Graphite electrodes transfer the electrical energy from the power supply to the steel melt in the electric arc furnace bath. They are made using premium petroleum needle coke, coal tar pitch, and a coating of carbon atoms. Specification for the manufacture of large-diameter graphite. Graphite is one of the occurring forms of carbon. Graphite electrodes can provide high levels of electrical conductivity and the capability of sustaining extremely high levels of generated heat. Graphite electrodes are used in heat treatment and electrochemicals. So the most common use of graphite is in making the lead pencil move voluntarily, making it an excellent conductor of electricity and good as an electrode material.
