Introduction to anti-oxidation coated graphite electrode
Graphite electrode with an anti-oxidation protective layer (graphite electrode antioxidant) on the surface. It forms a protective layer that is both conductive and resistant to high-temperature oxidation, reduces electrode consumption during steelmaking (19%~50%), extends the service life of the electrode (22%~60%), and reduces the power consumption of the electrode.
