Based on the finite element method

temperature field in casting process the 1st round billet casting machine from the Baotou Steel company were analyzed to find a proper location for positioning the final electromagnetic stirring（F-EMS）stirrer.Through applying transient magnetic field analysis method

the distribution of magnetic flux density and electromagnetic force in the bloom during stirring process was analyzed

and process parameters of F-EMS were optimized.With a casting speed velocity of 0.45m/min

specific water flow of 0.18L/kg and superheat value degree of 25℃

the optimized electric stirring parameters for round bloom with 430 mm in diameters were presented as follows:current of 250 A

frequency of 10 Hz.Magnetic flux density in the stirrer under no-load was measured.The results were well in agreement with simulated ones.
