Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, specifically to a cooling device for rolling mill production. Background Technology

[0002] Rolls are core components in metal rolling processes, typically made of high-strength alloy steel or cast iron, and have cylindrical or irregular profiles. Their surfaces require precision grinding and heat treatment to withstand repeated rolling forces under high temperature and pressure. During production, rolls need to be cooled using cooling equipment. Traditional cooling equipment often fails to provide uniform airflow to the roll's outer surface, resulting in temperature differences that can lead to inconsistent surface flatness and negatively impact the quality of the finished roll. Utility Model Content

[0003] The purpose of this utility model is to provide a roll production air-cooling device to solve the problem mentioned in the background art that the traditional cooling equipment does not provide uniform air blowing treatment on the outer surface of the roll, resulting in temperature differences on the outer surface of the roll, which may lead to inconsistent flatness of the outer surface of the roll and affect the quality of the finished roll.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a cooling device for roll production, comprising a cooling tank, with support seats on both sides of the lower end of the cooling tank, and a first air curtain machine and a second air curtain machine respectively installed on the upper part of one side of the outer surface of the cooling tank. A liquid-gas heat exchanger is installed on the outer side of the cooling tank and below the first and second air curtain machines. A diffusion groove is connected between the lower ends of the first and second air curtain machines and the liquid-gas heat exchangers. A cooling pipe is installed through the interior of the two liquid-gas heat exchangers. A circulating fan is connected below the two liquid-gas heat exchangers. A circulating air duct is connected between the lower end of the circulating fan and the lower end of the side wall of the cooling tank.

[0005] Preferably, the cooling pipe is S-shaped and installed inside the two liquid-gas heat exchangers. The outer surface of the cooling pipe and inside the two liquid-gas heat exchangers are provided with fins, and both ends of the cooling pipe are provided with connecting flanges.

[0006] Preferably, the outer surface of the cooling tank is provided with a reinforcing frame, and the two ends of the cooling tank are provided with end plates, which are fixedly connected to the two ends of the reinforcing frame.

[0007] Preferably, the lower end of the support base is provided with a support frame, and the lower end of the support frame extends through the cooling groove and out of the cooling groove.

[0008] Preferably, the cooling pipe is connected to an external cold source via the connecting flange.

[0009] Compared with the prior art, the beneficial effects of this utility model are: it replaces the traditional roll cooling equipment, avoids direct blowing of cooling air onto the roll, makes the air blowing treatment on the outer surface of the roll more uniform, reduces the temperature difference on the outer surface of the roll, thereby ensuring that the flatness of the outer surface of the roll meets the production requirements and ensuring the quality of the finished roll.

Detailed Implementation

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] Please see Figure 1-5 This utility model provides a cooling device for roll production, including a cooling tank 1. Support seats 2 are provided on both sides of the lower end of the cooling tank 1. A first air curtain machine 3 and a second air curtain machine 4 are respectively provided on the upper part of one side of the outer surface of the cooling tank 1. A liquid-gas heat exchanger 5 is provided on the outer side of the cooling tank 1 and below the first air curtain machine 3 and the second air curtain machine 4. A diffusion groove 6 is respectively connected between the lower end of the first air curtain machine 3 and the second air curtain machine 4 and the liquid-gas heat exchanger 5. A cooling pipe 7 passes through the interior of the two liquid-gas heat exchangers 5. A circulating fan 8 is connected below the two liquid-gas heat exchangers 5. A circulating air duct 9 is connected between the lower end of the circulating fan 8 and the lower end of the side wall of the cooling tank 1.

[0014] In use, the roll 15 requiring cooling is placed on the support seat 2 inside the cooling tank 1. The support seat 2 supports the roll 15. The circulating fan 8 is started, drawing air from inside the cooling tank 1 through the circulating air duct 9. The air is drawn into the liquid-gas heat exchanger 5. The liquid-gas heat exchanger 5 is equipped with cooling pipes 7, which are connected to an external cold source. This allows the circulating air to exchange heat with the cooling pipes 7 after entering the liquid-gas heat exchanger 5, thus lowering the air temperature. Low-temperature air diffuses through the diffusion groove 6 into the interior of the first air curtain machine 3 and the second air curtain machine 4. The first air curtain machine 3 and the second air curtain machine 4 are set on one side of the cooling tank 1. The low-temperature air is blown out by the first air curtain machine 3 and the second air curtain machine 4, forming an air curtain on the upper surface of the cooling tank 1, which isolates the internal temperature of the cooling tank 1 from the external temperature, creating a low-temperature environment inside the cooling tank 1, thereby cooling the roll 15. The air inside the cooling tank 1 is then circulated by the circulating fan 8 to form circulating air.

[0015] The cooling pipe 7 is arranged in an S-shape inside the two liquid-gas heat exchangers 5. The outer surface of the cooling pipe 7 and inside the two liquid-gas heat exchangers 5 are provided with fins 10. Both ends of the cooling pipe 7 are provided with connecting flanges 11. The cooling pipe 7 is connected to an external cold source through the connecting flanges 11. The external cold source exchanges heat with the air through the fins 10 provided on the cooling pipe 7. The S-shaped arrangement of the cooling pipe 7 increases the contact area with the air.

[0016] The outer surface of the cooling tank 1 is provided with a reinforcing frame 12 to improve the overall strength of the cooling tank 1. The two ends of the cooling tank 1 are provided with end plates 13, which are fixedly connected to the two ends of the reinforcing frame 12 to seal the two ends of the cooling tank 1.

[0017] The lower end of the support base 2 is provided with a support frame 14. The lower end of the support frame 14 extends through the cooling groove 1 and out of the cooling groove 1, so as to support the lower end of the support base 2.

[0018] The cooling pipe 7 is connected to an external cold source via the connecting flange 11, providing a cold source for air heat exchange.

[0019] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
