[0020] 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.

[0021] The purpose of this invention is to provide a bar roll cooling device to solve the problems existing in the prior art. It has a simple structure, is easy to use, and effectively improves the cooling effect.

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] This utility model provides a bar mill roll cooling device, such as... Figures 1-3 As shown, the device includes: a circular arc main water pipe 1, multiple nozzles 2, and a water pipe seat 4. The circular arc main water pipe 1 has an inlet 3 and multiple outlets. The inlet 3 is located on the outer side of one end of the circular arc main water pipe 1, and each outlet is located on the inner side of the circular arc main water pipe 1. Each nozzle 2 is detachably fixedly connected to one outlet. The water pipe seat 4 is detachably fixedly connected to one end of the circular arc main water pipe 1 so that the circular arc main water pipe 1 surrounds the roller. The water pipe seat 4 is provided with a first through hole for communicating with the inlet 3. Cooling water can flow smoothly into the circular arc main water pipe 1 from the inlet 3 and be precisely guided towards the roller for cooling through the inner outlets. The detachable fixed connection between the nozzles 2 and the outlets facilitates convenient and quick replacement when the nozzles 2 are blocked or damaged, reducing maintenance costs and improving the efficiency and service life of the device. The detachable connection between the water pipe seat 4 and the arc-shaped main water pipe 1 allows for flexible layout and installation of the device according to different roll diameters and specifications, making it highly adaptable. At the same time, the first through hole is connected to the water inlet 3 to ensure that cooling water can be supplied to the arc-shaped main water pipe 1 for cooling.

[0024] In a preferred embodiment, the nozzle 2 has a flat rectangular opening structure. The flat rectangular opening structure increases the output of cooling water and allows the cooling water to be distributed more evenly when sprayed onto the roll surface. This enables more comprehensive coverage of the roll surface, eliminates cooling blind spots, improves the uniformity of cooling effect, effectively avoids problems such as thermal cracks caused by insufficient local cooling of the roll, and further improves the cooling quality and service life of the roll.

[0025] In a preferred embodiment, each nozzle 2 is uniformly arranged along the inner side of the arc-shaped main water pipe 1. The uniform distribution of nozzles 2 along the inner side of the arc-shaped main water pipe 1 can ensure that the amount of cooling water and the cooling intensity received by each part of the roll surface are relatively consistent, further enhancing the uniformity of the cooling effect, so that the roll is uniformly cooled in the entire circumferential direction, reducing problems such as roll deformation and wear caused by uneven cooling, which is conducive to ensuring the quality stability of the product and extending the effective working cycle of the roll.

[0026] In a preferred embodiment, the angle between the orientation directions of adjacent nozzles 2 is 19°. This specific 19° angle setting allows cooling water to be periodically sprayed onto the roll surface at different angles. By utilizing the relative speed between the roll and the cooling water, the water pressure is indirectly enhanced, which is more conducive to the cooling water penetrating the local vapor film on the roll surface, further improving the cooling efficiency and effect, optimizing the cooling state of the roll surface, and improving the cooling quality of the roll.

[0027] In a preferred embodiment, the cross-sectional area of ​​the inlet 3 is greater than the sum of the cross-sectional areas of each nozzle 2. This ensures that the pressure change caused by the change in cross-sectional area during the flow of cooling water from the inlet 3 to each nozzle 2 after entering the arc-shaped main water pipe 1 guarantees a sufficient pressure difference, increases the cooling area, and increases the pressure of the cooling water reaching the surface of the roll. This allows the cooling water to be sprayed onto the roll more forcefully, enhancing the cooling effect and ensuring that the cooling water can effectively cool the roll.

[0028] In a preferred embodiment, a connecting base plate 5 is further included. The connecting base plate 5 is integrally connected to the arc-shaped main water pipe 1, and the water inlet 3 passes through the connecting base plate 5. The connecting base plate 5 is used for detachable fixed connection with the water pipe seat 4. The integral connection between the connecting base plate 5 and the arc-shaped main water pipe 1 enhances the overall integrity and stability of the cooling device structure, and helps to improve the reliability of the device during operation. At the same time, the detachable connection between the connecting base plate 5 and the water pipe seat 4 facilitates the installation, disassembly, maintenance, and transportation of the device, enabling the device to be quickly and efficiently configured and adjusted to adapt to different steel rolling production environments.

[0029] In a preferred embodiment, the device further includes multiple fixing bolts. The connecting base plate 5 has multiple second through holes, and the outer side of the first through hole of the water pipe seat 4 has multiple third through holes. The fixing bolts pass through the second and third through holes to secure the connecting base plate 5 and the water pipe seat 4. This fixing method, using fixing bolts passing through the corresponding through holes, is simple, convenient, quick, and provides a reliable connection. When maintenance, repair, or component replacement is required, the device can be easily disassembled, facilitating corresponding operations by personnel. Simultaneously, it ensures a stable connection between the connecting base plate 5 and the water pipe seat 4 during device operation, guaranteeing the normal operation of the entire bar roll cooling device.

[0030] In a preferred embodiment, the water pipe seat 4 is provided with multiple mounting holes for bolt connection to the finishing mill. These mounting holes on the water pipe seat 4 provide a convenient way to connect the entire bar roll cooling device to the finishing mill. Through bolt connection, the cooling device can be reliably installed on the finishing mill, achieving seamless integration with existing production equipment systems. This allows the cooling device to be accurately positioned near the rolls for cooling operations and maintain a stable working position throughout the production process.

[0031] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
