The descaling of hot strips of carbon steel is normally achieved in pickling lines consisting of many processing tanks where the steel strip comes into contact with a corrosive solution, normally hydrochloric acid. The acid reacts with the oxide layer. Iron chlorides and iron ions are dissolved into the acid baths. Maintaining the baths with fresh acid and discharging the exhaust solution maintains the processing capability of the line. In most cases, the pickling line is coupled with an Acid Regeneration Plant (ARP), which regenerates the exhaust solution by removing the iron content, thus reducing the consumption of fresh acid.
Usually, the scale thickness is 10 to 20 μm. Its so-called scale structure is not uniform, but mainly consists of a layer of wustite (FeO). According to the descaling model described by Frisch and Thiele (see Gruchot et al., 2001), the acid penetrates the scale structure, thus reaching the free metal surface. The reaction occurring between acid and free metal generates a local current flowing from the scale-free metal portion, acting as an anode, to the conductive wustite layer, playing the role of a cathode
