Graphite's role as an electrode material in Electric Arc Furnaces (EAFs) is unparalleled, driven by its unique physical and chemical properties that address the extreme demands of arc-based steelmaking.
Why Graphite?
High Melting Point: Graphite sublimes at ~3,600°C, far exceeding EAF operating temperatures (1,500–3,000°C), ensuring structural integrity.
Low Resistivity: With resistivity as low as 15 μΩ·m, graphite minimizes energy loss during current transmission, reducing operational costs.
Thermal Shock Resistance: Graphite's low thermal expansion (2–4 × 10⁻⁶/°C) allows it to withstand rapid temperature fluctuations (e.g., arc initiation/cessation) without cracking.
Oxidation Resistance: At 1,500–3,000°C, graphite oxidizes slowly compared to metals or ceramics, extending electrode life.
