Applications Of Furnace Graphite Electrode
Furnace Graphite Electrodes are used in electric arc steelmaking furnaces. Electric steelmaking is the main use of graphite electrodes. Electric furnace steelmaking is the use of graphite electrodes to the furnace into the current, the use of electrodes between the point part and the charge triggered by the arc of the high-temperature heat source to exercise.
Furnace Graphite Electrodes are used in mineral heat electric furnaces. Mineral heat furnace is mainly used for the production of industrial silicon and yellow phosphorus, etc., which is characterized by the conductive electrode of the lower part of the buried in the furnace guess, in the layer of material to form an arc, and the use of the charge itself the resistance of the heat energy announced to heat the charge, which requires a higher current density of the mineral heat furnace need to be used with graphite electrodes.
