Description

A cleaning device for cold rolling mill working rolls

Technical Field

The present application relates to the technical field of cold rolling mills, and in particular to a working roll cleaning device for a cold rolling mill.

Background Art

The cold rolling mill is a new type of steel bar cold rolling processing equipment. The machine can process hot-rolled wire rods or hot-rolled coils into cold-rolled ribbed steel bars. During the operation of the cold rolling mill, due to the deformation of the processed metal, some iron filings and other impurities cannot be avoided from sticking to the cold rolling rollers. If the working rollers of the cold rolling mill are not cleaned, these iron filings will affect the rolling accuracy and quality of the rolled products when the cold rolling mill is working. In serious cases, it may affect the overall operation of the cold rolling mill.
