Ultra-high Power Graphite Electrode

Ultra-High Power Graphite Electrode
Ultra-High Power 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 an electrode nipple.


In order to meet the requirement of higher work efficiency and lower total cost, large capacity ultra-high power arc furnaces are becoming more and more popular. Because of this, Ultra-High Power graphite electrodes with diameters of over 500 mm will dominate the market.
