ABSTRACT:
The device comprises an ultrasonic wave emitter (4) whose lower end portion (5) is immersed in the reactive solution (2) in which a sheet (3) to be pickled is immersed, and this end portion is provided with two emitting plates (6,7) respectively positioned on each side of an edge portion of the sheet (3) with their planar emitting surfaces parallel to the sheet and contained in two antinodal planes. Consequently, the two plates (6,7) vibrate in phase opposition and, if the vibratory amplitude is sufficiently large, these vibrations create a cavitation in the liquid in the space between the surfaces (3a,3b) of the edge portion and the plates (6,7) which considerably accelerates the rate of removal of scale from the edge portion.
