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.

A jacketted mold for the continuous casting of molten metal is surrounded by an enclosed cooling space holding an electromagnetic inductor for moving the molten metal in the open-ended mold. A cooling liquid is supplied to the cooling space through an inlet chamber and is removed therefrom through an outlet chamber after it has passed through a primary circuit along the tubular mold element. The outlet chamber is divided into two liquid flow circuits, one circulating the liquid from the primary circuit across the inductor at a reduced flow velocity, and the second one being arranged in parallel with the first one for directly, removing the liquid from the primary circuit to the discharge conduit immediately after it has circulated along the tubular mold element.
