Why Graphite Electrodes Dominate High-Temperature Manufacturing

Graphite electrodes serve as critical components in electric arc furnaces (EAFs), accounting for 75% of global steel recycling operations. With a global market value projected to reach $12.8 billion by 2028 (Grand View Research), their thermal conductivity (160 W/m·K) and melting point (3,600°C) outperform alternative materials. Over 68% of lithium-ion battery anode production now utilizes synthetic graphite electrodes due to enhanced purity standards (>99.9%).

Material Science Behind Electrode Efficiency

Three key properties make graphite ideal:

1. Electrical Conductivity: 3× higher than silicon carbide
2. Thermal Shock Resistance: Survives 1,200°C/minute fluctuations
3. Mechanical Stability: Compressive strength up to 45 MPa

Recent advancements include needle coke variants reducing electrode consumption by 22% in continuous casting operations.
