The purpose and performance of 700 graphite electrode

700 graphite electrode is a kind of high temperature resistant graphite conductive material. Do you know the purpose and performance of 700 graphite electrode?

700 graphite electrode classification: ordinary power 700 graphite electrode (RP); high power 700 graphite electrode (HP); quasi-ultra-high power 700 graphite electrode (SHP); ultra-high power 700 graphite electrode (UHP).

(1) Used in electric arc steelmaking furnace

The 700 graphite electrode material can be mainly used for electric furnace steelmaking. Electric furnace steelmaking uses the research 700 graphite electrode 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 700 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 700 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 700 graphite electrode blanks are also used to process various crucibles, graphite boats, hot die casting molds and vacuum electric furnace heating elements and other special-shaped products.

It should also be noted that among the graphite materials in the three high-temperature composite materials including 700 graphite electrode, graphite mold and graphite crucible, the three graphite materials at high temperature, graphite is easy to oxidize and burn reaction, so that the carbon on the surface of the plastic material Layer, improve the porosity of life structure is loose.
