Graphite electrode raw materials use the domestic petroleum
coke and pitch coke and imported Japanese needle coke .HP grade
graphite electrode contain *0% imported needle coke. UHP graphite
electrode contain more than *0% imported needle coke. They are
widely used in electric arc furnace(EAF), ladle furnace(LF) for the
production of alloy steel, metal and nonmetallic materials. They
are characterized by low resistance, good electric and thermal
conductivity, high resistance to oxidation and thermal shock, high
mechanical strength, etc
