摘要：
Three-dimensional mathematical models were developed for studying the molten steel flow and the trajectories of inclusions and bubbles in continuous casting mold with electromagnetic brake.The results show that the effect of the electromagnetic brake on the molten steel flow and the movement of inclusions and bubbles depends on the position of electromagnetic brake.While EMBR Ruler is installed at the exit of the submerged entry nozzle,the velocity of the main jet of molten steel from the nozzle can be decreased effectively,the velocity of the molten steel streams near the free surface and the narrow face is reduced obviously;Meantime more inclusions and bubbles could float up to the slag layer.
