Abstract
A method of continuous centrifugally casting of metal strands of non-circular, preferably substantially square cross-section, in which the metal continuously passing through an ingot mold of corresponding cross-section is rotated about the longitudinal axis of the mold by means of a rotating magnetic field which may be created by a stationary multi-phase inductor, and wherein the metal in the mold is continuously replenished by a jet of liquid metal impinging on the free surface of the metal in the mold at a point of impact in the neighborhood of one corner of the mold, preferably at a point located on the diagonal substantially midway between the mold wall and the center of the mold. This method causes any slack contained in the metal to concentrate at the center of the free upper metal surface in the mold, from where it can be easily removed.
