Graphite electrodes are light in weight, have good thermal stability, and can be processed faster than copper materials. Graphite material is a better raw material for making electrodes. During the production process, graphite electrodes are formed through calcination, batching, kneading, pressing, roasting, graphitization and other processing steps, among which roasting requires the use of a roasting furnace for processing.
