Use And Performance Of Graphite Electrodes

Uses and performance of graphite electrodes

(1) Used in electric arc steelmaking furnaces: Electric furnace steelmaking is a major user of graphite electrodes. Electric furnace steel production in my country accounts for about 18% of crude steel production, and graphite electrodes used in steelmaking account for 70% to 80% of the total graphite electrode consumption. Electric furnace steelmaking uses graphite electrodes to introduce current into the furnace and uses the high-temperature heat source generated by the arc between the electrode end and the charge to smelt.

(2) Used in electric arc furnaces: Electric arc furnaces are mainly used to produce industrial silicon and yellow phosphorus. Their characteristics are that the lower part of the conductive electrode is buried in the charge, an arc is formed in the charge layer, and the heat energy generated by the charge's own resistance is used to heat the charge. Electric arc furnaces that require higher current density require graphite electrodes. For example, about 100 kg of graphite electrodes are consumed for every ton of silicon produced, and about 40 kg of graphite electrodes are consumed for every ton of yellow phosphorus produced.
