An approach for continuous casting of molten metals with vertically flexible edge containment is disclosed. A vertically flexible edge containment device can confine molten metal in a moving mold cavity of a continuous metal casting apparatus. In operation, the vertically flexible edge containment device is configured to flex in a vertical direction relative to a flow of the molten metal in the moving mold cavity. The flex in the vertical direction of the vertically flexible edge containment device corresponds with changes in one of a thickness and height of the molten metal in the moving mold cavity as the molten metal travels from an upstream mold region to a downstream mold region before leaving an exit end of the moving mold cavity.

A method of texturizing a casting mold of a continuous belt casting system includes providing at least one endless belt having an elongated belt surface. The elongated belt surface includes at least a first region and at least a second region adjacent to the first region across a width of the elongated belt surface, and the elongated belt surface is configured to at least partially define a casting cavity of the continuous belt casting system. The method includes texturizing the elongated belt surface by applying a predetermined texture to the first region.

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 m and an average peak count RPc (0.5 m) is less than 42 cm.sup.1.
