: In order to study the effect of the stirring flow on the grain diameter and solute concentration of hollow billet, the couple model of the two-phase solidification and electromagnetic field was built..., concentration field and grain diameter of molten metal during solidification were analysed. The results show that, there are different flow patterns in the molten metal induced by the traveling magnetic......
