The invention discloses a method for improving the internal quality of a plate blank through electromagnetic stirring. An electromagnetic stirring roller is mounted in the position, where the un-solidified rate of the casting blank is 25%-40%, of a secondary cooling area, aiming at the carbon content and the casting blank thicknesses of the different steel grades, the suitable secondary cooling specific water flow and electromagnetic stirring parameters are adopted to improve the application effect of the electromagnetic stirring technology, and reference is provided for reasonable selection of the plate blank secondary cooling area for the mounting position, the use condition and stirring parameter setting of an electromagnetic stirring device. 本申请公开了种采用电磁搅拌改善板坯内部质量的方法，所述电磁搅拌辊安装于二冷区铸坯未凝固率为25％～40％的位置，针对不同钢种的碳含量与铸坯厚度，采用合适的二冷比水量与电磁搅拌参数，以提高电磁搅拌技术的运用效果，为板坯二冷区合理选择电磁搅拌装置的安装位置、使用条件与搅拌参数设置提供参考。
