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.

Release agent-free aluminium strip casting

A strip casting system for aluminium and/or aluminium alloys comprising a casting furnace and a revolving chill mould having a casting gap. The revolving chill mould is designed as a roll pair, roller pair, caterpillar pair or belt pair. The strip casting system has an active means for transporting metal melt from the casting furnace to the casting gap and a casting region arranged in front of the casting gap. The casting region is delimited on one side by the revolving chill mould. A melt pool is formed in the casting region, from which metal melt flows or is drawn into the casting gap. The casting furnace is connected to the casting region by a pipe system with means for feeding the metal melt into the casting region, which can feed the metal melt to the casting region below the surface of the melt pool formed in the casting region.
