The method of controlling velo city of grain growth in a luminum electromagnetically continuous cast-rolling by inputting rotated elect romagnetic field was introduced. The relationship between viscous fluid and frequency response was described. The ef fect of electromagnetic field frequency and melt fluctuation on grain refinement was analyzed. The best frequency band 11～15 　Hz under norm al condition (d650 mm×1 600 mm roller) was obtained.
