Abstract
A casting roller or belt for a revolving chill mould of a strip casting system is provided for the manufacture of an aluminium alloy strip. The strip casting system for manufacturing the aluminium alloy strip includes at least one such revolving chill mould with a casting gap. In the casting roller or belt of the strip casting system, adhesion to the casting roller or belt is avoided during strip casting, and a low-segregation and crack-free aluminium alloy strip can be produced under industrial conditions. This is achieved by utilizing a specific surface structure of the casting roller or belt in which a roughness value Sa is more than 5 μm and an average peak count RPc (0.5 μm) is less than 42 cm.
