Abstract: A method for descaling a metal strip, in which the metal strip is guided in a direction of conveyance through at least two plasma descaling units, in which it is subjected to a plasma descaling, where the plasma descaling is followed directly or indirectly by an operation in which the metal strip is coated with a coating metal by hot dip galvanizing of the metal strip. The metal strip is coated with the coating metal by a vertical passage process. The coating metal is retained as a coating bath in a coating tank by an electromagnetic seal. The metal strip preheated by the plasma descaling is guided, without exposure to air, from the plasma descaling into a protective gas atmosphere of a continuous furnace necessary for the coating.

Abstract: A method and a device for descaling a metal strip, in which the metal strip is guided in a direction of conveyance through at least one plasma descaling unit in which it is subjected to a plasma descaling. The metal strip is subjected to an automatically controlled cooling process in a cooling unit following the plasma descaling in the one or more plasma descaling units in such a way that it has a well-defined temperature downstream of the cooling unit.

Abstract: The present invention relates to an apparatus for hot-dip coating of a metal strand, in particular a steel strip, in which the metal strand (1) passes vertically through a vessel containing a melted coating metal (2) and an upstream guide channel (4) in a region of which at least two inductors (5) for producing an electromagnetic field are arranged on both sides of the metal strand (1) for retaining the coating metal (2) in the vessel and an increased volume of the coating metal (2) is available in at least one section (4a). For killing the coating metal bath, according to the invention, the increased volume is provided in a region of the magnetic field of the inductors (5).
