Abstract:In order to investigate the magnetic force distribution, flow field distribution and temperature field distribution during continuous casting process of Al/Al bimetal round billet under multi-electromagnetic fields, a comprehensive mathematical model has been developed. The model is based on a combination of the commercial finite element package ANSYS and the commercial finite volume package FLUENT, with the former for calculation of the multi-electromagnetic fields and the latter for calculation of the magnetic driven fluid flow, heat transfer, temperature field and solidification. There was a good agreement between the calculate results and the experiment results. Comparison of the calculated results of the continuous casting process without electromagnetic with that of the continuous casting process under multi-electromagnetic fields indicated that velocity patterns, temperature profiles and the sump depth are modified remarkably by the application of multi-electromagnetic field during the continuous casting process.
