Abstract

Abstract:

A mathematical model that couples electromagnetic field, flow field and temperature field is established to study round billet secondary cooling zone under pulse magneto-oscillation pulse magneto oscillation (PMO) using the finite element analysis software ANSYS. Billet internal magnetic flux density, electromagnetic force and Joule heat distribution are analyzed. Distribution of the flow field and temperature field are obtained according to the coupling electromagnetic force and Joule heat. The results show that an upper and lower recirculation zone is formed since a driving electromagnetic force is generated by pulse magneto-oscillation. The flow can reduce billet center temperature. As a result, the internal temperature distribution becomes more uniform, which is beneficial to grain refinement.

Key words: round billet, pulsed magneto-oscillation, electromagnetic field, flow field, temperature field, numerical simulation
