Description

Polishing scrap collecting device and acid rolling line Technical Field The application belongs to the technical field of acid washing, and particularly relates to a polishing chip collecting device and an acid rolling line. Background The acid rolling line has extremely high requirements on the product quality, the surface of the strip steel is often required to be checked at the position of a quality inspection chamber of an acid washing section, and if defects are found to be polished, the strip steel is prevented from being broken and the quality problem of punch marks in the subsequent cold rolling process. In order to facilitate the surface inspection of the strip steel, the strip steel vertically runs in the inspection polishing section and horizontally runs in the subsequent cold rolling section, so that a steering roller is required to be arranged between the polishing section and the cold rolling section to change the vertical running of the strip steel into the horizontal running. The scraps formed after polishing the strip steel in the polishing section can move downwards to fall on the steering roller, and as the steering roller is a rubber roller, the scraps on the steering roller are adhered to the rubber roller after extrusion of the strip steel, and secondary damage is generated to the strip steel.
