| Abstract: | According to the theory of alternating magnetohydrodynamics and magnetic boundary renewal method, mathematical models were proposed for electromagnetic stirring in secondary cooling region (SEMS) of slab caster. The magnetic fields and flow fields of melt were simulated with SEMS. It′s shown that the electromagnetic forces with inward and sidelong components produced by travel magnetic field at the wide faces of slab make the melt whirling in horizontal section, and the convection of the melt is strengthened obviously there. In addition, magnetic flux density attenuates from the edge to the center of slab, and the profile of the melt velocity along slab thickness in the center of the horizontal section takes a two-opposite-peak configuration. Ultimately, the stirring intensity and features are determined by the electromagnetic parameters, coil arrangement and stirring types. |
