Superiority
Graphite Electrode takes the high quality petroleum coke, needle coke, coal tar as raw material after the process of kneading, molding, baking and pressing. And then it was treated with impregnation and subsequent graphitized at 2500ºC, was produced by mechanical processing again.
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.Forming
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.
The graphite electrodes are primarily used to carry the electricity that melts scrap iron and steel in electric arc furnaces. As an increasing proportion of global steel is made using electric arc furnaces, the secondary production of steel becomes the major consumption of graphite electrodes. Additionally, the graphite electrode is also used in melting products in smelting furnaces, non-ferrous metals, ceramic products, and even the waste recycling industry. The demand for graphite electrodes is majorly dependent on its application in manufacturing steel through smelting by using an electric arc furnace (EAF). Steel manufacturers are shifting towards electric arc furnaces over the blast furnaces, owing to the advantages offered by EAF such as low cost of establishment, higher production flexibility, and low CO2 emissions.
