The main components of graphite electrodes are petroleum coke, needle coke, and asphalt. They possess excellent properties such as high electrical and thermal conductivity, corrosion resistance, thermal shock resistance, low resistivity, and low energy consumption. Graphite electrodes are used in steelmaking, yellow phosphorus production, and smelting of mineral raw materials such as corundum, and are suitable for ultra-high power electric arc furnace steelmaking.
