Abstract
A method for stirring the unsolidified metal in the cast strand in continuous casting uses an asymmetrical multiphase stirring current with asymmetry caused by the phase angle of one phase of the current deviating from the phase angle of another phase of the current. In addition to the asymmetrical stirring, symmetrical stirring can be used at a location adjacent to the asymmetrical stirring so that the benefits of both types of stirring are obtained.
