Abstract
A method of continuously casting metals, inter alia steel or metals having similar characteristics, wherein liquid metal is poured into a mould having a circular cross-section and a substantially vertical axis, the mould wall is continuously cooled, the liquid steel is rotated in the mould by electromagnetic field windings placed in or level with the mould, and the solidified bar is continuously withdrawn at the bottom of the mould, in which the mould is supplied by a liquid steel stream which is inclined and eccentric with respect to the mould axis, so that when it strikes the surface of the liquid metal in the mould, it has a component substantially tangential to the geometrical circle extending through the point of impact and centered on the mould axis, thus producing a meniscus, the vertical distance between the base of the meniscus and the top end of the field windings being maintained at a sufficient value not to produce a substantial electromagnetic field at the meniscus, inter alia at its top part.
