Numerical Simulation on the Process of Al-Alloy Air Cushion Continuous Casting

Abstract:

According to the characteristics of solidification process of air cushion continuous casting, and on the basis of continuum model for binary solid-liquid phase change system, a set of equations which include continuity, momentum conservation, energy conservation and solute conservation ones are established. Furthermore, a coupled solution method of the set of equations, in which controlled-volume finite difference method is used and developed. The effects of some typical parameters such as billet diameter, casting speed and the second cooling on the solidification behavior are studied, and some meaningful results, which are significant to the technique optimizing of the air cushion continuous casting, are obtained.
