【Abstract】 The practice of continuous casting production indicated that the flow pattern of molten steel in the mold directly affects the quality of bloom/slab and final products. The molten steel flow-control technologies in the continuous casting mold for improving the quality of final products and achieving the high-efficiency continuous casting are of great helpful and significant. The multiphase transport behavior in the continuous casting mold for different types of flow-control methods including the bloom/round billet mold electromagnetic stirring(M-EMS), the slab mold electromagnetic brake(EMBR), the slab mold electromagnetic level stabilizer(EMLS) and the slab mold electromagnetic level accelerator(EMLA) have been investigated respectively. The metallurgical mechanism and the multiphase transport phenomena including magnetic field, flow field, temperature field, inclusion removal and steel/slag interface fluctuation have been analyzed, in which the metallurgical effects on the final bloom/billet and slab qualities also have been performed by a series of industrial applications.更多还原
