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.

Most copper mined today is used to conduct electricity - mostly as wiring. It is also an excellent conductor of heat and is used in cooking utensils, heat sinks, and heat exchangers. Large amounts are also used to make alloys such as brass (copper and zinc) and bronze (copper, tin, and zinc).
Chemical Composition: Copper, Cu
Streak: Metallic copper red
Color: Copper red on a fresh surface, dull brown ..
ead (Pb), a soft, silvery white or grayish metal in Group 14 (IVa) of the periodic table. Lead is very malleable, ductile, and dense and is a poor conductor of electricity. Known in antiquity and believed by the alchemists to be the oldest of metals, lead is highly durable and resistant to corrosion.
By the early 2000s, 88 percent of apparent U.S. lead consumption was in lead-acid batteries, which was a substantial increase from 1960 when only 30 percent of global lead consumption was in lead-acid batteries. Today, the other significant uses of lead are in ammunition, oxides in glass and ceramics, casting metals, and sheet lead.
Ferro Manganese is an alloy with high percentage of manganese, which is made by heating a mixture of oxides, MnO2 and Fe2O3 with high carbon content in blast furnace or an electric arc furnace-type system. The oxides go through carbothermal reduction in the furnaces that result in producing Ferro Manganese. Ferro Manganese is used as deoxidizer and desulfurizer for production of steel .
