Abstract The slab size can strongly affect the effect of electromagnetic brake (EMBr). Aiming at the compact strip production (CSP) funnel-type mold in the industry, a three-dimensional mathematical model was developed to describe the process of EMBr in the funnel-type mold. The results show that, the EMBr can raise the location of the vortices and make the lower recirculation zone smaller; the EMBr results in obvious reduction of horizontal velocity and the level fluctuation at the meniscus region, at the same time, increase the meniscus temperature; at the mold exit, the EMBr causes slightly more uniform shell growth of wide face and a slightly increase of the solidified shell thickness of narrow face; with the increase of the slab width, the effect of EMBr becomes not obvious.
