Final EMS parameters in the continuous bloom casting have been optimized by experimental and simulated researches. Simulation results show that the temperature gradient in the molten melt can be decreased and simultaneous solidification can be obtained with the final EMS. When the current is 600 A and frequency is 6 Hz, the maximum temperature gap between the inside and the brim of the melt bottom is 1.79 °C, which is 49.3% of that without EMS. Processing parameters are rectified based on the research results, the number of the shrinkage cavities is limited and the maximum diameter of the cavity is decreased.
