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.
