The control of the configuration of movement of liquid metal cast in a continuous casting mould uses an immersed nozzle provided with lateral outlet holes turned towards the smaller faces of the mould. The configuration may be naturally in single loop, double loop or unstable mode. Some sliding magnetic fields act on the flow of liquid metal arriving in the mould (18) via the holes of the immersed nozzle (3). The magnetic fields are produced by linear electromagnetic induction coils (14, 14', 15, 15') arranged opposite at least one face of the mould and the nozzle in a manner to induce, or stabilize a permanent configuration in double loop mode. An Independent claim is also included for the equipment putting this method of controlling the configuration of liquid metal movement into service. |
