The manufacturer has been built since 1992.We mainly do the domestic market in the past time. Our company begin exploit the oversea market since 2015.Has exported to 19 countries.Honesty is the principle of our factory. We insist on quality first. We adhere to customer first. We are responsible for we sold of each product, to take responsibility for every customer.We are a manufacturer and trading combo,special in the carbon&graphite procuts for 24 years. The main products is EP(electrode paste),GE(graphite eletrode), (CPC)calcined petroleum coke, and also do trading for other carbon and graphite items. Our carbon and graphite items have passed the testing specific carbon testing according to JB/T6773-2011.We're sure that the material is in striectly accordance to REACH regalation for EU market.Graphite Electrode Graphite electrode, mainly from the domestic petroleum coke and imported needle coke, is widely used in electric arc furnace, ladle furnace, submerged arc electric furnace for the production of alloy steel, metal and nonmetallic materials. Our graphite electrodes include regular power, high power, super high power and ultra high power. They are characterized by low resistivity, good electric and thermal conductivity, high resistance to oxidation and thermal shock, high mechanical strength, ect. Our plant offers various dimensions and grades to meet customers' requirements for the specific applications.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 strength.Specification:ItemUnitGraphite ElectrodeRPHPUHPφ300-φ800mmφ300-φ800mmφ300-φ500mmφ550-φ800mmTypical ValueTypical ValueTypical ValueTypical ValueResistivityElectrodeμΩm7.0-10.05.8-6.64.5-5.84.6-5.8Nipple4.0-4.53.5-4.03.5-4.03.5-4.0Modulus of RuptureElectrodeMpa8.0-10.010.0-13.010.0-14.010.0-14.0Nipple19.0-22.020.0-23.020.0-24.022.0-26.0Young's ModulusElectrodeGPa7.0-9.38.0-12.09.0-13.010.0-14.0Nipple12.0-14.014.0-16.015.0-18.016.0-19.0Bulk DensityElectrodeg/cm31.53-1.561.64-1.681.68-1.741.70-1.74Nipple1.70-1.741.75-1.801.78-1.821.80-1.84CTE (100-600ºC)Electrode10-6/ºC2.2-2.61.6-1.91.1-1.41.1-1.4Nipple2.0-2.51.1-1.40.9-1.20.9-1.2Ash%0.50.30.30.3Current load and current density:DiameterRPHPUHPmmCurrent Load (A)Current Density(A/cm³)Current Load (A)Current Density(A/cm³)Current Load (A)Current Density(A/cm³)2005000-690015-215500-900018-252256100-860015-216500-1000018-252507000-1000014-208000-1300018-258100-1220020-3030010000-1300014-1813000-1740017-2415000-2200020-3035013500-1800014-1817400-2400017-2420000-3000020-3040018000-2350014-1821000-3100016-2425000-4000019-3045022000-2700013-1725000-4000015-2432000-4500019-2750025000-3200013-1630000-4800015-2438000-5500018-2755032000-4000013-1637000-5700015-2342000-6600017-2660038000-4700013-1644000-6700015-2349000-7600017-26Product ProcessingCustomer negotiationProduct PackingFAQQ:Deliverytime?A:The delivery time is about 15-30days after receipt of payment.Q:Price?A:Beforeinquiryustheprice,plsbekindlysendusthedetaildataofthematerialyouneed.I willgiveyouourbestprice.Q:Quality?A:You can get the best qualitywhich you need with the equal price.
