(1) For electric arc steelmaking furnace. Electric furnace steelmaking is a large user of graphite electrodes. Electric furnace steelmaking is carried out by using graphite electrode to conduct human current into the furnace and the high temperature heat source generated by the arc between the electric extreme and the charge.
(2) For mineral heating electric furnace. Mineral thermal electric furnace is mainly used for the production of industrial silicon and yellow phosphorus, etc., which is characterized by the lower part of the conductive electrode buried in the charge, forming an arc in the charge layer, and using the heat energy emitted by the resistance of the charge itself to heat the charge, which requires a higher current density of mineral thermal electric furnace requires graphite electrodes, such as the production of 1t silicon requires the consumption of graphite electrodes about 100kg, About 40kg of graphite electrodes are consumed for every 1t of yellow phosphorus produced.
(3) For resistance furnaces. Production of graphite products graphitization furnace, melting glass furnace and production of silicon carbide with the electric furnace are resistance furnaces, the furnace loaded material is both heating resistance and heated objects, usually, conductive graphite electrode embedded in the resistance furnace end of the furnace head wall, used here for graphite electrode discontinuous consumption.
(4) For the preparation of special-shaped graphite products. The blank of graphite electrode is also used for processing into various kinds of crucible, mold, boat and heating body and other special-shaped graphite products. For example, in the quartz glass industry, 10t of graphite electrode blank is required for every 1t of electric melting tube produced; For every 1t quartz brick produced, 100kg of graphite electrode blank is consumed.
