Abstract

Es wird ein Verfahren sowie eine Anlage zur Oberflächenbehandlung vorgeschlagen, bei dem in einem ersten Schritt das Walzgut (6) unmittelbar nach dem letzten Verformungsschritt in der Walzstraße (1) homogen über Walzgutbreite und -länge auf eine Temperatur abgekühlt wird, bei der eine Zunderbildung des Walzgutes eingeschränkt oder unterdrückt ist, und bei dem in einem zweiten Schritt das gegebenenfalls schwach verzunderte Walzgut zur vollständigen Entzunderung seiner Oberfläche sowie gleichzeitig zur Einstellung gewünschter mechanischer Eigenschaften einer Glühung unter reduzierenden Bedingungen unterworfen wird. Auf diese Weise wird ein Warmband mit sehr guter Oberflächenqualität bei gleichzeitig guten mechanischen Eigenschaften erzeugt.
