Description Of HP Graphite Electrode
HP graphite electrode is the conducting element for electric arc furnaces steelmaking. It is made of petroleum coke, needle coke, coal pitch and produced by a series of strict production processes. High-current lines insert through the graphite electrode port inside the furnace body. This will releases electric energy in the arc furnace to heat the furnace.
The demand for the larger diameter electrodes has been increasing as EAF furnace sizes become larger. Graphite electrodes with diameter of 500 mm or 600 mm have become increasingly popular in recent years.
