    • 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.
    • 在酸性溶液中用于除锈不锈钢的连续电解方法,在电解电流流动的间接效应的情况下,所述电流是DC或AC,频率低于3Hz,其特征在于阳极处理时间和电池电流 根据公式It = c + kI选择其中:I是与电池交叉的电流密度; t是阳极处理时间; c是直接氧化物改变阳极反应输出的电荷密度的恒定分数; k是与用于与水的羟基离子的氧化相关的间接阳极反应输出的电流密度I(kI)成比例的电荷量分数的计算的时间常数,一方面 在钢/电解液界面产生和保持酸化,而另一方面,它将电荷与氧化反应和氧化反应相抵消。
