ABSTRACT:
An apparatus for stirring a molten metal in an open topped mould, in for example a continuous casting process, includes means positioned above the mould for producing a magnetic field which moves linearly and penetrates down into the mould. The magnetic field may be produced by a series of electrical conductors positioned above the mould and arranged parallel to one another, each of these conductors being connected to a different phase of a multiphase alternating current supply. Ferromagnetic pole pieces may be associated with the conductors to provide a low reluctance flux path, which will reduce leakage of the magnetic field above the conductors and concentrate the field below the conductors where it penetrates down into the mould.
