Influences of the Braking Effect of Ruler EMBr on Molten Steel Flow and Steel–Slag Interface Fluctuation in a Continuous Casting Mold

Electromagnetic braking (EMBr) technology, as one of the most effective technologies in continuous casting process, provides an tool for improving internal and external defects steel products. Specifically, EMBr technology takes benefit generation Lorentz force to decrease flow instability, mold powder entrapment, surface defects, if applied properly. For this purpose, gain a clear understanding effect on commonly used namely ruler is current work investigate dynamic behaviors molten steel–slag interface fluctuation inside slab mold. Furthermore, obtain desirable operational parameters including magnetic flux density, submerged entry nozzle (SEN) depth, pole location are numerically investigated. The results demonstrate that exerted by device favorable suppressing impact upward stream with density exceeding 0.3 T. influence SEN depth mold, show steady jet pattern can be obtained through adjustment between depth. instance, when installation position 225 mm corresponds 150 mm, deflection suppressed stable profile formed. With adjustment, possibility entrapment decreased.
