Premium Quality Graphite Electrodes for Efficient Industrial
Melting Processes
Description For 75mm–750mm High-Performance Graphite Electrodes:
Graphite electrodes conduct electricity to generate intense heat
(up to 3,500°C) in electric arc furnaces (EAFs), melting scrap
metal or raw materials. Choosing between RP, HP, and UHP grades
depends on your furnace size, current intensity, and operational
demands. Our electrodes are precision-engineered with 99.9% pure
needle coke for unmatched performance.
RP vs. HP vs. UHP: Key Differences
Regular Power (RP): Ideal for small to medium furnaces with ≤15 A/cm² current. Cost-effective for low-intensity operations like ferroalloy production.
High Power (HP): Handles 15–25 A/cm², suited for mid-sized EAF steelmaking. Balances durability and energy efficiency.
Ultra-High Power (UHP): Built for >25 A/cm² in large-scale steel mills. Minimizes breakage and oxidation in continuous high-load cycles.
