To enhance the metallurgical results of mold electromagnetic stirring (M-EMS) in continuous casting of bloom, experiments for optimizing the structure of M-EMS are carried out. The operation shows that the magnetic induction intensity and bloom internal quality are obviously improved by increasing external diameter and height of mold electromagnetic stirrer, while reducing the internal diameter of the stirrer and raising the coil turns. The magnetic induction intensity is increased from 29.5 mT to 57.2 mT and the ratio of center looseness ≤ 1.0 grade is increased from 90.72% to 96.85%, free center line cracks is increased from 61.56% to 72.65%, and central segregation index of carbon is decreased from 1.10~1.16 to 1.05~1.08.
