Description

Technical Field

[0001] The utility model relates to the technical field of stainless steel casting processing, in particular to chemical polishing equipment for preparing stainless steel castings. Background Art

[0002] Chemical polishing is a method of eliminating wear marks and etching and leveling the uneven areas of the sample surface by the chemical etching of chemical reagents. Chemical polishing can be used as a pretreatment process for electroplating, or it can be used directly after polishing with the necessary protective measures. Some stainless steel castings need to be chemically polished during production and processing. At present, stainless steel castings are generally placed in containers filled with chemical reagents for etching. The chemical reagents inside the container are stationary, so the polishing effect is not very good. Some impurities on the surface of the stainless steel castings may not be well detached. Therefore, we propose a chemical polishing equipment for preparing stainless steel castings to solve the above problems. Utility Model Content
