According to Maxwell electromagnetic field theory,the electromagnetic field during the mold electromagnetic stirring for 240 mm×280 mm bloom casting was simulated by means of ANSYS software.The effects of the current intensity,frequency,and mold copper on magnetic field distribution in the electromagnetic stirrer were analyzed and the relationship between the characteristics of the magnetic field and parameters of electromagnetic stirring was obtained.Resultsshow that the rotary magnetic field can generate rotary electromagnetic force in mold to make molten steel whirling at horizontal section.The magnetic induction density increases linearly with the current intensity increase,the effect of frequency on electromagnetic stirring intensity is slight when the frequency is low,while the thickness of the mold copper has a great impact on the electromagnetic stirring intensity.The simulation results are consistent with the measured ones.
