MODELING OF AZ80 MAGNESIUM ALLOY CASTING PROCESS UNDER DIFFERENT ELECTROMAGNETIC FREQUENCY

Yuanyuan Bai, Rufei Wei, Qichi Le, Haitao Zhang

Abstract


The paper aims to clarify the effects of electromagnetic frequency on magnesium alloy AZ80 billets during low frequency electromagnetic casting. It proposes a mathematic model, verified against the temperature measurements obtained from AZ80 alloy billet of 160 mm in diameter, to predict the interaction of electromagnetic field, fluid flow, and temperature distribution. The sump depth becomes deeper and the maximum sustained speed of melt flow increases with the increase of electromagnetic frequency. By the analysis of the effects of fluid flow and temperature field on the solidification in the presence of electromagnetic field, the best electromagnetic parameters are given.


Keywords


Low frequency electromagnetic casting; Magnesium alloy; Temperature field; Fluid flow.
