Graphite electrode is a kind of high temperature resistant graphite conductive material. Do you know the purpose and function of graphite electrode? (UHP).
(1) Used in electric arc steelmaking furnace
Graphite electrode materials can be mainly used in electric furnace steelmaking. Electric furnace steelmaking is to use research graphite electrodes to introduce working current into the furnace. The strong current can generate arc discharge through the gas environment at the lower end of the electrode, and use the heat generated by the arc for tempering. The size of the capacitance, equipped with graphite electrodes with different diameters, can be used continuously for the electrodes, against the connection between the electrodes on the electrode joints. Graphite used in steelmaking as an electrode material accounts for about 70-80% of the total graphite electrode consumption in my country.
(2) Used in submerged heat electric furnace
It is mainly used in the production of iron furnace ferroalloy, pure silicon, yellow phosphorus, calcium carbide and matte. It is characterized in that the lower part of the conductive electrode is buried in the furnace charge, so in addition to the heat generated by the arc between the electric plate and the furnace charge, the current passes through Heat is also generated by the resistance of the charge when the charge is charged.
(3) For resistance furnace
In the production process, the graphitization furnace for graphite material products, the melting furnace for melting technical glass and the production of electric furnace for silicon carbide are all resistance furnaces. The material management in the furnace is not only a heating resistor, but also a heated object.
(4) A lot of graphite electrodes are also used to be processed into various crucibles, graphite boats, hot pressing 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 graphite electrodes, graphite molds and graphite crucibles, at high temperatures, among the three graphite materials, graphite is prone to oxidation and combustion reactions, so that the plastic materials on the surface The carbon layer, the porosity structure of progressive life is loose.
