Abstract (en)
[origin: WO8605523A1] A method for pickling iron or steel objects before a subsequent surface treatment or mechanical processing. The objects (11) are transported into a pickling bath (10) having a temperature above 25<o>C and containing a solution of ferrous chloride and a low proportion of free hydrochloric acid. The pickling bath is continuously regenerated in a circulation system with electrolytic cells (14). These are preferably electrically connected in series and in parallel with the flow of the pickling bath, in order to deposit iron on the cathode (19) and recover free acid.
