Product Description
UHP Graphite Electrode with High Quality for Electric Arc Furnace
Graphite Electrodes Production Process:
1. Raw Material: Petroleum coke, needle coke and coal pitch.
2. Crushing, Calcining, Medium Crushing and Screening:
Through crushing, calcining, medium crushing and screening processes, raw material is screened into specifed grain sizes. Then store the screened material in individual silos.
3. Forming: The kneaded material is formed to various size using an extrusion press by changing the extrusion press nozzle.
4. Keading, Dosing and Raymond Mill:
Kneading is the main factor which infuence the quality oo graphite electrode. Weight and mix coke according to the mixing standard based on quality design.
5. Baking/Rebaking: Improve the density and mechenical Strength.
6. Impreganation: Improve the thermal stability, mechnical strength and the electrical conductivity of the material.
7. Graphitization: The baked electrodes are graphitized for changing structure to obtain excellent.
8. Machining of Nipples and Graphite lectrodes
9. Finished Products & Package
Through above process, graphite electrode is finished, after inspection, it will be packed with wooeden pallet and braced strongly with high quality steel tape to be suitable for transportation. Technical Specification
