Abstract

PURPOSE:To adjust the immersion length of a strip in an acid liquid as desired and to permit the selection of descaling time according to scale characteristics by respectively providing dip rolls between deflector rolls on the inlet and outlet sides of a pickling tank and making one of the dip rolls movable upward and downward. CONSTITUTION:The deflector rolls 2 are respectively provided to the inlet side and outlet side of plural units of juxtaposed pickling tanks 1 and the dip rolls 3 to immerse and support the strip 4 in the acid liquid 5 are respectively provided between the deflector rolls 2. One of the rolls 3 is made movable upward and downward by a lifting device 6 via bearings 8. The immersion length of the strip 4 in the acid liquid can be consequently adjusted to lA, lB, lC when the one roll 3 is brought to the respective positions A, B, C by the device 6. The descaling time is thereby made selectable according to scale characteristics and the pickled strip 4 having excellent surface quality is obtd.
