High Quality HP UHP450 Carbon Graphite Electrodes for Eaf Smelting¹

Product Description High Quality HP UHP450 Carbon Graphite Electrodes for EAF SmeltingProduct DescriptionGraphite Electrode is made of high-quality low ash materials, such as petroleum coke, needle coke and coal pitch.after calcining,burdening,kneading,forming,baking and pressure impregnation, graphitization and then precision machined with professional CNC machining.such of the products own characteristics with low resistivity, good electrical conductivity ,low ash, compact structure,good anti oxidation and high mechanical strength, Widely used in LF, EAF for steel making industry, Non-ferrous industry, silicon and phosphorus industry.so it is the best conductive material for electric arc furnace and smelting furnace. Application Of Graphite electrodes: Graphite electrodes are used mainly in ladle furnaces,electric-arc furnace steelmaking,Yellow phosphorus furnace , Industrial silicon furnace or melting copper. They are presently the only products available that have the high levels of electrical conductivity and the capability of sustaining the extremely high levels of heat generated in this demanding environment.High Quality Needle Coke in HP&UHP graphite electrode,ensure the electrode application is perfect. Graphite electrodes are also used to refine steel in ladle furnaces and in other smelting processes. Characteristics Of Graphite electrodes: Our graphite electrodes are with low electric resistance, high density, high anti-oxidation capability, precise machining accuracy, especially with low sulphur and low ash will not give steel second timeSpecification The Length & Diameter & Permissible Deviation of Graphite Electrod Nominal DiameterActual DiameterLength (mm)ToleranceMMInchPoppyMinesThe Minimum Size Of The Black PartLengthShort Length7537873721400/1600± 100-275100410398971400/16001305132127126140015061541491461400/1600/180017571801741721400/160020082052001971600/180022592302252221600/1800250102552512481600/1800300123073022991600/1800/2000350143573523491600/1800/2000400164094034001600/1800/2000/22000450184604544511600/1800/2000/22000500205115055021600/1800/2000/22000550225625565531800/2000/2200/2400600246136076042000/2200/2400/2700650266636596562000/2200/2400/2700700287147107072000/2200/2400/2700★ Technical Characteristics of Graphite Electrode RP, HP, UHP NameUnitNominal DiameterUHP Ultra-High-PowerHP SuperstrongRP Conventional Power≤Φ400≥Φ450≤Φ400≥Φ450≤Φ300≥Φ350ResistivityElectrodeΜΩ · m≤5.5≤6.5≤8.5Nipple≤4.5≤5.5≤6.5Flexural StrengthElectrodeMPa≥11.0≥10.5≥9.8≥8.5≥7.0Nipple≥20.0≥16.0≥15.0Elastic ModulusElectrodeGPa≤14.0≤12.0≤9.3Nipple≤18.0≤16.0≤14.0DensityElectrodeg / cm3≥1.66≥1.67≥1.621.6≥1.53≥1.52Nipple≥1.75≥1.73≥1.69Coefficient Of Thermal ExpansionElectrode10-6 / oC≤1.5≤2.4≤2.9Nipple≤1.4≤2.2≤2.8ASH%≤0.3≤0.3≤0.5Note: 1.Koeffitsient ash content and thermal expansion as the reference index, the coefficient of thermal expansion (100 oC ~ 600 oC), Custom manufacturing. ★ Technical Characteristics of High Density Graphite Electrode (HD) NameUnitNominal Diameter75-200 mm250-300mm400-500mmtop gradefirst gradetop gradefirst gradetop gradefirst gradeResistivity (Not More Than)ElectrodeΜΩ · m8.09.08.09.08.09.0Nipple7.57.57.5Flexural Strength(not less than)ElectrodeMPa1098Nipple131313Elastic Modulus(no more)ElectrodeGPa121212Nipple141414Density(not less than)Electrodeg / cm31.581.581.58Nipple1.681.681.68Coefficient Of Thermal Expansion (No More)Electrode10-6 / oC2.7.2.7.2.7.Nipple2.52.52.5Ash Content (not more than)%0.30.30.5Note: 1.
