Electrodes arm for the electric arc furnace
In the electric arc furnace process, the cold metallic charge, mainly scrap, is melted by the energy of electric arcs generated between the tips of graphite electrodes and the conductive metallic charge. The three electrodes and the furnace roof are raised and swung away from the furnace shell to allow the charging of scrap. The electrodes maintain the arc in accordance with the voltage and current level selected to produce the desired power input at the desired arc length for melting and refining. As the noise generated by the arcs is high during the melt-in-period, with levels up to 120 dBA, special protection is provided to the operators cabin and the furnace has a special enclosure.
