Simulation of microstructures in solidification of aluminum twin-roll continuous casting

Based on the research on the solidification of twin-roll continuous casting aluminum thin strip, the analytical model of heterogeneous nucleation, the growth kinetics of tip (KGT) and columnar dendrite transformation to equiaxed dendrite (CET) of twin-roll continuous casting aluminum thin strip solidification are established by means of the principle of metal solidification. The foundation for the emulational simulation of twin-roll casting thin strip solidification structure is laid. Meanwhile has confirmed the mathematical simulation feasibility by using the Solidification Process of Twin-roll Continuous Casting aluminum Thin Strip.
