ultra-high power graphite electrode

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.

Bulk density  :  1.7~1.8 g/cm3

Flexural strength : 10~23Mpa

   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.
