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.
