  • Process and apparatus for continuous surface treatment
    Patent number: 5716455
    Abstract: 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.
