Abstract
In high speed pickling and other fluid treatment of metal strip, the acid or other medium is carried along with the strip, and the momentum of the treatment fluid is utilized in a flow reversal path to reverse the flow and carry the fluid on a receiving surface which directs it for recycling to the upstream end of a flow reversal zone; this procedure is repeated in at least one sequential iteration.
