Graphite electrode is a carbon product made by roasting amorphous carbon in a graphitization furnace.
Graphitization refers to a high-temperature treatment process in which carbon products are heated to above 2300°C in a high-temperature electric furnace to convert amorphous carbon into graphite with a three-dimensional ordered plane hexagonal grid layered structure.
Graphitization furnace is usually used, and the furnace types include Acheson graphitization furnace and internal heat series connection (LWG).
