Description

Roller surface foreign matter treatment device of handheld cold rolling unit

Technical Field

The utility model relates to the technical field of cold rolling, in particular to a device for treating foreign matters on the surface of a roller of a handheld cold rolling unit.

Background

In the production process of acid rolling, continuous annealing and galvanization in the cold rolling process, if the strip steel has impurities or foreign matters are adhered to the surfaces of rollers (such as cold rolling steering rollers or tension rollers) and the like, periodic roller punch mark defects can be generated on the surfaces of the steel plates. As the cold rolling unit is a continuous production unit, the longer the processing time is for the problem of causing the rolling mark defect, the more defective products are produced, namely the lower the rolling yield is. Because the rollers are wrapped by the strip steel, some rollers in the cold rolling continuous unit cannot remove foreign matters by adopting an automatic scraper, and the space for manually processing the foreign matters on the surfaces of the rollers is smaller, so that the rollers are difficult to process. When the similar problems are treated in the past, the rollers for generating the punch marks are firstly searched, and then the rolling mill production line is stopped for treatment by maintenance personnel, so that not only is the great safety risk brought to the operation personnel, but also the production efficiency of the continuous rolling unit is directly reduced due to the stop treatment, and waste products are generated when the cold rolling unit is stopped and started, so that great economic loss can be caused.
