Graphite electrode is a kind of high temperature resistant graphite conductive material. Do you know the purpose and performance of graphite electrode?
Graphite electrode classification: ordinary power graphite electrode (RP); high power graphite electrode (HP); quasi-ultra-high power graphite electrode (SHP); ultra-high power graphite electrode (UHP).
For electric arc steelmaking furnace
Graphite electrode materials can be mainly used for electric furnace steelmaking. Electric furnace steelmaking uses research graphite electrodes to introduce working current into the furnace. The powerful current at the lower end of the electrode can affect arc discharge through these gas environments, and the heat generated by the arc is used for smelting. The size of the electric capacity is equipped with graphite electrodes with different diameters, which can be used continuously, and the connection between the electrodes against the electrode joints. Graphite used in steelmaking as an electrode material accounts for about 70-80% of the total consumption of graphite electrodes in China.
Used for submerged electric furnace
It is mainly used to produce iron furnace ferroalloy, pure silicon, yellow phosphorus, calcium carbide and matte. Its characteristic is that the lower part of the conductive electrode is buried in the charge, so in addition to the heat generated by the arc between the electric plate and the charge, the current passes through the charge At this time, heat is also generated by the resistance of the charge.
For resistance furnace
In the production process, the graphitization furnace for graphite material products, the furnace and production of melting technical glass, and the electric furnace for silicon carbide are all resistance furnaces. The management of the materials in the furnace is both a heating resistor and an object to be heated.
A large number of graphite electrode blanks are also used for processing into various crucibles, graphite boats, hot die casting molds and vacuum electric furnace heating elements and other special-shaped products.
