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.
