Description

Technical Field

[0001] The utility model relates to the technical field of stainless steel pickling, in particular to a stainless steel pickling device. Background Art

[0002] Stainless steel pickling is a common industrial treatment method used to remove the oxide scale, welding slag and other impurities on the surface of stainless steel to achieve a clean and bright surface effect. This process usually uses an acidic solution such as nitric acid, hydrochloric acid or sulfuric acid to expose the stainless steel surface to ensure the removal of residual acidic substances and finally obtain a clean and smooth surface. Stainless steel pickling is widely used in the production and processing of various stainless steel products, including pipes, plates, profiles, etc. Through pickling, stainless steel products can meet the requirements of use.

[0003] When pickling stainless steel, the traditional pickling method is to directly immerse the stainless steel in an acidic solution for pickling, which has a poor effect and a long pickling time. Secondly, the pickling solution after pickling contains various impurities, such as welding slag, etc., which remain in the pickling solution, which is not conducive to subsequent pickling work. Finally, when pickling stainless steel, the stubborn stains or welding slag adhered to the surface of the stainless steel product are difficult to clean. Therefore, a stainless steel pickling device is proposed to address the above problems. Utility Model Content
