Classification of Graphite Electrodes

(1)General power graphite electrode Graphite electrodes with current density less than 17A/cm 2 are allowed to be used in ordinary power electric furnaces such as steelmaking, silicon and yellow phosphorus. (2)Antioxidant Coated Graphite Electrode Graphite electrodes are coated with an antioxidant protective layer (graphite electrode antioxidant). The formation of a protective layer which can conduct…
