Graphite electrode, mainly uses petroleum coke, needle coke as raw material, coal pitch as binder, is made through calcination, ingredients, kneading, molding, baking, graphitization and machining, which is released electricity in electric arc furnace in the form of arc conductor to heat and melt furnace charge. It has the characteristics of low resistivity, good conductivity, low ash, uniform and compact structure, good oxidation resistance and high mechanical strength. Ultra high power graphite electrodes refer to graphite electrodes that allow the use of current densities greater than 25 A / cm2. UHP Graphite Electrodes are mainly used in ultra-high power electric furnace and ladle furnace.
