten aluminum.

[0025] The pouring nozzle 501 is located at the bottom of the connecting pipe 3, and an ultrasonic transducer 502 is embedded inside for periodic vibration to clean the inner wall. The pouring mold 505 is located directly below the pouring nozzle 501 and aligned with the outlet of the pouring nozzle 501, and is used to receive and shape the molten aluminum. The atomizing nozzle 503 is installed on the top edge of the mold, and the spray direction is aimed at the inner cavity of the mold. The release agent storage tank 504 is embedded in the outer shell of the fixing block 5, and is connected to the atomizing nozzle 503 through a pipe. A replenishment port is provided at the top for adding release agent.

[0026] The method of using this utility model is as follows:

[0027] 1. Before starting the device, preheat the casting mold 505 with external heating equipment or waste heat recovery system, and inject the release agent through the replenishment port at the top of the release agent storage tank 504 to ensure that the liquid level in the storage tank is sufficient.

[0028] 2. Molten aluminum liquid is transported from the smelting furnace to the feed inlet 2 through the pipeline and flows into the connecting pipe 3 by gravity. 1 to 2 seconds before the aluminum liquid is injected, the atomizing nozzle 503 is activated. The release agent is transported from the storage tank to the atomizing nozzle 503 through the pipeline and evenly covers the inner surface of the mold in the form of atomization to form an isolation layer and prevent aluminum ingots from sticking together.

[0029] 3. The control component determines whether the aluminum liquid has reached the set amount by the start time and flow rate of the electromagnetic pump 4. The control component turns off the electromagnetic pump 4, the aluminum liquid stops flowing, and the residual aluminum liquid in the pouring nozzle 501 drips into the mold by gravity. The control component starts the ultrasonic transducer 502, which generates a high frequency vibration frequency of 20~40kHz to break up the aluminum slag or oxides adhering to the inner wall of the pouring nozzle 501. The shaken residue is discharged with the next flow of aluminum liquid, keeping the inner wall of the pouring nozzle 501 smooth and unobstructed.

[0030] 4. The molten aluminum is allowed to stand and cool in the mold until the surface solidifies. External air cooling or other methods can be used to help the molten aluminum cool quickly and shorten the production cycle.

[0031] This invention relates to a casting device for aluminum ingot processing. The device precisely controls the flow rate of molten aluminum using an electromagnetic pump 4, and combines this with the periodic self-cleaning function of the built-in ultrasonic transducer 502 in the casting nozzle 501 to effectively prevent nozzle blockage and residual aluminum oxidation. A release agent spraying component is integrated into a fixed block 5, and the atomizing nozzle 503 precisely corresponds to the mold position, achieving uniform coverage of the release agent and significantly reducing the aluminum ingot adhesion rate. A control component coordinates the timing of the electromagnetic pump 4, ultrasonic transducer 502, and release agent spraying, improving production continuity and reducing manual intervention. The overall device combines the advantages of high precision, low maintenance, and high yield.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
