What are the applications of graphite electrodes?
(1) Graphite electrodes for electric arc steelmaking furnaces
Electric furnace steelmaking is a major user of graphite electrodes. my country's electric furnace steel production accounts for about 18% of crude steel production, and graphite electrodes for 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) Graphite electrodes are used in electric furnaces
Oil-fired electric 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 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.
(3) Graphite electrodes are used in resistance furnaces
Graphitization furnaces for producing graphite products, melting furnaces for melting glass, and electric furnaces for producing silicon carbide are all resistance furnaces. The materials loaded in the furnace are both heating resistors and heated objects. Usually, the graphite electrodes used for conductivity are embedded in the furnace head wall at the end of the resistance furnace, and the graphite electrodes used here are not continuously consumed.
(4) Graphite electrodes are used to prepare special-shaped graphite products
Graphite electrode blanks are also used to process various special-shaped graphite products such as crucibles, molds, boats and heating elements. For example, in the quartz glass industry, 10 tons of graphite electrode blanks are required for every ton of electric melting tube produced; 100 kg of graphite electrode blanks are required for every ton of quartz brick produced.
