FIELD: metallurgy. SUBSTANCE: invention relates to the metallurgy industry. Magnesium level and the skull characteristics in the titanium reduction reactor determining method, based on the EMF measurements in the receiving coil, induced by the electromagnetic field from located around the retort the exciting windings set, contains the steps, on which for the determination currents of different frequencies are used, at that, first, by the electrodynamics equations numerical solving, developing the reference base of the EMF calculated values in the located above the reactor receiving coil, with the molten magnesium different specified levels, different titanium skull given positions and sizes for the supply current given set of frequencies in the range of 1–50 Hz, and then, in the process of titanium reduction, with the same set of current parameters in the excitation coils, measuring the EMF values in the receiving coil, which are compared with the reference ones, and the least standard deviation is determined by the smallest standard deviation method, and the molten magnesium level, the titanium skull position and size are judged by it. EFFECT: increase in the molten metal level determining accuracy and the expansion in the method possibilities. 5 cl, 13 dwg
