China Graphite Electrode suppliers DESCRIPTION: Graphite Electrodes are a high temperature resistant graphite conductive refractory material used in the metallurgical industry. Graphite Electrodes are made of petroleum coke, bituminous coke as aggregates, coal tar pitch as binders, after raw material calcination, crushing and milling, batching, kneading, molding, roasting, impregnation, graphitization and machining, which are also known as artificial graphite electrodes in order to distinguish from natural graphite electrodes made of natural graphite. FEATURE: Low resistivity High temperature strength Good thermal conductivity and electrical conductivity Low thermal expansion coefficient Low ash, its ash content is controlled within 0.3%. Dense and equal structure, Low graphite electrode consumption. Good oxidation resistance High mechanical strength Needle coke content accounts for 80% for UHP Grade, raw materials imported from Japan and South Korea APPLICATION: 1. Electric arc steelmaking furnace. 2. Ladle arc refining furnace. 3. Ore-heating furnaces. 4. Resistance furnaces SPECIFICATION: Technical specification of RP grade graphite electrode SpecificationUnitDiameter of RP Graphite Electrode 75-300mm350-450mm500-700mm Specific Resistance鈮?/pElectrode渭惟.m8.08.08.0 Nipple6.56.56.0 Bending Strength鈮?/pElectrodeMpa8.47.57.0 Nipple16.016.016.0 Elastic Modulus鈮?/pElectrodeGpa8.08.08.0 Nipple12.012.012.0 Bulk Density鈮?/pElectrodeg/cm31.601.601.60 Nipple1.741.741.74 C.T.E(100-600鈩?鈮?/pElectrode10-6/鈩?/p2.82.82.8 Nipple2.72.72.7 Ash鈮?/pElectrode%0.30.30.3 Nipple0.30.30.3 Graphite Electrode Size and Tolerance Nominal DiameterActual DiameterLength (mm)Tolerance MMInchPoppyMinesThe Minimum Size of The Black PartLengthShort Length 7537873721400/1600卤 100-275 100410398971400/1600 13051321271261400 15061541491461400/1600/1800 17571801741721400/1600 20082052001971600/1800 22592302252221600/1800 250102552512481600/1800 300123073022991600/1800/2000 350143573523491600/1800/2000 400164094034001600/1800/2000/22000 450184604544511600/1800/2000/22000 500205115055021600/1800/2000/22000 550225625565531800/2000/2200/2400 600246136076042000/2200/2400/2700 650266636596562000/2200/2400/2700 700287147107072000/2200/2400/2700 Allowable Capacitance Flow of the electrode Nominal diameterAllowable capacitance flow (A)Electric current density MillimeterInch 753"1000-140022-31 1004"1500-240019-30 1506"3000-450016-25 2008"5000-690015-21 25010"7000-1000014-20 30012"10000-1300014-18 35014"13500-1800014-18 40016"18000-2350014-18 45018"22000-2700013-17 50020"25000-3200013-16 55022"28000-3400012-14 60024"30000-3600011-13 65026"32000-3900010-12 70028"34000-420009-11China Graphite Electrode suppliers website:http://www.jilincarbonnewmaterials.com/graphite-electrode/
