Abstract (en)

[origin: WO9618469A1] A method and a device for controlling the flow in non-solidified portions (13) of a cast strand during casting of metal in a mould which is open in both ends in the casting direction by means of a two-phase or polyphase mold stirrer comprising two or more sub-stirrers, each one at least comprising a magnetic core (14a, 14b, 14c, 14d) and an ac-fed phase winding (15a, 15b, 15c, 15d) arranged around the core, such as a foil-wound coil. The cores and the foil-wound coils included in the sub-stirrers are designed and arranged in such a way that a magnetic field is generated inside the mould, which on a level with the cores, essentially comprises a magnetic field-strength component, By, oriented across the casting direction, and on a level with the phase windings, essentially comprises a magnetic field-strength component, Bz, oriented parallel to the casting direction. The flow of the melt at and adjacent the meniscus is controlled by adjusting the position of the cores relative to the meniscus such that the action of a force which arises in the melt at and adjacent the meniscus is changed by cooperation between the currents I induced in the melt and the field-strength components, By and Bz, respectively.
