Description:

Allows the use of current density greater than 25A/cm2,mainly used for ultra-high power steel making electric arc furnace.

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.

Application:

UHP Graphite electrodes,semiconductor manufacturing,iron,steel and nonferrous metal making,continuous casting,metallurgy pressing machine
