Pickling lines eliminate oxide and scale from the band surface on hot rolled coils. The process is based on passing the band through hydrochloric baths which dissolve the surface oxides like ferric oxide Fe2O3, ferrous oxide FeO, and ferric-ferrous oxide Fe3O4. The pickling process efficiency largely depends on the material chemical composition, bath temperature, removal of the same, acid concentration and tank length.
