Abstract:A three-dimensional model of the electromagnetic field of electromagnetic brake (EMBR) in the mold is presented. The computational model is applied to investigate the effects of magnetic induction intensity in slab mold under constant current conditions. The calculated results of magnetic induction intensity are compared with measured data in a steel plant. The magnetic induction intensity of different cross sections of mould is discussed with the different currents. The magnetic induction intensity in the iron core zone is larger than other parts, the magnetic induction intensity along the height direction of mold is characterized by sinusoidal distribution. Under braking current 300-700 A, the magnetic induction intensity is close to 0 in which the distance to the mold top about 400-450 mm. The magnetic induction intensity direction is opposite in the upper and lower mold. The magnetic induction intensity distribution is similar with various currents, but its value is changeable. The magnetic field in the mold is mainly concentrated in the horizontal direction, and the values of other direction component are smaller.
