Abstract:
The Electromagnetic Stirring has been shown to be useful in the quality of solidification structures, inhibiting the formation of columnar structures, promoting the solute redistribution and defects attenuation through electromagnetic forces induced in the liquid phase. Based on the design of M-EMS of a billet-casting machine, simulations of fluid flow (CFD) and temperature under influence of electromagnetic field were performed. As a second aim, the stirrer effect on the inclusion trajectory and how it could promote the subsurface quality of the solidified structures was evaluated. Different frequencies and current of M-EMS, as well nozzles geometries, were tested. The results showed the tendency displacement of the particle, the fraction of solid particles removed from domain and the influence of M-EMS in the heat extraction from the mold, improving the temperature distribution during the solidification process.
