Specifications

RP HP UHP Carbon Graphite Electrode
Grade:RP,HP,SHP, UHP
Diameter:50-600mm (2-24 inch)
Length:according to customer's request

Graphite electrodes are widely used in Industrial arc furnace, Steel mills, Foundries, or other metallic and nonmetallic materials, etc.

*We supply RP, HP, and UHP and impregnated(IP) graphite electrodes (Dia.50-600mm) with low electrical resistivity and ash worked in electric-arc furnace steelmaking, industrial silicon furnace and corundum furnace, and so on.
