Description

Technical Field

[0001] This application relates to the field of cooling devices for cold rolling mills, and in particular to a jet cooling device for cold rolling mills. Background Technology

[0002] Cold rolling is an important process in the field of metal material processing, and it is widely used in the precision forming of products such as plates and strips. During the cold rolling process, the metal plate undergoes plastic deformation under the high pressure of the rolls, which generates a large amount of frictional heat and deformation heat, resulting in a significant increase in the temperature of the rolls and the plate. Therefore, efficient and precise cooling devices have become an indispensable part of cold rolling equipment.

[0003] Traditional cold rolling mill cooling technology mostly adopts a fixed spray system, which sprays coolant onto the surface of the rolls or sheet through nozzles to achieve cooling. However, this design has certain drawbacks in practical applications. First, the spray range is usually a fixed structure and cannot be adjusted according to the width of the sheet being processed. When processing narrower sheets, a large amount of coolant is sprayed into non-processing areas, resulting in resource waste and environmental pollution. When dealing with wider sheets, the edge areas may experience localized overheating due to insufficient cooling coverage, affecting the uniformity of rolling.

[0004] In other words, existing technologies have the following technical problems: the spray range of conventional cold rolling mill cooling technology cannot be quickly adjusted according to the width of the processed sheet. Therefore, a spray cooling device for cold rolling mills is proposed to address the above problems. Summary of the Invention

[0005] This embodiment provides a spray cooling device for a cold rolling mill to solve the problem that the spray range of ordinary cold rolling mill cooling technology in the prior art cannot be quickly adjusted according to the width of the processed sheet.
