Abstract

Aluminum alloys melting plays a critical role in casing production.And the melting quality controls the performance of the casings.The heat transfer behaviors in induction melting process of aluminum alloys may be helpful for better controlling melting processing parameters and obtaining better aluminum alloy melt quality.A mathematical model of coupling electromagnetic and temperature field in induction melting process of aluminum alloys was built up.The numerical solution based on finite difference method（FDM）was given

and a self-developed program was made to visualize 3D melting heat transfer behavior in aluminum alloys induction melting process.In addition

effects of different electromagnetic parameters on melting heat transfer behavior were described.
