Abstract：In order to study the influence of roller electromagnetic stirring on the metallurgical effect of slabs, the effect of electromagnetic stirring on the metallurgical effect of slabs under the optimized process conditions was revealed by the field test method changing the parameters of EMS and continuous casting.The results show that the metallurgical effect of the slab improved with the electromagnetic stirring force increasing gradually under the frequency at 7 Hz and the current at 0, 100 and 400 A. With the increase of the number of roller electromagnetic stirring, the low quality of slab can be improved. When a set of electromagnetic stirring parameters are used for the same steel, good metallurgical effect can be obtained under the condition of comprehensive optimization of continuous casting process parameters. The best metallurgical effect of the slab can be achieved with the frequency of electromagnetic stirring at 7 Hz, the casting speed at 0.9 m/min and the current at 400 A.
