A continuous electrolytic method in an acid solution for the descaling of stainless steels, in the presence of electrolysis current flow indirect effects, said current being DC or AC, with a frequency lower than 3 Hz characterised in that the anodic treatment times and the cell currents are selected according to the formula It = c + kI where: I is the current density crossing the cell; t is the anodic treatment time; c is the constant fraction of electric charge density outputted for the direct oxide changing anodic reactions; and k is a time constant for the calculation of the fraction of electric charge quantity, proportional to the current density I (kI), outputted for the indirect anodic reaction linked to the oxidation of the hydroxyl ions of the water, that on the one hand produces and maintains the acidification at the steel/electrolytic solution interface, whereas on the other hand it substracts electric charges to the oxidation reactions of the scale and of the underlying metal. |
