Graphite electrodes are made of mixed needle coke and coal pitch , to be extruded , baked, impregnated, graphitized and machined for use as conductive material on EAF ( Electric Arc Furnace) and LF ( Ladle Furnace) for steelmaking. In steelmaking process,the EAF method recycles used iron scrap by melting at a temperature of
GRAPHITE ELECTRODES - Manufacturing Process (steel ...
8 IMPREGNATION The baked electrodes are impregnated with a special pitch (liquid pitch at 200°C) to give them the higher density, mechanical strength and electrical conductivity they will need to withstand the severe operating conditions inside the furnaces.
Graptek Graphite Electrode Catalog
Graphite electrodes are used in both DC and AC electric arc furnaces. Steelmaking workshops have to cover the cost of these consumable electrodes during new steel production process. So optimizing the usage of graphite electrodes is a cost-saving tactic. Performance parameters determine quality. Graphite electrodes are made in various grades based on electric current capability. Graphite electrodes play an important role in steelmaking.

High quality graphite electrode uhp 600mm price for arc furnaces
Graphite electrodes are used mainly in ladle furnaces, electric-arc furnace steelmaking, Yellow phosphorus furnace , Industrial silicon furnace or melting copper. They are presently the only products available that have the high levels of electrical conductivity and the capability of sustaining the extremely high levels of heat generated in
Reasons for the consumption of graphite electrode in electric ...
Side oxidation; The side loss of the electrode is due to the action of oxygen and graphite in the furnace gas to generate carbon monoxide or carbon dioxide which consumes 50 to 70% of the total electrode consumption,the side oxidation rate has a nonlinear relationship with the surface temperature of the electrode.According to the oxidation rate,it is divided into low temperature oxidation and ...
