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.
