Description

Technical Field

[0001] The utility model relates to the technical field of aluminum ingot processing, in particular to a cooling structure before aluminum ingot rolling. Background Art

[0002] Aluminum ingots are aluminum metal block products with high purity obtained through melting and smelting processes, usually called aluminum ingots. In industry, aluminum ingots are mainly divided into two categories after entering the application: cast aluminum alloy and deformed aluminum alloy. Cast aluminum and aluminum alloys are aluminum castings produced by casting methods, while deformed aluminum and aluminum alloys are aluminum processed products produced by pressure processing methods, such as plates, strips, foils, tubes, bars, profiles, wires and forgings.

[0003] Aluminum ingots are cooled before rolling to adjust the temperature of the aluminum ingots so that the subsequent rolling process can be smoother and more efficient. Existing cooling methods often use air cooling and water cooling. During the cooling process, the cooling speed and temperature uniformity cannot be controlled, which can easily cause excessive stress or temperature difference inside the aluminum ingot, leading to deformation or cracking problems. Utility Model Content

[0004] The utility model discloses a cooling structure before rolling of an aluminum ingot, aiming to solve the technical problem that during the cooling process, the cooling speed and temperature uniformity cannot be controlled, which easily causes excessive stress or temperature difference inside the aluminum ingot, resulting in deformation or cracking and other problems.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A pre-rolling cooling structure for an aluminum ingot comprises an aluminum ingot body and a cooling box, and further comprises:

[0007] A cooling mechanism, the cooling mechanism comprising three water distribution pipes, the circumferential outer wall of the water distribution pipe is provided with equidistantly distributed down pipes, the bottom of the down pipe is provided with a nozzle, the bottom and the circumferential outer wall of the nozzle are provided with evenly distributed spray holes, and the circumferential outer wall of the spray hole is provided with evenly distributed fan blades;

[0008] Conduction mechanism for transferring heat.

[0009] In this solution, the evenly distributed nozzles allow the blown wind and water mist to be evenly spread on the aluminum ingot body, making the cooling more uniform, avoiding excessive stress or temperature difference inside the aluminum ingot body, causing cracking or deformation, and ensuring that the cooling effect meets the needs of subsequent rolling.

[0010] In a preferred embodiment, a water pump is provided on one side outer wall of the water tank, a water supply pipe is provided on the top of the water pump, a water diversion port is provided on one side outer wall of the cooling box, the top end of the water supply pipe is fixedly connected to the water diversion port, a water guide pipe is provided on the top of the water diversion port, and one end of the water guide pipe is fixedly connected to the water diversion pipe.

[0011] By adopting the above scheme, the temperature of the water in the water tank increases after heat exchange, and the water mist sprayed from the nozzle is more easily vaporized in the cooling box, which can quickly absorb the heat of the aluminum ingot body and reduce the temperature of the aluminum ingot body. The surface of the aluminum ingot body will not come into contact with the cold water, avoiding uneven cooling on the surface of the return air duct, causing temperature differences and damaging the internal structure of the aluminum ingot body.

[0012] As can be seen from the above, a cooling structure for aluminum ingot before rolling includes an aluminum ingot body and a cooling box, and also includes:

[0013] A cooling mechanism, the cooling mechanism comprising three water distribution pipes, the circumferential outer wall of the water distribution pipe is provided with equidistantly distributed down pipes, the bottom of the down pipe is provided with a nozzle, the bottom and the circumferential outer wall of the nozzle are provided with evenly distributed spray holes, and the circumferential outer wall of the spray hole is provided with evenly distributed fan blades;

[0014] The conductive mechanism is used to transfer heat. The aluminum ingot pre-rolling cooling structure provided by the utility model has the technical effect of making the aluminum ingot body cool more evenly, avoiding excessive stress or temperature difference inside the aluminum ingot body, causing cracking or deformation, and ensuring that the cooling effect meets the requirements of subsequent rolling.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0022] The utility model discloses an aluminum ingot pre-rolling cooling structure which is mainly used in scenarios where the cooling speed and temperature uniformity cannot be controlled during the cooling process, which may easily cause excessive stress or temperature difference inside the aluminum ingot, leading to problems such as deformation or cracking.

[0023] Reference Figure 1 , Figure 2 and Figure 3 , an aluminum ingot pre-rolling cooling structure, comprising an aluminum ingot body 2 and a cooling box 6, and also comprising:

[0024] The cooling mechanism includes three water distribution pipes 11. The circumferential outer wall of the water distribution pipe 11 is provided with equidistantly distributed down pipes 10. The bottom of the down pipe 10 is provided with a nozzle 14. The bottom and circumferential outer wall of the nozzle 14 are provided with evenly distributed spray holes 13. The circumferential outer wall of the spray hole 13 is provided with evenly distributed fan blades 12.

[0025] Conduction mechanism for transferring heat.

[0026] Specifically, the nozzle 14 is rotatably connected to the downpipe 10, and a motor is provided in the nozzle 14. When in use, water mist is sprayed from the spray hole 13 on the nozzle 14. At the same time, the nozzle 14 and the fan blades 12 rotate to blow air downward, and the fan is used to accelerate the air flow and the thermal conductivity of water to quickly cool down. During the cooling process, the evenly distributed nozzles 14 make the blown wind and water mist evenly spread on the aluminum ingot body 2, making the cooling more uniform, avoiding excessive stress or temperature difference inside the aluminum ingot body 2, causing cracking or deformation and other problems, and ensuring that the cooling effect meets the needs of subsequent rolling.

[0027] Reference Figure 1 , Figure 3 and Figure 4In a preferred embodiment, the conduction mechanism includes a return air duct 1 and a water tank 8 located at the bottom of the return air duct 1, the two ends of the return air duct 1 are fixedly connected to the upper and lower sides of the cooling box 6 respectively, the bottom of the return air duct 1 is provided with evenly distributed heat conducting plates 15, the bottom of the heat conducting plates 15 is located inside the water tank 8, and the bottom of the return air duct 1 is provided with evenly distributed return holes 16, which are connected to the inside of the water tank 8.

[0028] Specifically, the wind blown out by the fan blades 12 and the water mist sprayed out by the nozzles 13 gather downward, and the wind passes through the heat conductive sheet 15 in the return air duct 1. After the heat is conducted away, the wind flows upward in the return air duct 1 and is blown into the cooling box 6 again to form a circulating air supply. The heat conductive sheet 15 conducts heat to reduce the temperature in the return air duct 1. At the same time, the water in the water tank 8 is heated. The water mist gathers at the bottom of the return air duct 1 and flows into the water tank 8.

[0029] Reference Figure 1 , Figure 2 and Figure 3 In a preferred embodiment, a water pump 9 is provided on one side outer wall of the water tank 8, a water pipe 7 is provided on the top of the water pump 9, a water diversion port 5 is provided on one side outer wall of the cooling box 6, the top of the water pipe 7 is fixedly connected to the water diversion port 5, a water guide pipe 4 is provided on the top of the water diversion port 5, and one end of the water guide pipe 4 is fixedly connected to the water diversion pipe 11.

[0030] Specifically, the water in the water tank 8 is pressurized and transported by the water pump 9, passes through the water delivery pipe 7 and the water distribution pipe 11, and is sprayed out from the nozzle 14. Since the temperature of the water in the water tank 8 increases after heat exchange, the water mist sprayed from the nozzle 14 is more easily vaporized in the cooling box 6, which can quickly absorb the heat of the aluminum ingot body 2 and reduce the temperature of the aluminum ingot body 2. The surface of the aluminum ingot body 2 will not come into contact with the cold water, thereby avoiding uneven cooling of the surface of the return air duct 1, causing temperature differences and damaging the internal structure of the aluminum ingot body 2.

[0031] Reference Figure 1 In a preferred embodiment, a water injection pipe is provided on one side outer wall of the water tank 8, a conveyor belt 3 is provided in the cooling box 6, the aluminum ingot body 2 is placed above the conveyor belt 3, and baffles are provided on the left and right sides of the cooling box 6 to reduce the overflow of air and maintain the air circulation inside the cooling box 6.

[0032] Working principle: When in use, the water in the water tank 8 is pressurized and transported by the water pump 9, passes through the water delivery pipe 7 and the water distribution pipe 11, and sprays water mist from the spray hole 13 on the nozzle 14. At the same time, the nozzle 14 and the fan blade 12 rotate to blow air downward. The nozzle 14 makes the blown wind and water mist evenly spread on the aluminum ingot body 2. The wind and water mist gather downward. The wind passes through the heat conducting plate 15 in the return air duct 1. After the heat is conducted away, it flows back upward in the return air duct 1 and is blown into the cooling box 6 again. The air is circulated, and the heat conducting plate 15 conducts heat to reduce the temperature in the return air duct 1. At the same time, the water in the water tank 8 is heated, and the water mist gathers at the bottom of the return air duct 1 and flows into the water tank 8.

[0033] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited to this. The replacement can be a replacement of part of the structure, device, method step, or a complete technical solution. Equivalent replacement or change based on the technical solution of the utility model and its utility model concept should be included in the protection scope of the utility model.
