In recent years there have been many attempts to improve the productivity and applicability of Twin Roll Casters for aluminium sheet products. Several developmental strip casters were manufactured around the world to investigate Thin Strip Twin Roll Casting, and from these results we see the installation of equipment capable of casting gauges down to 2 mm. Productivity benefits have not yet been as expected, due in part to the difficulties in achieving desirable microstructures with the fast cooling rates and deformation characteristics inherent with this type of caster. The importance of selecting the correct grain refiner to optimise the microstructural properties of Twin Roll Cast aluminium alloys at all gauges and casting conditions is reviewed here.
