A corrosion-resistant graphite electrode (600mm) is engineered to resist oxidation, chemical attack, and thermal erosion in extreme EAF and LF conditions.
Corrosion Resistance Mechanisms:
High-Density Structure: Minimizes pore exposure to oxygen.
Oxidation Inhibitors (e.g., Boron, Silicon Carbide): Form protective layers.
Low Porosity (<10%): Reduces air ingress.
Composition (Enhanced For Corrosion Resistance):
