Grafite carbon UHP with nipples for arc furnace graphite electrode
Graphite electrodes are mainly used for electric furnace steelmaking. Electric furnace steelmaking uses graphite electrodes to introduce current into the furnace. The strong current generates arc discharge through the gas at the lower end of the electrode, and the heat generated by the arc is used for smelting. According to the capacity of the electric furnace, graphite electrodes of different diameters are used. In order to make the electrodes continuous, the electrodes are connected by electrode threaded joints. Graphite electrodes for steelmaking account for about 70-80% of the total graphite electrode usage. 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 resistance of the charge also generates heat when the current passes through the charge. The graphitization furnace used to produce graphite products, the melting furnace for melting glass, and the electric furnace used to produce silicon carbide are all resistance furnaces. The materials loaded in the furnace are both heating resistors and objects to be heated.
