A device for coating a metal strip substrate includes a guiding apparatus for guiding the strip substrate along a movement path. A first coating apparatus coats a first main side of the strip substrate with an electrostatically charged coating powder which is in a fluidized state. The first coating apparatus is arranged under a first path section of the movement path. A second coating apparatus coats a second main side of the strip substrate with an electrostatically charged coating powder which is in a fluidized state. A redirecting unit redirects the strip substrate between the first and the second coating apparatus in such a way that the strip substrate in a second path section travels oppositely to the strip substrate in the first path section. The second coating apparatus is arranged at least partly geodetically under the second path section.

Device and method for coating of a metallic strip substrate on one side and/or on both sides

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.

Method and device for descaling a metal strip

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.
