Abstract Scope |
A three-dimensional numerical model coupling the electromagnetic field, fluid flow and level fluctuation has been developed to investigate the flow behavior of molten steel in the Interstitial-Free (IF) slab continuous casting mold. According to the industrial and modeling results, the electromagnetic force (EMF) generates the swirls on the cross section and its number is corresponding to the magnetic pole pairs of electromagnetic fields. With the increase in current frequency, the EMF reaches the maximum at the current frequency of 4.5 Hz and then gradually decreases. When the current intensity changes from the 0A to the 600A, the blocking rate of slag entrapment decreases by 6.37%, but it increased 5.81% when the current intensity continues to increase to 650A. It suggests that the optimized current intensity of mold-electromagnetic stirring (M-EMS) can effectively prevent surface or subsurface defects for clean steel production. |
