Abstract：The method combined finite element analysis with experiment measurement were used to study the optimum stirring parameters, the stirring parameters modifications according to the variation of the thickness of the casting slab and the metallurgical effect. The results show that the optimum stirring parameters of the high thrust roller strand electromagnetic stirrer （S-EMS） for the slab thickness of 230 mm are current of 500 A and frequency of 7 Hz. Applied the same roller S-EMS to different slab thicknesses of the casting blank, and in order to achieve good metallurgical effects, the current and the frequency will need to increase linearly and decease gradually each, as the thickness of the casting slab increases. The metallurgical effects of using the products indicates that the application of high thrust roller S-EMS can significantly improve the solidified structure of the casting slab, and increase the equiaxed crystal ratio.
