Abstract
An electromagnetic stirring device and a method for a secondary cooling zone during slab continuous casting. The device has a main body, an opening adjustment assembly, and a secondary cooling assembly. The main body has a protection housing (), a phase sequence control assembly, an iron core () and an electromagnetic coil () for carrying out variable-direction electromagnetic stirring on a molten steel by a three-phase current phase sequence transformation. The opening adjustment assembly has an air cylinder (), a fixed base (), a movable joint shaft () and a silicon steel sheet group insert () for adjusting online opening degree of the closed annular iron core by a movable joint structure. The secondary cooling assembly has a cooling water inlet () and a cooling water nozzle () for cooling the electromagnetic coil and spraying cooling water to a surface of a cast slab ().
