 UHP Graphite electrodes
Graphite electrode is one of the most important metallurgical products, mainly used as conductive material in electric arc furnace metallurgy production. UHP graphite electrodes are mainly used for steelmaking high-power and ultra-high power electric furnaces.
Electric Arc Furnace (EAF)
DC electric arc furnace
AC electric arc furnace
Submerged arc furnace
Ladle Furnace (LF)

Advantage
UHP graphite electrode is mainly used for ultra high power electric arc furnaces with the current density greater than 25 A/cm2.
● Withstand large currents, high discharge rate.
● Good dimension stability, not easy to deform.
● Resistant to cracking & spalling.
● High resistance to oxidation and thermal shock.
● High mechanical strength, low electrical resistance.
● High machining accuracy, good surface finishing.

Packaging

The graphite electrode is packed in wooden crates, and the nipples are packed in wooden cases or pre-set in the electrodes. Electrodes would be covered with polythene sheet to protect the same from dust and moisture, and fasten with steel strips, which is good looking and firm. Proper and safe seaworthy packing, easy for forklift handling. Necessary measures would be provided to avoid possible damages to nipple threads-such as protective foam and rubber caps.
