Graphite Electrodes
Graphite electrodes are mainly used in the production or recycling of steel. In this process, steel scrap is melted in a large crucible (furnace) by the heat of an electric arc, which is why these furnaces are called electric arc furnaces. Approximately 1/3 of the world’s steel is produced in this way, making it the largest recycling process in the world. In contrast to the alternative route, steel production by means of iron ore, production by means of electric arc furnaces avoids about 80% of direct CO2 emissions per ton of steel.
