With the development of global economy, environmental protection and technology, wire surface treatment has also appeared in various development directions. With the increasing environmental protection requirements of various countries, acid-free treatment methods such as shot blasting and mechanical peeling have emerged one after another. However, the surface quality of the wire processed by these methods is still not as good as the effect that can be achieved by traditional pickling, and there are always various defects . Therefore, it has become an urgent need to not only achieve the surface quality of traditional pickling, but also low emissions and high efficiency. With the advancement of technology, automated pickling surface treatment equipment came into being.
