650mm high power hp graphite electrodes
Usage and performance of 650mm high power hp graphite electrodes
650mm high power hp graphite electrodes is a kind of high temperature resistant graphite conductive material. Do you know the purpose and performance of 650 high power hp graphite electrodes?
650 hp graphite electrodes category: ordinary power high power hp graphite electrodes (RP); high power 650mm high power hp graphite electrodes (HP); quasi-ultra-high power 650mm high power hp graphite electrodes (SHP); ultra-high power 650mm high power hp graphite electrodes (UHP).
(1) Used in electric arc steelmaking furnace
650mm high power hp graphite electrodes material can be mainly used for electric furnace steelmaking. Electric furnace steelmaking uses research 650mm high power hp graphite electrodes to introduce working current into the furnace. The powerful current at the lower end of the electrode can affect the arc discharge through these gas environments, and the heat generated by the arc is used for smelting. The size of the capacitance is equipped with 650mm high power hp graphite electrodes with different diameters, which can be used continuously, and the connection between the electrodes against the electrode connector. Graphite for steelmaking as an electrode material accounts for about 70-80% of the total consumption of 650mm high power hp graphite electrodes in China.

(2) Used in 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. Therefore, 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 electrical resistance of the charge.
(3) Used in 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.
(4) A large number of 650mm high power hp graphite electrodes blanks are also used to process various crucibles, graphite boats, hot die casting molds and vacuum electric furnace heaters and other special-shaped products.
It should also be noted that among the graphite materials in the three high-temperature composite materials including 650mm high power hp graphite electrodes, graphite molds and graphite crucibles, the three graphite materials at high temperature, graphite is easy to oxidize and burn reaction, so that the surface of the plastic The carbon layer of the material improves the porosity of life and the structure is loose.
