ABSTRACT:
An apparatus for stirring a molten metal in an open topped mould, in for example a continuous casting process, includes a series of electrical conductors which are positioned above the top of the mould and about the vertical axis thereof. Each of these conductors are connected to a different phase of a multi-phase alternating current supply, so that the currents flowing in the conductors will create a magnetic field which rotates about the vertical axis of the mould and penetrates down into the mould. Ferromagnetic pole pieces are 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.
