Abstract：The flow characteristics of molten steel in the mold are one of the primary factors causing slab defects.Taking the 1 200 mm×135 mm slab continuous casting mold of a factory as the research object,a three-dimensional slab mold electromagnetic braking mathematical model was established,and the influence of electromagnetic braking installation position on the flow and heat transfer of molten steel in the mold was studied.The results show that when the center position of the electromagnetic brake is reduced from Z=270 mm to Z=470 mm,the velocity of the molten steel on the free surface of the mold decreases first and then increases,the impact depth of the molten steel in the mold gradually decreases,and the temperature field distribution of the central section of the mold gradually becomes symmetrical.When the electromagnetic brake position is too low,due to the unreasonable magnetic field distribution,the surface temperature distribution of the slab is not uniform,the temperature difference at the outlet of the narrow side of the mold increases,and the solidified shell is thinned.When the electromagnetic brake center position is Z=370 mm,the flow and heat transfer effect of molten steel in the slab mold is better,the maximum flow rate of the free surface center of the mold is 0.14 m/s,the solidification front of the slab is stable,and the solidification shell at the mold outlet is evenly distributed.
