Summary

The single-roll strip casting process is simulated with FLOW-3D® to determine the influence of key process parameters on the solidified aluminium strip. The input variable involving the heat transfer coefficient is obtained from experiments. The results of the simulations were verified by casting experiments on the single-roll strip caster. The process parameters involve hydrostatic pressure, wheel velocity, casting temperature and gap distance. Also we have investigated the influence of alloy composition and casting temperature on the as-cast microstructure of the strip. The composition of the AlMnMg-alloy is varied with minor additions of Fe, Cr, and Si. These additions affect the morphology of the intermetallics and the casting temperature affects the size of the intermetallics. The size of the intermetallics becomes smaller with a higher casting temperature. The equiaxed grain size is also affected by casting temperature. The length of the columnar zone for the various alloys is similar when casting takes place at liquidus temperature and varies at a higher casting temperature.
