Abstract
The problems of increasing the arc furnace power by increasing the current and the supply voltage are considered. The increase in the voltage under the optimum melting period conditions should be consistent with the inductance of the prereactor. An increase in the electrode diameter is shown to narrow the possibilities of using various supply voltages under the optimum metal melting conditions. The maximum EAF power at allowable currents and voltages is 300–310 MVA. The requirements imposed on the reliability of the furnace lining are found to decrease the allowable limits of increasing the voltage and the furnace power.
