Abstract In this paper, the state of the art of numerical simulation of magneto-hydro dynamics (MHD) in the continuous casting (CC) process is reviewed. A new numerical approach for solving the low-frequency MHD is introduced and its applications in the In-mold rotary electromagnetic stirring for a bloom caster, the electromagnetic braking for a CSP thin slab caster and the In-roll type S-EMS for a slab caster are given. The mathematical approach includes an electromagnetic model and a flow analysis model. The magnetic induction equation is used to account for the coupling between the flow model and the magnetic field model. The results show that the proposed approach can be used to describe the three-dimensional electromagnetic field distribution and the electromagnetically driven flow characteristics in the CC process and optimize the stirring and operation parameters. Finally, the future tendency of numerical simulation of magneto-hydro dynamics in the continuous casting process is suggested.
