Graphite electrodes are mainly used in the steelmaking process. Iron scrap gets melted in an electric arc furnace and recycled. As a kind of conductor, they are an essential component in this kind of furnace. It can be divided into ordinary power grade, high power grade and ultra high power grade according to their quality indicators
HP graphite electrode is mainly made of petroleum coke and needle coke, It is allowed to carry the current density 18-25A/cm2.Generally it is designed for high power electric arc furnace steel-making.
HP grade graphite electrode add 30% imported needle coke. UHP graphite electrode use more than 80% imported needle coke. They are widely used in electric arc furnace, ladle furnace for the production of alloy steel,metal and nonmetallic materials. They are characterized by low resistivity, good electric and thermal conductivity, high resistance to oxidation and thermal shock, high mechanical strength, etc
