An algorithm is developed to estimate the rate of charge melting in the electric arc furnace laboratory and its geometric sizes. An electric-arc instability index is proposed as a parameter for on-line control of the heat state of the bath and the rate of metal scrap melting. In practice, a decision about turning off a furnace in melting a charge or about the beginning of the end oxidation stage of a heat is delayed, which leads to an increase in the time of furnace operation under an electric current and in the specific electric power consumption.
