Description

Technical Field

[0001] The present invention belongs to the technical field of casting and rolling process, and specifically relates to a liquid level control device suitable for casting and rolling process. Background Art

[0002] Aluminum alloy is a non-ferrous metal alloy material with low density, good strength and plasticity. It is widely used in mechanical manufacturing, electronics industry, aerospace and other fields. With the rapid development of the transportation industry and aerospace field, the demand for lightweight, strong and plastic materials has increased, giving aluminum alloy materials a broader prospect. The main processing methods of aluminum alloy materials include gravity casting, die casting, continuous casting, twin-roll casting, etc. Twin-roll casting is a short-process near-net-shape forming process with the characteristics of short production cycle and high efficiency.

[0003] During the casting and rolling process of aluminum alloy sheet production, it's inevitable that the automatic flow control system will fail, and liquid level fluctuations, such as those caused by furnace reversal and replacement, can cause the aluminum alloy sheets to bulge and slip. Traditionally, the solution to bulge has been manual adjustment of the flow control level, assisted by a secondary flow control device. However, when the liquid level is too high, the effectiveness of traditional devices is greatly reduced, and bulge will still occur. There is no specific solution to the slipping problem in China. Practical results have shown that liquid level fluctuations significantly impact the yield rate and quality of the end product.

[0004] In summary, it is necessary to develop a device that can solve both edge expansion and edge slippage problems, which is low-cost and reusable to ensure stable production. Utility Model Content

[0005] In order to solve the above problems, this paper proposes a liquid level control device suitable for the casting and rolling process. The liquid level control device is conductively connected to the casting and rolling process. The liquid level control device includes a main chute and an auxiliary chute. The bottom of the main chute is conductively connected to the casting and rolling process. The outer side of the main chute is conductively connected and provided with an auxiliary chute. The auxiliary chute is in the shape of an arc-shaped hollow conductive trough. The upper and lower ends of the auxiliary chute are respectively conductively connected to the upper and lower ends of the outer side of the main chute. An overflow port is provided in the transverse conductive manner on the upper outer side of the auxiliary chute. An aluminum silicate fiber blanket is embedded in the connection between the upper end of the auxiliary chute and the main chute. A buoyancy sealing block is provided on the outside of the connection between the lower end of the auxiliary chute and the main chute. One side of the buoyancy sealing block is fitted with a sealing It is connected to the lower opening of the auxiliary chute, and the bottom of the buoyancy sealing block is axially connected to the inner wall of the main chute by a single-sided hinge. By setting an additional conductive auxiliary chute on the outside of the original main chute, the upper and lower ends of the main chute are connected, and a buoyancy sealing block is set at the bottom conductive opening of the main chute and the auxiliary chute, so that the inclination angle position of the buoyancy sealing block can be controlled by the liquid level height in the main chute to control the conduction between the bottom of the main chute and the auxiliary chute, and then the retained liquid in the auxiliary chute can realize automatic stable control of the liquid level, effectively reducing liquid level fluctuations, reducing the frequency of rising and sliding edges, improving the yield rate of aluminum alloy plates in the casting and rolling process, and ensuring the quality of the end product.

[0006] The main chute is in the shape of a vertical single-pass rectangular cylinder. Liquid level adjustment openings are provided at both ends of one side surface of the main chute in a transversely symmetrical manner. The inner cavity of the main chute is connected to the inner cavity of the auxiliary chute through the liquid level adjustment opening. The bottom conductive opening of the main chute is connected to the casting and rolling process. By arranging liquid level adjustment openings at the upper and lower ends of the main chute to make it connected to the auxiliary chute, it can be achieved that when the liquid level is too high, it can flow from the upper end into the auxiliary chute for storage.

[0007] The auxiliary chute is in the shape of a rectangular curved pipe trough with both ends connected. The cross-section of the auxiliary chute is rectangular. The two sides of the auxiliary chute are arranged parallel to the outside of the main chute. The distance between the maximum arc edge of the outer side of the auxiliary chute and the outer surface of the main chute is less than twice the width of the main chute. The curved auxiliary chute can fully ensure that the internal liquid can be smoothly introduced into the main chute from below, and by limiting the curvature of the auxiliary chute, the liquid storage and water pressure strength of the auxiliary chute are guaranteed to prevent the buoyancy sealing block from being pushed open due to excessive hydraulic pressure.

[0008] The overflow port is in the shape of a rectangular opening. The overflow port is horizontally arranged on the upper outer side of the auxiliary chute. One end of the overflow port is conductively connected to the interior of the auxiliary chute. The distance between the overflow port and the top surface of the auxiliary chute is one-fourth of the height of the auxiliary chute. The overflow opening is used to prevent the main chute and the auxiliary chute from being filled with liquid, which would cause excessive pressure and damage to internal equipment.

[0009] The aluminum silicate fiber blanket is a plug-in type fiber blanket, which is arranged at intervals between the upper end of the main chute and the connection between the auxiliary chute. The aluminum silicate fiber blanket is used to block the connection between the main chute and the auxiliary chute.

[0010] The buoyancy sealing block is in the shape of a rectangular block. The end face size of the buoyancy sealing block fitted with the lower end opening of the auxiliary chute is larger than the lower end opening size of the auxiliary chute. The length of the buoyancy sealing block is less than half of the inner width of the main chute. The top surface of the buoyancy sealing block is provided with a snap-in groove. The lower side of the side surface of the buoyancy sealing block connected to the lower end opening of the auxiliary chute is provided with a flip hinge. The snap-in groove is connected to the counterweight block. A slot for adjusting the weight of the device is installed on the top of the buoyancy sealing block. The weight on the top is different according to the original liquid level of different casting and rolling machines.

[0011] The flip hinge is an axial hinge welded with aluminum plates. The outer surface of the flip hinge is provided with ceramic fiber material. The device is made of high temperature resistant and corrosion resistant materials. If the surface is damaged, the interior is still made of aluminum, and there is no damage to the melt quality.

[0012] Beneficial effects:

[0013] By setting up an additional conductive auxiliary chute outside the original main chute, the upper and lower ends of the main chute are connected, and a buoyancy sealing block is set at the bottom conductive opening of the main chute and the auxiliary chute, so that the inclination angle position of the buoyancy sealing block can be controlled by the liquid level height in the main chute to control the conduction between the bottom of the main chute and the auxiliary chute, and then the retained liquid inside the auxiliary chute can realize automatic stable control of the liquid level, effectively reducing liquid level fluctuations, reducing the frequency of rising and sliding edges, improving the yield rate of aluminum alloy plates in the casting and rolling process, and ensuring the quality of the end product.

[0014] By setting liquid level adjustment openings at the upper and lower ends of the main chute to make it communicate with the auxiliary chute, when the liquid level is too high, it can flow from the upper end into the auxiliary chute for storage.

[0015] The curved auxiliary chute can fully ensure that the internal liquid can be smoothly introduced into the main chute from below, and by limiting the curvature of the auxiliary chute, the liquid storage and water pressure strength of the auxiliary chute can be guaranteed to prevent the buoyancy sealing block from being pushed open due to excessive hydraulic pressure.

[0016] Overflow openings are used to prevent the main chute and auxiliary chute from being filled with liquid, which would cause excessive pressure and damage the internal equipment.

[0017] The device is made of high-temperature resistant and corrosion-resistant materials. If the surface is damaged, the interior is still made of aluminum, and there is no damage to the melt quality. The top of the buoyancy sealing block is equipped with a slot that can adjust the weight of this device. The weight on the top varies depending on the original liquid level of different casting and rolling machines.

[0018] When the liquid level in the main chute is stable, the weight of the buoyancy sealing block is equal to the buoyancy brought by the liquid surface of the main chute, and the auxiliary chute does not work; when the liquid level in the main chute is low, the weight of the buoyancy sealing block is greater than the buoyancy, the buoyancy sealing block tilts, and the molten aluminum in the auxiliary chute can flow into the main chute; when the liquid level in the main chute is high, the molten aluminum in the main chute flows into the auxiliary chute for insulation, and when the capacity of the auxiliary chute is large, it can flow out through the overflow port (the connection between the main chute and the auxiliary chute is sealed with an aluminum silicate fiber blanket).
