The electric power control of the arc furnace is performed by a voltage control through changing the voltage tap on the furnace transformer and a current control through electrode position adjustment. In the arc furnace, current fluctuations are very sharp, because arc is struck against various shapes of material.To raise or lower the electrode according to the rapid current fluctuations requires quick response and accurate and swift forward/reverse rotation switching ability.Several electrode control systems were developed and designed to meet these requirements.This paper will show the outline of each system.
