<p>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 rotates about the vertical axis of the mould and penetrates down into the mould. The magnetic field may be produced by a series of electrical conductors which are positioned about the vertical axis of the mould, each of these conductors being connected to a different phase of a multi-phase alternating current supply.</p> |
