Products Grades : NP/RP, HP, UHP
Normal Power Graphite Electrodes (NP)
High Power Graphite Electrodes (HP)
Ultra High Power Graphite Electrodes (UHP)
All graphite electrodes are offered with tapered nipples, i.e. 3 or 4 threads per inch, and meet the internationally accepted tolerances as per NEMA CG 1/ IEC 60239 / JIS R7201 standards.
Application Of Graphite electrodes: Graphite electrodes are used mainly in ladle furnaces,electric-arc furnace steelmaking,Yellow phosphorus furnace , Industrial silicon furnace or melting copper. They are presently the only products available that have the high levels of electrical conductivity and the capability of sustaining the extremely high levels of heat generated in this demanding environment.High Quality Needle Coke in HP&UHP graphite electrode,ensure the electrode application is perfect. Graphite electrodes are also used to refine steel in ladle furnaces and in other smelting processes.
Characteristics Of Graphite electrodes:
Anti-oxidation treatment for longevity.
High-purity,high-density,strong chemical stability.
High machining accuracy,good surface finishing.
High mechanical strength,low electrical resistance.
Resistant to cracking & spalling.
High resistance to oxidation and thermal shock.
