(1) Ordinary power graphite electrode: Allow the use of current density of less than 17a/cm 2 graphite electrode, mainly used in steelmaking, smelting silicon, refining of yellow phosphorus, such as ordinary power electric furnace.
(2) Anti-oxidation coating graphite electrode: The surface coating a layer of antioxidant protective layer of graphite electrode, forming both conductive and high-temperature oxidation protective layer, reduce the electrode consumption when steelmaking.
(3) High power graphite electrodes: Graphite electrodes, which allow the use of current density of 18~25a/cm 2, are mainly used in high power arc furnaces for steelmaking.
(4) Ultra-high power graphite electrode: Allow the use of the current density of more than 25a/cm 2 graphite electrode. Mainly used in ultra-high power steelmaking arc furnace.
