Abstract

Die Erfindung betrifft ein Verfahren zur Verbesserung der Ober­ flächenbeschaffenheit von Stahlblechen, die einen Korrosionsüber­ zug aus einer Aluminium-Zink-Legierung haben. Erfahrungsgemäß ist die Oberfläche dieser Bleche nicht einheitlich, so daß eine gleichmäßige anschließende Beschichtung nicht ohne weiteres durch­ zuführen ist. Um die Oberfläche jedoch so weit zu vereinheitli­ chen, daß eine Beschichtung durchgeführt werden kann, wird in den noch nicht erstarrten Überzug Zinkstaub geblasen, der das Aufkom­ men einer Strukturausbildung unterbindet. The invention relates to a method for improving the upper Surface quality of steel sheets that have a corrosion overlay have an aluminum-zinc alloy. Experience has shown the surface of these sheets is not uniform, so that a even subsequent coating is not easy is to be fed. However, to unify the surface so far Chen that a coating can be carried out is in the not yet solidified coating blown zinc dust, which the advent prevent structural training.
