Before being used, steel coils undergo a process called pickling to ensure their cleanliness. Pickling is a chemical treatment that eliminates impurities, scale, rust, and other contaminants from the surface of the coils.
Initially, the coils are immersed in an acid bath, typically containing a mixture of hydrochloric acid and sulfuric acid. This acid solution effectively dissolves any rust, scale, and impurities present on the surface. The duration of immersion varies depending on the level of contamination and the desired level of cleanliness.
After pickling, the coils undergo a thorough rinsing with water to eliminate the acid solution and any remaining residue. This step is crucial to prevent further corrosion or chemical reactions.
Once rinsed, the coils are often dried to remove any remaining moisture. This can be achieved through air drying, using high-pressure air blowers, or passing the coils through heated chambers.
After the cleaning process, the steel coils are now ready for use in various applications, such as manufacturing, construction, or any industry that requires high-quality steel products. The pickling process guarantees that the coils have a clean, smooth, and corrosion-resistant surface, enabling them to perform effectively and meet the desired specifications.
