HP Graphite Electrode for Steel Smelting
Electric furnace steelmaking mill is the largest user of graphite electrodes. Graphite electrodes used in steelmaking accounts for 70%-80% of the total graphite electrodes production. Graphite electrodes are used to conduct electric current into electric furnace, electric arcs generated between electrodes end and loaded materials can release large amount of heat for high temperature smelting.
