Product Name: HP UHP 250mm1800mm Graphite Electrode for Smelting Model NO.: RP HP UHP Crystal Morphology: Compact Crystalline Graphite Forming Way: Extruded Graphite Grade: UHP Carbon Content: High-Carbon Composition: Petroleum Coke & Needle Coke Type: Graphite Electrodes Application: Eaf and Lf Furnace Use: Steel Making Trademark: Rongxing Transport Package: Wooden Pallets with Steel Strips Specification: 200-600mm Origin: China HS Code: 8545190000 Product Description Company Description:Rongxingcarbon established in 1992, after twenty years development, we has formed our own production system: electrode paste and recarburizers (including anthracite carburant, calcined petroleum coke carburant, graphite recarburizer) are core products, and also produce pre-baked anode, anode scrap, carbon brick coal and petroleum coke.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.Annual output:40,000tons graphite electrode200,000tons electrode paste200,000tons calcined petroleum coke Product DetailsIntroduction: graphite electrode, mainly petroleum coke, needle coke as raw material, coal pitch as binder, calcination, ingredients, kneading, molding, baking and graphitization, machining and made, which is released in electric arc furnace in the form of arc conductor of electricity to heat melting furnace charge, graphite electrodewith low resistivity,graphite electrode good conductivity, graphite electrodelow ash, graphite electrodeuniform and graphite electrodecompact structure, good oxidation resistance, high mechanical strength, etc. Category: Regular powder electrode RP, high-power electrode HP, ultra-high-power electrode UHP...
