Description

Technical Field

[0001] This utility model relates to the field of steel plate processing technology, and in particular to a steel plate flattening device for a four-roller leveling machine. Background Technology

[0002] Steel plates are an indispensable practical material in modern industry. In the production and processing of steel plates, a high degree of flatness is required to meet the needs of practical applications. Therefore, it is necessary to perform a leveling operation on the steel plates.

[0003] In modern industrial production, the flattening of steel plates by a four-roll leveler is a crucial process for ensuring plate quality. At the start of the operation, the steel plate is smoothly fed between the upper and lower sets of rollers on the leveler. These two sets of rollers have a clear division of labor: the smaller-diameter, smooth-surfaced work rollers directly contact the steel plate, while the larger-diameter support rollers provide solid support for the work rollers, effectively enhancing their rigidity. As the motor starts, the work rollers and support rollers begin to rotate synchronously. The hydraulic system precisely controls the reduction of the work rollers according to the material and specifications of the steel plate, so that the rolling force is evenly applied to the surface of the steel plate. Under the action of strong rolling force, the steel plate undergoes elasto-plastic deformation, with the surface metal undergoing plastic flow and the interior undergoing elastic deformation. It is in this process that the original plate shape defects such as waviness and warping are gradually eliminated, the surface becomes flat and smooth, and its roughness is significantly improved, meeting the standards required for production.

[0004] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: Under the influence of external factors, the surface of existing steel plates may produce iron oxide scale and iron oxide powder, or some dust may adhere to the surface during transportation. If these substances are not effectively removed, they will not only embed into the surface of the steel plate during leveling operations, forming defects such as indentations and scratches, but also aggravate the wear of the work roll and support roll, resulting in a decrease in roll surface accuracy. Utility Model Content

[0005] The technical problem to be solved by this utility model is that the existing technology does not have a corresponding cleaning structure, so if the dust and other substances attached to the surface of the steel plate are not effectively removed, they will affect the final flattening quality of the steel plate.
