Graphite Electrode The Graphite electrodes are produced through calcined material under high pressure in vacuum impregnation and then Graphitized at Graphitization Furnace; finally they are machined.The electrodes are supplied 100-700mm diameter with specification RP(Regular Power), HP and UHP. High Power grade is for foundry operations, for the ladle furnace and occasionally for the electric arc furnace operations, if the furnace parameters are suitable. Ultra High Power grade is suitable for the electric arc furnace (EAF) operations and the ladle furnace operations with heavy current loads.
