Abstract

This study is to investigate the effect of electromagnetic brake (EMBr) on fluid flow and particle motion in steel slab continuous casting strands. the effect of slide gate moving on fluid flow pattern was discussed. a strong swirl and asymmetrical flow at the outports and, subsequently, inside the slab mold, was induced by slide gate. the application of EMBr would be a remedy to the swirl flow in the casting mold. Flow pattern has great influence on the trajectories of injected bubbles and nonmetallic inclusions. More bubbles tend to release from the top surface near the wide face opposite to the gate opening side without EMBr; while they escape at the center place of the slab thickness when the EMBr was applied. Local brake type EMBr has a little effect on the overall removal fraction of nonmetallic inclusions, especially for the small ones. However, EMBr affects the distribution of inclusions on the cross section of the slab, and more inclusions were observed in the sub-surface layer of the slab. © 2011 WILEY-VCH Verlag GmbH & Co.
