Embodiment Construction

[0034] exist figure 1A melt dip coating system is schematically shown in , which is used for coating a strip 1 with a coating metal. In this exemplary embodiment, the strip 1 is introduced in a known manner into a coating container 2 in which a liquid coating material is contained. Currently, the deflection of the strip 1 in the vertical direction V takes place by means of deflection wheels 14 . Of course, the CVGL method can also be used, in which the strip 1 enters the coating container 2 vertically from below and the bottom opening is sealed by means of an electromagnetic closure.

[0035] After the coated strip 1 leaves the coating container 2 vertically upwards, the excess coating metal is blown off by means of the removal nozzle 3 . Above the removal nozzle 3 there is a mechanism 4 for stabilizing the strip 1 . The mechanism 4 has as a core part two electromagnets 6 arranged on both sides of the strip 1 . With this electromagnet 6 it is achieved that the strip is sel...

Abstract

The invention relates to a device for coating a metal strip (1) with a coating material, comprising a coating container (2) filled with a liquid coating material, through which or out of which the coated strip (1) is guided vertically (V) upward, wherein a stripping nozzle (3) for stripping still liquid coating material from the strip surface is arranged above the coating container (2), wherein an electromagnetic apparatus (4) for stabilizing the position of the strip (1) in a central position (5) is arranged above the stripping nozzle (3), wherein the apparatus (4) comprises two magnets (6) arranged on both sides of the metal strip (1) at the same height. In order to be able to respond in an improved and simplified manner to different requirements with respect to the strip guidance, the invention is characterized by means (7) for adjusting the vertical distance (H) of the magnets (6) from the stripping nozzle (3). The invention further relates to a method for coating a metal strip.

Description

technical field [0001] The invention relates to a device for coating a metal strip with a coating material, the device having a coating container filled with a liquid coating material The coated strip is guided vertically upwards through the coating container or out of the coating container, wherein removal nozzles (Abstreifdüse) are arranged above the coating container for removal from the strip surface (Abstreifen ) still liquid coating material, wherein an electromagnetic mechanism is arranged above the removal nozzle for stabilizing the position of the strip in an intermediate position, wherein the mechanism comprises at least two Magnets on the same height. Furthermore, the invention relates to a method for coating a metal strip with a coating material. Background technique [0002] Devices of this type and corresponding methods are known. Document DE 10 2008 039 244 A1 describes a device for melt dip coating in which a metal strip is guided through a coating bath a...
