High Quality Graphite Electrode For EAF Furnace
Packaging Details:
1: Wooden crates with steel straps; wooden crates treated with "IPPC" label
2: standard export fumigated wooden box with steel strip fixed outside
3: In wooden case, each nipple must be packed in cardboard box.
Each electrode and nipple to preset at one end. The head of the preset nipple shall be covered by cardboard cap supported by wooden plate from both ends to avoid damage to the threads during transportation

Production Description:
Graphite electrode is made from the domestic first 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, super high power, ultra high power and square electrode. The range of diameters covers from 200mm to 700mm. Our products own the following characteristics: low electric resistance, good electric and thermal conductivity, high oxidation resistance, greater resistance to thermal and mechanical shock, high mechanical strength, high machining accuracy.
PRODUCT DETAILS
Graphite electrode is a major conduction material used in the electric smelting industry, which has the properties of superior electric conductivity, thermal conductivity, high mechanical strength, oxidation and corrosion resistance in high temperature. Graphite electrode is typically used in EAF(for smelting steel),submerged-arc furnace(for producing ferrodalloy, pure silicon, phosphor, matte, calcium carbide, etc.)And electric resistance furnace furnace, such as graphitization furnace producing graphite electrodes, glass-melting furnace, electric furnaces producing carborundum, etc.
