Description

Technical Field

[0001] The present application relates to the technical field of cold-rolled steel pickling, and in particular to a cold-rolled steel strip pickling device. Background Art

[0002] Cold rolled steel is steel produced by cold rolling. Cold rolling is to further thin the No.1 steel plate to the target thickness at room temperature. Compared with hot rolled steel plates, cold rolled steel plates have more precise thickness, smooth and beautiful surface, and various excellent mechanical properties, especially in terms of processing performance. Because the cold rolled original coil is relatively brittle and hard, it is not suitable for processing, so cold rolled steel plates are usually required to be annealed, pickled and surface leveled before being delivered to customers. The maximum thickness of cold rolling is 0.1--8.0MM or less. For example, the thickness of cold rolled steel plates in most factories is less than 4.5MM; the minimum thickness and width are determined according to the equipment capacity and market demand of each factory.

[0003] When pickling the existing cold-rolled steel, the cold-rolled steel is basically placed in a pickling box for pickling. However, when the cold-rolled steel is rolled, there will be some iron filings on its surface. Therefore, if the cold-rolled steel is directly placed in the pickling box, the iron filings will remain in the pickling box, causing blockage inside the pickling box, which is inconvenient for pickling the cold-rolled steel. Therefore, there are shortcomings. Utility Model Content
