What are the typical applications of RP, HP, and UHP grade furnace graphite electrodes?

The grade of furnace graphite electrodes is selected based on EAF power and production goals:

RP Grade: Used in small, outdated EAFs (≤50 tons) with limited power (<50 MW). Common in regional or specialty steel mills where cost prioritizes over efficiency.

HP Grade: Applied in mid-sized EAFs (50-100 tons) with 50-80 MW power. Ideal for mills producing construction steel or semi-finished products, balancing efficiency gains with upfront costs.

UHP Grade: Exclusive to large EAFs (≥100 tons) in advanced steel plants. These electrodes support 80-120 MW power inputs, critical for producing high-quality steel (e.g., automotive, appliance) with tight quality and productivity requirements. UHP electrodes also align with global decarbonization trends by reducing energy waste.
