VERFAHREN UND VORRICHTUNG ZUM KONTINUIERLICHEN GLUEHEN VON STAHLBAENDER

This invention relates to the continuous annealing of moving steel strips. A rapid quenching between the annealing treatment and the overaging process is effected in an electrolytic pickling bath, in which the steel strip acts first as a cathode and thereafter as an anode.

Beschreibung
Zusammenfassung:	This invention relates to the continuous annealing of moving steel strips. A rapid quenching between the annealing treatment and the overaging process is effected in an electrolytic pickling bath, in which the steel strip acts first as a cathode and thereafter as an anode. The current density applied to the steel strip acting as a cathode in the electrolytic pickling bath is regulated so as to control the amount of hydrogen developed on the strip surface and, concurrently, to control the quenching speed of said steel strip.
