ultra-high power graphite electrode

   PRODUCT DESCRIPTION

Ultra-High Power (UHP) graphite electrode is mainly used for ultra high power electric arc furnaces with the current density greater than 25 A/cm2. UHP graphite electrode is used for the recycling of steel in the electric arc furnace industry. Its main ingredient is high-value needle coke which is made from either petroleum or coal tar. Graphite electrodes are finished with a cylinder shape and machined with threaded areas at each end. In this way, the graphite electrodes can be assembled into an electrode column using electrode nipple.

Features：

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.
