Abstract：The numerical simulation study for the fluid flow in a slab caster mold with electromagnetic brake (EMBR) is described. The influence of operation conditions, such as magnetic flux density, port angles of nozzle and position of magnetic field, on electromagnetic braking were simulated. The numerical results show that flow field in the mold is changed largely with EMBR. And the surface velocity of molten metal in the mold was minimal at a magnetic flux density of 0.5 T, it agreed well with measured surface level fluctuations in water modeling. So it is necessary to optimize the magnetic flux density for certain casting conditions. When the magnetic flux density, the casting speed and the port angles of nozzle are certain, there is an optimal ratio of the location of magnetic field to the immersion depth of nozzle. With such optimal ratio, the effect of electromagnetic brake is the best.
