1. Use of mould nozzles, especially nozzles for feeding a continuous casting mould, constituted by a duct provided with at least one electromagnetic inductor (11) creating a rotating movement in the metal (M), characterized in that the metal level in the mould is measured, in that one acts upon a system (120), that controls the metal flow into the mould (1) through said nozzle (12) in dependence of the metal level in the mould, in that the relative variation of said flow and said level is compared with data obtained experimentally and in that the power supplied to the electromagnetic inductor(s) is varied according to said comparision. |
