Description

Technical Field

[0001] The utility model belongs to the technical field of hot rolling roll equipment, and particularly relates to a roll cleaning device for a hot rolling titanium plate finishing mill unit. Background Art

[0002] In the field of metal strip production such as steel rolling production lines, rolling mills are widely used for deep processing of metal plates; however, under the action of rolling force, foreign matters such as metal powder, passivation film, and dust will adhere to the working roll of the rolling mill during the contact with the strip; as the rolling length increases, the adhered foreign matters gradually accumulate to form larger lumps, which will not only cause color spots and color differences on the surface of the strip steel, but also cause defects such as pits on the surface of the strip steel.

[0003] After retrieval, there is a high-efficiency cleaning device for a finishing mill unit with the prior art publication number CN 220554848 U. A scraper is installed on the surface of two finishing rolls of this device. The scraper adheres to the surface of the finishing roll. When the finishing roll rotates, the impurities adhering tightly to its surface will be scraped off by the scraper. The fallen impurities will be transmitted to the inside of the box body through the aggregation hopper, while the lighter impurities will be directly swept off by the sweeping brush, and will be adsorbed into the filter cartridge by the suction hood with negative pressure for filtration treatment; however, foreign matters such as metal chips and dust on the roll surface are mixed with the oil stain on the roll surface to form sludge. During the cleaning process by the sweeping brush, the sludge is easily attached to the sweeping brush, affecting the cleaning effect of the sweeping brush; moreover, the impurities scraped off by the scraper need to fall into the aggregation hopper from above the rolling mill. To prevent the cleaned impurities from falling onto the strip surface, the device can only clean the roll after the rolling mill stops.

[0004] After retrieval, there is a roll cleaning device for a rolling mill with the prior art publication number CN 213495659 U. This device sprays a cleaning agent on the roll surface through a water spraying component, then scrapes off the impurities adhering to the roll surface with a scraping plate, and wipes off the cleaning agent remaining on the roll surface through a wiping component; however, the cleaning agent can only contact the outermost layer of dirt, and the dirt in the inner layer can only be scraped off by the scraping plate.

[0005] Therefore, a roll cleaning device for a hot rolling titanium plate finishing mill unit is needed, which can deeply clean foreign matters such as sludge adhering to the roll under the normal operation state of the finishing mill. Summary of the Invention

[0006] The purpose of the utility model is to overcome the deficiencies in the prior art and provide a roll cleaning device for a hot rolling titanium plate finishing mill unit.
