One of the main causes of the nonuniform melting of a charge in the EAF bath is found to be the asymmetry of the short circuit and interphase power transfer. The electric power deficiency at the “dead” phase of a furnace is shown to be 1.2 MWh. We propose to equalize the energy disbalance using flexible control of the operating conditions of gas–oxygen burners. For this purpose, an algorithm is developed to estimate the changes in the geometric zone sizes in the EAF bath using the technique of determining angular arc radiation coefficients. The intensity of charge melting due to arc radiation is shown to decrease sharply with increasing well diameter, and the main component of the furnace capacity is the melting of a solid charge in a molten metal bath.
