摘要

The products of hot continuous roll casting, which has the feature of being a short process, have some quality defects. In this paper, the magnetic field and current in different directions are applied on both sides of molten pool by the embedded electromagnetic casting roll, and the aluminum melt is forced to nucleate under the action of electromagnetic force with low consumption. which inhibits crystal growth and obtains fine equiaxed grain structure. Based on finite element simulation and physical simulation experiments, it is concluded that when the magnetic field and current direction on both sides of molten pool are the same, the central stirring force is generated, and complex convection is generated in the opposite direction. When the frequency is 10 Hz, the electromagnetic stirring effect is the best. Moreover, the matching and coupling relationship between electromagnetic parameters and casting temperature is studied from the perspective of macro- and microstructure of the materials.
