Technical Field

[0001] This utility model relates to the field of metal processing technology, and specifically to an acid pickling device for metal surface treatment. Background Art

[0002] Pickling is a method of removing oxide scale and rust from the surface of steel using acid solutions. Generally, the workpiece is immersed in an aqueous solution of sulfuric acid or the like to remove thin films of oxides from the metal surface. It is a pretreatment or intermediate treatment for processes such as electroplating, enamel, and rolling.

[0003] Existing pickling equipment often involves directly placing the metal products to be pickled into the pickling tank. However, during the entire cleaning process, the lack of water flow impact prevents some impurities from being removed from the surface of the metal products, thus affecting the pickling effect. Therefore, we propose a pickling device for metal surface treatment. Utility Model Content
