UHP Graphite Electrode Overview
UHP Graphite Electrode - low resistance, high density
Ultra-high power graphite electrodes are mainly used in ultra-high power electric arc furnaces with current density greater than 25A/cm2.
UHP Graphite Electrode is used for steel recycling in the electric arc furnace industry. Its main component is high-value needle coke made from petroleum or coal tar pitch. Graphite electrodes have a cylindrical shape and threaded areas are machined at both ends. This allows graphite electrodes to be assembled into electrode columns using electrode joints.
To meet the requirements of higher working efficiency and lower total cost, large-capacity ultra-high power electric arc furnaces are becoming increasingly popular. Therefore, ultra-high voltage graphite electrodes with diameters of 500mm or more will dominate the market.
