[0002] Graphite electrodes are a type of electrode used in electric arc furnaces for steel production. Made from high-purity graphite, they are an essential component of the steelmaking process, and graphite electrodes have high thermal conductivity, high melting point, low electrical resistance, and high resistance to oxidation and corrosion. These properties make them ideal for use in EAF steelmaking processes that are subject to extreme temperatures and harsh conditions.
