Electric furnace steelmaking is a major user of graphite electrodes. The output of electric furnace steel in China accounts for about 18% of the crude steel output, and graphite electrodes for steelmaking account for 70% to 80% of the total consumption of graphite electrodes. Electric furnace steelmaking uses graphite electrodes to introduce an electric current into the furnace, and uses the high-temperature heat source generated by the electric arc between the electrode ends and the furnace charge to conduct smelting.
