Abstract
In this article, the impact of an electromagnetic brake (EMBr) on the flow pattern in a continuous casting mold was simulated with an implemented Reynolds-averaged Navier-Stokes (RANS) SST k-ω turbulence model. A new type of EMBr, named vertical electromagnetic brake (V-EMBr) was introduced to investigate its applicability and adaptability. The characteristics of electromagnetic field and flow field inside a 1450 mm × 230 mm mold with V-EMBr have been simulated. The numerical simulation results indicate that the static magnetic field generated by V-EMBr can cover both the vicinity of the mold narrow faces and the impingement region of jet flow, which can effectively control the liquid steel flow in the upper recirculation zone. The parametric study also shows that the braking effect on the surface velocity and steel/slag interface fluctuation is enhanced when the magnetic pole is placed close to the narrow face of the mold.
