Graphite electrodes are mainly used for the production or recovery of steel. The scrap is melted by the heat of
the electric arc in a large crucible (furnace), which is why these furnaces are called electric arc furnaces. About one-third of the world's steel is produced
in this way, making it the largest recycling process in the world. Compared with the alternative route, the production of steel by iron ore and the production
of steel by electric arc furnace avoid about 80% of direct carbon dioxide emissions. So graphite electrode plays an important role.
