Graphite Electrode

High power grate electrode is made of high quality petroleum coke or low-level needle coke, need to be impregnated, its sical and mechanical properties is higher than regular power grate electrode(RP), such as low resistivity, allows a larger current density, but lower than ultra high power grate electrode(UHP).-------------------------------------------------------------------------Material: High quality petroleum coke or needle cokeDiameter: 200mm-700mmBulk Density：1.63-1.73                Resistivity：6.0-6.5Standard: IEC60239, EN60239:2005   ---------------------------------------------------------------------------------------------------------- Tel/pan>
