Product Description Electrode Graphite with High Density Graphite Carbon Electrode ShpUsing coal pitch as binder, the graphite electrode which is mainly made of petroleum coke and needle coke is being made through the process of calcination, compounding, kneading, pressing, baking,impregnation, graphitization and machining. It is a conductor that release electrical energy to heat and melt the charge in the form of an electric arc in an electric arc furnace, and has the characteristics of low electrical resistivity, good electrical conductivity, low ash content, uniform structure, good oxidation resistance and high mechanical strength.Materials: Needle coke,CPC,Coal Pitch;Process: Petroleum coke calcined,Crush,Forming,Baking,Graphited,Machining;Grades: RP/HP/SHP/UHP;Application: Used in EAF/LF to make steel.Features:Low resistivityGood conductivityLow ashCompact and uniform structureGood oxidation resistanceMechanical strengthGraphite electrodes are used mainly in ladle furnaces, electric-arc furnace steelmaking,Yellow phosphorus furnace, Industrial silicon furnace or melting copper. They are presentlythe only products available that have high levels of electrical conductivity and the capabilityof sustaining the extremely high levels of heat generated in this demanding environment.Technical Characteristics of Graphite Electrode RP, HP, UHPProduct ParametersTechnical Characteristics of Graphite Electrode RP, HP, UHPNameUnitNominal 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.
