ABSTRACT OF THE DISCLOSURE This invention relates to the continuous annealing of steel strips and resides in the fact that a rapid or semi-rapid quenching between the annealing treatment proper and the over- aging process is effected by dipping the slow quenched steel strip in an electrolytic pickling bath, in which the strip is first connected as a cathode to a D.C. source and the speed of quenching is controlled by regulating the current density to control the amount of hydrogen developed on its surface and thereafter is connected as an anode to a D.C. source. After the overaging process and final cooling, the steel strip may be sub- mitted to an electrolytic treatment in a sulfate-based neutral aqueous solution, preferably activated with other anions, such as borates and/or phosphates.
