Description

Technical Field

[0001] The utility model relates to the technical field of rust removal and maintenance devices, in particular to a rust removal and maintenance device for cold-rolled strip steel. Background Art

[0002] Cold-rolled strip steel refers to hot-rolled strip steel and steel plate as raw materials, which are rolled into strip steel and thin plates by cold rolling mill at room temperature. In the cold-rolled strip steel production line, since the steel strip is an oxidizable metal, it is produced in the air and exposed to the air. When it comes into contact with oxygen, it will form oxide scale, which is the usual rust. Although the degree of this type of oxide scale is less, it will also affect the quality of the cold-rolled strip steel.

[0003] Usually, when cold-rolled steel strip is sold as a finished product, in order to improve the quality of the cold-rolled steel strip, it is necessary to first perform rust removal on the cold-rolled steel strip. A steel plate immersion rust removal device with a search publication number of CN213266704U is disclosed. By setting a card slot, a card block filter, a filter frame and a filter, the iron filings that fall off when the steel plate is immersed in the steel plate immersion box can fall on the top of the filter, which is convenient for cleaning the iron filings. However, in this new practical method, the steel plate is placed in a curing pool and the steel plate is in a static state. The iron filings on the surface of the steel plate will still adhere to the surface after falling off, and further cleaning is required. At the same time, after the steel plate is derusted, a large amount of pickling liquid will adhere to the surface of the steel plate, and the steel plate cannot be dried quickly. Therefore, a cold-rolled steel strip rust removal and curing device is proposed. Utility Model Content
