Roller descaling device

Abstract

The invention discloses a roller descaling device which uses a mechanical structure to remove matters adhered to the surface of a roller and can improve the descaling effect of the roller. The roller descaling device comprises a brush handle and bristles arranged on the brush handle. The bristles act on the outer surface of the roller. When the roller rotates to work, as the bristles act on the outer surface of the roller, foreign matters adhered to the roller can be automatically removed by the bristles in the rolling process of the roller so that the descaling effect can be improved, thereby ensuring the quality of a rolled element and preventing backedge defect of the rolled element. The device breaks a conventional mindset, effectively removes the foreign matters adhered to the hole-shaped surface of the roller by causing the bristles to directly contact the outer surface of the roller and adopting a mechanical removing method, and effectively solves the problem that the matters adhered in the hole-shaped area of the roller are pressed into a rolled element to cause the backedge defect; and the device is particularly suitable to be generalized in the use of various rolling mills.

Description

technical field [0001] The invention relates to a roll descaling device, in particular to a roll descaling device which adopts a mechanical structure to remove adherents on the roll surface. Background technique [0002] At present, when hot rolling is used to manufacture steel profiles, due to the adhesion of foreign matter such as scale, metal blocks, and burrs on the surface of the billet to the pass surface of the vertical roll, periodic pits will be pressed out on the surface of the rolled piece to form rolling scar defects. , leading to a large number of bad products, resulting in a large amount of waste of materials and production capacity. In order to avoid this waste and improve the yield, the pass area of ​​the vertical roll must be cleaned and descaled before hot rolling (i.e. the adhesion on the roll surface). [0003] In the existing descaling methods, in order to avoid secondary scratches on the pass surface of the roll, mechanical descaling is excluded in the...

AI Technical Summary

Problems solved by technology

[0003] In the existing descaling methods, in order to avoid secondary scratches on the pass surface of the roll, mechanical descaling is excluded in the conventional thinking and actual operation for the descaling of the pass of the vertical roll. Scaling device is possible, and high-pressure water or air is used to carry out non-mechanical purging and descaling (with periodic purging) on ​​the hole surface of the vertical roll, but the descaling effect is not ideal, which often causes rolling scar defects on the section steel
