Graphite electrodes are made from the best domestic petroleum coke and high-quality imported needle coke, and are widely used in arc furnaces for producing alloy steel and other metals, non-metals, etc. The products include: normal power, high power, quasi-ultra-high power, and ultra-high power graphite electrodes; sizes range from 300mm to 800mm. The products feature low resistance rate, good conductivity and heat conduction, good resistance to oxidation, strong resistance to thermal shock and mechanical vibration, high mechanical strength, and high precision of mechanical processing.
