Abstract
In a process and plant for pickling steel strip, a highly refined steel strip is delivered in the form of a coil, uncoiled by an uncoiling hasp 1 and advanced through at least one predescaling plant 3, pickling sections and a rinsing plant 7 to a recoiling hasp 9 or a transverse cutting plant. The strip is clamped to the recoiling hasp 9 ,--,--; recoiled and drawn solely thereby or in conjunction with other driven treatment rolls through the treatment plant or is cut into sheets by the transverse cutting plant. The plant comprises at least one elongated, preferably shallow pickling vat having a supporting structure of steel, glass fibre reinforced synthetic resin or polypropylene and a lining of acid and abrasion resistant material including PVC, carbon bricks, graphite filled and/or aluminium oxide filled polyester resin.
