Abstract

Electrode controllers have a significant influence on the productivity of electric arc furnaces. Melting time, electrode, refractory, energy consumption, stress on resources (e.g. electrode arms, high current lines, etc.) are all influenced by electrode control. Constant power input at defined working points, short tap-to-tap times and less electrode and refractory material consumption are the most important requirements from a furnace operations perspective. The ISEC electrode controller was developed based on such modern furnace operation requirements for electric arc and ladle furnaces in the iron and steel making industry (EAF, LF, VHD/VAD).
