Description

Technical Field

[0001] The utility model relates to the technical field of metal processing, in particular to a roller rapid cooling device. Background Art

[0002] The metal rolling process is a process in which metal billets are processed into the desired shape and size by extrusion and plastic deformation through a series of rolling mills and rollers. During the rolling process, the rollers are subjected to high temperatures and high pressures, which may cause changes in the surface and structure of the rollers, and even affect the service life and processing quality of the rollers. Therefore, in order to ensure the stability and long-term reliability of the rollers, some measures need to be taken to control the temperature of the rollers and ensure that they can maintain an appropriate temperature range during operation.

[0003] After searching, the existing Chinese patent announcement number is: CN217528695U, which discloses a rust-free rapid cooling device for high-speed steel rolls, relates to the technical field of roll cooling, and solves the technical problem in the related technology that the water cooling group is rusted, while the air cooling has poor cooling effect. The device includes a cooling medium storage box, an upper spray cooling manifold, a cooling medium recovery box and a temperature controller. The cooling medium storage box is provided with cooling medium, the upper spray cooling manifold is provided with nozzles arranged in rows, the nozzles are connected to the cooling medium storage box, and the nozzles are all arranged toward the rolls. The cooling medium recovery box is arranged below the upper spray cooling manifold, and the cooling medium recovery box is also provided with a return pipe connected to the cooling medium storage box. The rolls are arranged inside or above the cooling medium recovery box, and the temperature controller is used to control the temperature of the cooling medium in the cooling medium storage box. That is, it ensures that the water-cooled rolls will not rust on the surface, and has the advantage of rapid water cooling, which is particularly suitable for rapid cooling of high-speed steel working rolls of finishing mills when they are repeatedly used on the machine.

[0004] The above patent mentioned in the specification that "the upper spray cooling manifold 200 includes two parallel rows of nozzles 210, and the arrangement direction of the nozzles 210 is consistent with the axial direction of the roller 20. The two rows of nozzles 210 are respectively arranged on the left and right sides of the vertical symmetry plane of the roller 20. Considering that one row of nozzles 210 cannot achieve 360° flushing and cooling of the entire circumference of the roller 20, two rows of nozzles 210, one on the left and one on the right, are arranged to flush and cool the entire circumference of the roller 20 360°, thereby improving the cooling effect". However, in the actual use process, it cannot be moved when cooling the roller, which will result in uneven cooling area when cooling the roller, and at the same time cause a large amount of water resources to be wasted, increasing the cost of use.
