Abstract
Description
technical field
[0001] The invention relates to the technical field of cold-rolled steel production, in particular to a high-efficiency cold-rolled steel pickling device for cutting edge production. Background technique
[0002] Pickling is an important link in the production process of cold-rolled steel strips. Pickling is the process of removing the oxide scale on the metal surface by chemical methods. Hydrochloric acid is usually used, so it is also called chemical pickling.
[0003] At present, after the steel strip is produced, it is necessary to pickle the steel strip through a pickling device. During the pickling process of the steel strip, a large amount of colored oxides will be produced, and these oxides will be mixed in the acid solution. The existing The pickling device does not have the function of filtering the acid liquid. If the oxides in the acid liquid are not filtered and removed for a long time, the purity of the acid liquid will be reduced, thereby reduc...
