FIELD: metallurgy. ^ SUBSTANCE: invention relates to electrothermics field, particularly it concerns to regulation of process variables at manufacturing of fused phosphates, calcium carbide in ore-thermal furnaces and can be used in non-ferrous metallurgy. Regulation method of melt level in bath of ore-thermal furnace includes regulation of phase voltage and electrode current. Additionally it is measured value of constant component of phase voltage, and level of melt at specified value of current is defined according to formula: H=K*Ucc, where H - melt level, mm; Ucc - value of constant component of phase voltage, mV, K - coefficient, depending on value of phase voltage, mm/mV. ^ EFFECT: achievement of high accuracy of measurement. ^ 1 dwg, 1 tbl, 1 ex
