Product Specification
Graphite Electrodes
UHP (Ultra High Power) grade graphite electrodes for Ladle Furnace (LF) steelmaking operations. Manufactured to strict dimensional and physical tolerances, supplied with preset nipples and protective end caps on strong wooden crates. Available in Ø450mm and Ø500mm nominal diameters.
Applications
- Ladle Furnace (LF) secondary metallurgy in steelmaking
- Electric Arc Furnace (EAF) primary steelmaking
- Refining and alloying in meltshop operations
- High-power steel production requiring UHP grade electrodes
