UHP 400mm*1800mm UHP 450mm*1800mm Used in steel, cement and glass manufacturing, expanded graphite - based sealing gaskets, graphite grease, braid, brushes, brake lining, etc.
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.

Technical parameters of ultra-high power graphite electrode in 400arc furnace Specification for the Use of Ultra-High Power Graphite Electrodes in 400 Electric Arc Furnace Points to note for the use of graphite electrodes: 1, wet graphite electrode, dry before use. 2, remove the foam protective cap on the spare graphite electrode hole, check whether the inner thread of the electrode hole is complete. 3, clean up spare graphite electrode surface and hole thread with compressed air without oil and water; Avoid cleaning sand cloth with steel or metal brushes. 4, carefully rotating the connector into the electrode hole at one end of the backup graphite electrode(it is not recommended to load the connector directly into the electrode removed from the furnace), not to collide threads. 5, the electrode hanging equipment(recommended graphite hanging equipment) into the electrode hole at the other end of the backup electrode. 6, when lifting the electrode, loosen the soft material to the bottom of the end of the standby electrode connector to prevent the ground from hitting the connector; Lift the pendant ring with a hook, and the lifting electrode must be stable to prevent the electrode from loosening from the B end or colliding with other fixing devices. 7, hanging the spare electrode to the top of the electrode to be connected, pointing at the electrode hole and slowly falling; Rotate the backup electrode so that the spiral hook rotates with the electrode to drop; When the two electric extremes are 10-20mm apart, the exposed parts of the two ends and joints of the electrode are cleaned again with compressed air; When the electrode is finally completely decentralized, it must not be too violent. Otherwise, due to violent collisions, the electrode holes and joints will be damaged.
