A transient three-dimensional model is established to understand the formation of the macrosegregation induced by the magnetohydrodynamic thermosolutal convection in the electroslag remelting ingot. The solution of the mass, momentum, energy, and species conservation equations are simultaneously implemented by the finite volume method with full coupling of the Joule heating and Lorentz force through solving the Maxwell’s equations. The volume of fluid technique is used to account for the two-phase flow. The solute transport during the solidification is described by the multicomponent continuum model. Two nondimensional criterions are proposed to distinguish the effects of the Lorentz force, the thermal and solutal buoyancies on the metal flow. A reasonable agreement is obtained between the experiment and simulation. The macrosegregation pattern of Ni is demonstrated in the discussions, and moreover the impact of the current on the solute movement is clarified.
