Good Quality Hot Sale UHP/HP/RP Graphite Electrode for Steel Making

Type: Graphite Electrodes

Composition: SiC

Carbon Content: Medium-Carbon

Grade: UHP

Forming Way: Extruded Graphite

Graphite ElectrodeGraphite electrode is made from the domestic first class petroleum coke and high quality needle coke and widely used in the electric arc furnaces for production of alloy steels, metal and other nonmetallic materials, etc. The Graphite electrodes include: regular power, high power, ultra high power and square electrode. The range of diameters covers from 200mm to 800mm. Our products own the following characteristics: low electric resistivity, good electrical and thermal conductivity, high oxidation resistance, greater resistance to thermal and mechanical shock, high mechanical strength, high machining accuracy.CNBM and its partner have 4 production bases and the annual production capacity of graphite electrodes is 60,000 MT.Technical Specification:ItemUnitRPHPUHP250-400450-800300-400450-700300-400450-700Electric ResistivityElectrodeμΩ.m7.5-8.67.5-8.85.5-6.85.5-7.04.6-6.04.8-6.2Nipple4.5-5.54.0-5.03.5-4.5Bending StrengthElectrodeMPa≥8.0≥11.0≥11.0Nipple≥15.0≥16.0≥18.0Elastic ModulusElectrodeGPa≤9.0≤11.0≤13.0Nipple≤13.0≤14.0≤15.0Bulk DensityElectrodeg/cm31.55-1.651.63-1.731.65-1.75Nipple1.70-1.751.73-1.801.75-1.82AshElectrode%≤0.3NippleCTE(100-600)ºCElectrode10-6/ºC2.00-2.501.80-2.001.30-1.50Nipple 1.50-1.801.50-1.801.20-1.40Graphite Electrode Process Flow&Dimension Drawing of Nipples Allowable Capacitance Flow of the Electrode&Standard Sizes and TolerancesCompany ProfileCNBM INTERNATIONAL CORPORATIONBuild your world with our materials.We are a primary subsidiary of China National Building Material Group Co., Ltd.CNBM Group is a central government-owned enterprise and a Fortune Global 500 company (Ranking 203th in 2019).
