What is pickling steel?
Pickling is an essential metal surface cleaning procedure, particularly valuable after metal forming. This process involves immersing the metal into a specialized acidic solution, referred to as the pickling liquor. The acidity level and composition of this liquor vary based on the type of metal being treated. For most low alloy steels, hydrochloric acid is the preferred choice. However, metals with high acid resistance may require either a stronger acid or a two-step pickling approach to effectively achieve the cleaning goals. This meticulous process ensures pristine surfaces and optimal preparation for further processing.
How is pickling performed?
The pickling procedure begins with an initial rinse to clear away prominent dirt and debris. Post-rinsing, the metal is submerged into a carefully formulated pickling liquor bath. Here, the acid diligently acts to cleanse the metal surface, stripping away impurities. It's crucial to monitor immersion time closely to avoid excessive acid exposure. By choosing the right pickling liquor and adhering to precise timing, surface imperfections are efficiently eliminated with minimal metal loss. After emerging from the pickling bath, the metal undergoes a secondary rinse and typically proceeds to an oiling stage, ensuring a cleaned and protected finish.
The Application of pickling steel
1,Automotive industry applications encompass vital components such as the automotive chassis system, including girders and auxiliary beams. Wheels, featuring rims and spokes, also benefit from pickling. The cockpit panel and the underbody of truck carriages are key areas of use. Additionally, the process is integral for crafting other stamping parts, such as anti-collision bumpers, brake sleeves, and various car interior components, ensuring reliability and durability.
2, Machinery industry (excluding automobiles) extensively utilizes pickled steel in textile and mining machinery, fans, and diverse general machinery. It is essential for components like compressor shells, brackets, and water heater liners. Furthermore, chemical oil drums heavily rely on this meticulous cleaning process for superior quality and performance.
3, In other sectors, pickling is applied to bicycle parts, various welded pipes, electrical cabinets, highway guardrails, supermarket and warehouse shelves, fences, iron ladders, and a myriad of stamping parts of different configurations. This versatility demonstrates its crucial role across multiple industries.
