UHP graphite electrode big diameter

 UHP Graphite Electrode is mainly used for ultra high power electric arc furnaces with the current density greater than 25 A/cm2.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:

1. good electrical conductivity;

2.good thermal conductivity;

3.high resistance to oxidation;

4.good stable thermal shock;

5.precise machining accuracy.
