ABSTRACT:
A process and apparatus for removing oxides, millscale and other impurities from continuous metal strip longitudinally fed at regulated speeds from a coil at one end through a series of horizontally aligned treatment stages, including three shallow pickling tanks, to a recoiler at the other end. The pickling tanks are constructed of granite slabs formed into a V-shaped cross section near the ingress and a flat ramp near the egress. Variable speed pinch rolls at the ends of each tank regulate the immersion of the strip in the tanks.
