    Application of Graphite Electrode in Steelmaking Electric Arc Furnace

    Application of Graphite Electrode in Steelmaking Electric Arc Furnace

    Graphite electrodes should have at least the following properties on the smelting furnace. (1) Must be able to withstand the arc current required by the steelmaking process. (2) Continuous arc generation must be maintained. In addition, the electrode should be able to be used in a wide temperature range (that is, it can be used in a state of ...

    IntroductionAdvantagesDeficienciesIndustrial arc furnaces range in size from small units of approximately one ton capacity (used in foundries for producing cast iron products) up to about 400 ton units used for secondary steelmaking)(average is 80 to 120 MT). Arc furnaces used in research laboratories and by dentistsmay have a capacity of only a few dozen grams. Industrial electric arc furnace temperatures can be up to 1,800 °C (3,272 °F), while laboratory units can exceed 3,000 °C (5,432 °F).

Therefore, a 300-tonne, 300 MVA EAF will require approximately 132 MWh of ...預估閱讀時間: 7 分鐘Use of graphite electrodes in steel making - DanCrabonhttps://www.dancarbon.com/q/graphite-electrode/use-of-graphite-electrodes-229.html10/11/2020· The graphite electrode used in electric furnace steelmaking accounts for 70% ~ 80% of the total amount of graphite electrode. It USES the high-temperature heat source generated by the arc between the end of the electrode and the furnace burden to melt. The ore thermal furnace is mainly used to produce industrial silicon and yellow phosphorus.
