Product Description
High-Performance Graphite Electrodes for Steel Manufacturing
Premium graphite electrodes engineered to conduct electricity and generate intense heat up to 3,500°C in electric arc furnaces, efficiently melting scrap metal and raw materials for steel production.
Electrode Grade Selection Guide
Regular Power (RP): Ideal for small to medium furnaces with ≤15 A/cm² current density, cost-effective for low-intensity operations
High Power (HP): Handles 15-25 A/cm² current density, balanced durability and energy efficiency for mid-sized EAF steelmaking
Ultra-High Power (UHP): Built for >25 A/cm² in large-scale steel mills, minimizes breakage and oxidation in continuous high-load cycles
