2. graphite electrode manufacturing process The graphite electrode is mainly made of petroleum coke, needle coke as aggregate, coal asphalt as binder. It is includes calcination, forming, baking, impregnation, graphitization and machining. It is to discharge electric energy in the form of electric arc in the electric arc furnace.
Electrode consumption varies between 1.8 and 9.9 kg/t of liquid steel (Parkash, 2010) depending on the process characteristics and electrode quality. Ameling et al. (2011) reported that the electrode consumption in Germany in 2010 was approximately 1.1 kg per ton as a result of the reduction of time between the taps to 40 min and consequently the lower electricity consumption (345 kWh/t).
Graphite electrode must be connected contacted closely and straightly. Use moment spanner for connecting electrode with suitable force. The gap between electrodes shall less than 0.4mm. The holding device must hold the electrode tightly, good contact and no arc. Otherwise, the connecting area will get red and oxidized and thin, leading breakage.
Also, since graphite is a ceramic, it is sensitive to mechanical shock, and consequently must be handled and machined with care. For Graphite Electrodes the diameters start at 3/8″ (9.5 mm) For Graphite Electrodes the minimum power supply requirements are 15 KVA or higher.
