The solidified structures of horizontally continuous casting (HCC) of super-thin slab and its relations with the current were studied under the electromagnetic vibration (EMV). The results show that, under the action of the periodical forces from EMV, the solidified structures of the super-thin slab of pure tin is greatly refined, and the extent of grain refinement is increased with the magnitude of alternating current. For the Sn-10%Pb alloy, it is shown that the EMV promotes the growth of equiaxed grains in the center of super-thin slab, and the grains are refined with the alternating current increasing. This is useful to prevent some solidification defects in the horizontally continuous casting of super-thin slab, such as columnar grains butting, porosity, inclusions and gases gathering, and composition segregation in the centre of slab.
