Graphite Electrode Manufacturing Process
1.Raw Material
Use of high-quality calcined petroleum coke production materials
2.Crushing & Screening
They are broken needle coke in mechanical equipment and screening according to the formula after the proportion of the ingredients.
3.Kneading
Ingredients of the raw materials with a certain proportion of asphalt heated kneading, made with plastic paste.
4.Extruding
After kneading of the paste by temperature cooled to process, and forming into the compressor according to the requirements of product specifications.
5.Baking
Within the roasting road, will be “green” electrode roasting to the specified temperature, according to the requirements of the process. After roasting products with special dipping, density, and mechanical strength, improve product performance in order to improve the products and then to repeat the roasting of impregnated products.
6.Graphitization
Second after roasting the products within the graphitization resistance furnace power up to 3000 ℃, the carbon atoms rearrange into specific crystalline form structure, carbon into graphite.
