Abstract (en)

[origin: WO2017089396A1] The present disclosure relates to methods and a system (1) for converting iron to steel in a metallurgical container (3). A plurality of AC transmitting and receiving coils (11; 11T, 11R) is arranged in the walls (5) of the container (3) in different positions and orientations with respect to the container axis (A). A filling level (L1, L2) of an electrically conductive material and/or a dielectric material in the container (3) is determined on the basis of AC signal reception data.
