The waste graphite electrode is used for: making small graphite processing workpiece, grinding for carburizing, but also grinding for conducting materials. There's a metal in the electrode that's useful. It can be pulverized to make a mechanical lubricant, something heat-resistant.
First is the crushing section, the second is the graphite grinding section, the third is the powder section. Graphite electrode is mainly used in electric furnace steelmaking. Electric furnace steelmaking is the use of graphite electrode into the furnace current, strong current at the lower end of the electrode through the gas arc discharge, use the heat generated by the arc to smelt.
