What Is Push-Pull Pickling?

Push-Pull Pickling

Push-pull pickling is a process used in the steel industry to clean and prepare steel strips by removing oxide scale and other surface impurities. This method involves passing the steel strip through a series of acid baths, typically containing hydrochloric acid, in a back-and-forth motion. The push-pull technique allows for greater flexibility in processing various grades and dimensions, making it ideal for smaller batches and frequent production changes. The process ensures a clean, scale-free surface, which is essential for subsequent operations like coating or forming.
