Ultra-High-Power UHP700 UHP600 HP450 RP150 Graphite Electrode Used In Steel Making
Graphite electrodes are mainly used in metallurgy, chemical industry and other industries, with specific applications as follows:
Metallurgy: Electric furnace steelmaking is a major user of graphite electrodes. In China, the output of electric furnace steel accounts for about 18% of the crude steel production, and the graphite electrodes used in steelmaking account for 70% to 80% of the total consumption of graphite electrodes. Electric furnace steelmaking utilizes graphite electrodes to introduce current into the furnace, and utilizes the high-temperature heat source generated by the arc induced between the electrode tip and the charge to carry out smelting.
Chemical industry: Ore-smelting electric furnaces are mainly used for producing industrial silicon and yellow phosphorus. The characteristics are that the lower part of the conductive electrode is buried in the charge, forming an arc within the charge layer, and utilizing the heat energy generated by the resistance of the charge itself to heat the charge. Ore-smelting electric furnaces that require higher current density need to use graphite electrodes, for example, about 100 kg of graphite electrodes are consumed for every 1t of silicon produced, and about 40 kg of graphite electrodes are consumed for every 1t of yellow phosphorus produced.
