Graphite electrode series include RP Graphite Electrode, HP Graphite Electrode, UHP Graphite Electrode etc .

Graphite electrode series include RP Graphite Electrode, HP Graphite Electrode, UHP Graphite Electrode etc .

   

Graphite Electrode is mainly used for steel-making in electric furnace, mineral hot furnace and electric resistance furnace. Graphite electrode conducts electric current into the furnace. Electric current produces arc in the smelting district in the electric furnace, when the temperature increase to about 2000,smelting begins. Our series of graphite electrode is applicable to the common furnace and high power furnace with high pressure and short arc.
