Abstract: The influence of continuous casting electromagnetic stirring process on the magnetic properties, secondary recrystallization, and primary recrystallization of 0.30 mm thick high magnetic induction oriented silicon steel were studied in this paper. The results showed that the final product samples using electromagnetic stirring process have a lower iron loss of P1.7/50 by 0.04 W/kg and a higher induction of B800 by 0.03 T compared to those without electromagnetic stirring. With electromagnetic stirring process, the high magnetic induction oriented silicon steel has a better magnetic property. The main reason is that for samples under electromagnetic stirring process the grain size of the primary recrystallization is smaller, the temperature of the secondary recrystallization is lower, the proportion of small angle Goss texture of the primary recrystallization is higher, and the deviation angle of the <100> texture around the ND direction is smaller after secondary recrystallization.
