The Multi Physical Fields Modeling for 7B50 Aluminum Alloy Semi-Continuous Casting Process

Abstract:

In order to understand the solidification behavior in the semi-continuous casting process of 7B50 aluminum alloy, a thermo-mechanical model for the analysis of 7B50 aluminum alloy solidification process is presented, this model considering liquid-solid phase-change effects for the solidification alloy. The thermal contact conductance between the mould wall and the ingot, the convective heat transfer coefficient are taken into account in the model. The distribution of temperature and stress in the process of semi-continuous casting of 7B50aluminum alloy are analyzed in three-dimensional finite element methods based on the above models. The variation of casting speed to influence the temperature and stress of the ingot in the process of semi-continuous casting is studied.
