Abstract
A pickling tank for the continuous treatment of a steel strip includes a pickling trough and a recovery tank separated from one another by a linkage that allows for limited movement between the trough and recovery tank. The recovery tank includes a pair of press rollers to remove pickling solution from the steel strip. The linkage includes a chute extending from the trough to the recovery tank to contain the pickling solution while allowing for differences between thermal expansion between the pickling trough and recovery tank. In one embodiment, the chute is coupled to the pickling trough and has a free end inserted into the recovery tank. In a second embodiment, the chute includes two telescoping members extending between the trough and recovery tank.
