Compared with copper, graphite has advantages such as less consumption, faster discharge rate, lighter weight and smaller thermal expansion coefficient, so it gradually replaces copper electrode to become the mainstream of discharge processing materials. According to the capacity of the electric furnace, graphite electrodes of different diameters are used. For continuous use of the electrodes, the electrodes are connected by the threaded joint of the electrodes. The graphite electrodes used in steel making account for about 70-80% of the total consumption of the graphite electrodes. 

Graphite electrode consumption and breakage is common in practice. What causes these? Here is the analysis for reference.


Body Breakage

Nipple Breakage



Electtode Loss


Electorde   Consumption

Non-conductors   in charge






Heavy scrap in   charge






Transformer   overcapacity


Three phase   imbalance



Phase Rotation






Excessive   Vibration





  Clamper Pressure 






Roof electrode socket not align with electrode






Cooling water sprayed on electrodes above roof







Scrap   preheating







Secondary   voltage too high



Secondary   current too high


Power too   low 



Oil   consumption too high





Oxygen   Consumption too high





long time   heating







Electrode   dipping






Dirty   connection part






Poor maintenance for lift plugs and tightening tools






Insufficient   connection
