摘要： 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.

摘要： Process and apparatus for the continuous electrolytic treatment and/or coating of a moving metallic strip while changing the spacing between the strip and at least one electrode as a function of deviations (distortions) of the strip normal to the direction of movement of the strip in order to automatically maintain an optimal spacing so as to keep the voltage drop in the electrolyte low and save energy. For that purpose feeler means are provided to determine the deviation and generate a first signal. A second signal is generated as a function of the velocity of the strip. The period from the moment of detecting the deviation to the moment of its arrival at the electrode, reduced by the response period for changing the spacing, is computed. The period needed for passing through the electrode is computed. The first signal is broadened at its maximum value in terms of time as a function of the length of the electrode(s) and of the second signal, and the spacing between the strip and the electrode is adjusted at the correct time and for the period of passage of the deviating portion of the strip as a function of the determined and computed data.

摘要： A process for continuous surface treatment, in particular for pickling and cleaning of metal strip in a treatment chamber through which the strip runs in a roughly horizontal path and to which a treatment liquid, in particular pickling liquid, is fed. An increased local shearing force is applied between the surface to be treated and the treatment liquid, by passing the strip through a constriction. In addition the invention is directed to a device for implementation of the process, characterized by, in particular, several processing stations such as venturi modules being provided in the treatment chamber which cause an increase in the shearing force between the strip and the treatment liquid.
