700mm Ultra High Power Graphite Electrodes
DC Furnaces 4.2μΩM 700mm Ultra High Power Graphite Electrodes
Introduction of Ultra High Power Graphite Electrodes
Ultra High Power Graphite Electrodes is a major conduction material used in the electric smelting industry,which has the properties ofsuperior electric conductivity,thermal conductivity,high mechanical strength,oxidation and corrosion resistance inhigh temperature,graphite electrode is typically used in EAF(for smeting stel),submerged-arc furnace(for producingferrodalloy,pure silicon.,phosphor,matte, calcium carbide,etc,and electric resistance furnace,such as graphitizationfurnace producing graphite electrodes,glass-melting furnace,electric furnaces producing carborundum etc.
Applications of Ultra High Power Graphite Electrodes
Ultra High Power Graphite Electrodes Is widely Used in EAF and LF for arc furnace,steel making, as well as in electric smelting furnace for producing industrial silicon, phosphorus, etc.
Instructions of usage for Ultra High Power Graphite Electrodes:
Notes of usage:
1.To Place the nipples, first use compressed air to clean the hole, then carefully screwed the nipples into it (do not damage the
thread).
2.To connect the electrodes, when there's 20-30mm distance between the two electrodes, using compressed air to clean the two
extremes.
3.Connector locations should be selected c-map.
4.When use the wrenches to connect electrodes, should be fully tighten to specified torque.
5.To avoid electrode broken, please remove the insulating material in the furnace.
