graphite electrode RP HP UHP grade

2.Graphite electrode is made of high quality calcined petroleum coke,imported needle coke and modified coal asphalt,the grade are RP,HD(impregnation),HP and UHP graphite electrodes,the specification is Ø75-700mm. Graphite electrode produced by our company has the advantages of low resistivity,high electrical conductivity and thermal conductivity,good oxidation resistance,good thermal shock resistance,high mechanical strength,easy to machine,etc. Graphite electrode is widely used to smelt the steel,alloy steel and other metal or nonmetal material in electric arc furnace. Properties: graphite electrodelow resistivity, graphite electrodegood conductivity,graphite electrode low ash, graphite electrodeuniform and graphite electrodecompact structure,graphite electrode good oxidation resistance, graphite electrodehigh mechanical strengt. In the steelmaking process, iron scrap gets melted in an electric arc furnace and recycled. Graphite electrodes, a kind of conductor, are an essential component in this kind of furnace. They can melt scrap at a temperature of about 1600℃. The electric arc furnace method recycles used iron scrap by melting it in an electric arc furnace. It is the graphite electrodes inside the furnace that actually melt the iron. Graphite has high thermal conductivity and is very resistant to heat and impact. It also has low electrical resistance, which means it can conduct the large electrical currents needed to melt iron. In recent years, graphite electrodes have been made even more efficient: they can now conduct even higher currents and more power.
