Application:1. Electric arc steelmaking furnace.Graphite electrode is mainly used in electric furnace steelmaking. Electric furnace steelmaking uses graphite electrodes tointroduce current into the furnace. A strong current generates an arc discharge through the gas at the lower end of the electrode,and uses the heat generated by the arc to smelt.2. Ore-heating furnaces.Graphite electrode ore-heating furnaces are mainly used to produce ferroalloys, pure silicon, yellow phosphorus, matte and calciumcarbide, etc., which is characterized by electrical conductivity...3. Resistance furnaces.Graphitization furnaces for producing graphite products, melting furnaces for melting glass, and electric furnaces for producingsilicon carbide are all resistance furnaces.4. Used for processing.A large number of graphite electrode blanks; also used for processing into various crucibles, graphite boats, hot die castingmolds and heating elements for vacuum electric furnaces, etc...Packing
