Graphite electrodes are mainly made of petroleum coke and needle coke as raw materials and coal tar pitch as binder. They are made by crushing and screening ,kneading, forming,baking ,impregnation graphitization and machining. They are released in the form of electric arcs in an electric arc furnaceï¼?then heating and melting the raw materials as electrode.GE can be classified into RP, HP and UHP according to different specification. The products have the advantages of low resistivity, low ash content, uniform structure, good thermal vibration resistance, high mechanical strength, low thermal expansion coefficient, precise fit of electrode and nipple, etc, which is an excellent materials for electric steel-making and ore smelting.
ï??Application:
1. Used in electric arc steel making furnaces: Graphite electrodes are mainly used for electric furnace steel -making. Electric furnace steel-making uses graphite electrodes to introduce current into the furnace, and a strong current passes through the gas at the lower end of the electrode to generate arc discharge, which is caused by the use of electric isolation heat for smelting.
2. Used in submerged electric furnace: graphite electrode submerged heating furnace is mainly used to produce ferroalloy, pure silicon, yellow phosphorus, matte and calcium carbide.
3. For resistance furnaces: graphitization furnaces for the production of graphite products, furnaces for melting glass and electric furnaces for the production of silicon carbide are all resistance furnaces. The raw materials in the furnaces are not only heating resistors, but also heated The goal.
4. For processing: Many graphite electrode blanks are also used for production and processing into various products such as crucibles, graphite boats, hot die casting molds and vacuum furnace heaters.

The graphite electrode comprises: (1) Regular power graphite electrode( RP grade Graphite Electrode) . Graphite electrode with current density less than 17a / cm2 is allowed to be used in common power electric furnaces for steelmaking, silicon smelting and yellow phosphorus smelting. (2) Oxidation resistant coating graphite electrode. A graphite electrode coated with an anti-oxidation protective layer (graphite electrode anti oxidant). The formation of both conductive and high temperature oxidation resistant protective layer can reduce the electrode consumption (19% ~ 50%), prolong the service life of the electrode (22% ~ 60%), and reduce the electric energy consumption of the electrode. The popularization and application of this technology can bring such economic and social effects as follows: 1. The unit consumption of graphite electrode is less, and the production cost is reduced to a certain extent. For example, according to the consumption of 35 graphite electrodes per week and 165 refining heats of LF refining furnace in a steel-making plant without shutdown in the whole year, 373 (153 tons) electrodes can be saved every year by using graphite electrode oxidation resistance technology, and RMB 2585700 can be saved by RMB 16900 per ton of ultra-high power electrode per year. 2 The graphite electrode consumes less electricity, saves the unit electricity consumption of steelmaking, saves the production cost, saves energy! 3. Because the graphite electrode is replaced less times, the labor amount and risk coefficient of operators are reduced, and the production efficiency is improved. 4 Graphite electrode is a high consumption and high pollution product, which has a very important social significance in the days of promoting energy conservation, emission reduction and environmental protection. This technology is still in the stage of research and development in China, and some domestic manufacturers have begun to produce it. It is widely used in Japan and other developed countries. At present, there are also companies that import the anti-oxidation protective coating in China. (3) High power graphite electrode (HP grade Graphite Electrode). Graphite electrode with current density of 18-25a / cm2 is allowed to be used in high power electric arc furnace for steelmaking. (4) Ultra high power graphite electrode( UHP grade Graphite Electrode). Graphite electrode with current density greater than 25A / cm2 is allowed. It is mainly used in ultra high power EAF.
