DESCRIPTION
Calcined petroleum coke is a critical ingredient in the production of carbon electrodes used in the smelting of aluminum. Carbon electrodes are used to conduct electricity in the aluminum smelting process, while calcined petroleum coke is used as a carbon source for these electrodes.
The following chart shows the different stages of calcined petroleum coke production:
1. Extraction: Raw petroleum coke is extracted from oil refineries.
2. Calcining: The raw petroleum coke is heated in a furnace to remove moisture and volatile organic compounds. This process is called calcining and produces calcined petroleum coke with a carbon content of approximately 99%.
3. Crushing and screening: The calcined petroleum coke is crushed and screened into different sizes.
4. Blending: The appropriate size fractions are blended to meet the specific requirements of carbon electrode production.
5. Briquetting: The blended calcined petroleum coke is compacted into blocks or briquettes, which are used as the primary raw material in the production of carbon electrodes.
Overall, calcined petroleum coke is a crucial component of the aluminum smelting process, as it provides the carbon source required to produce high-quality carbon electrodes that can conduct electricity and withstand high temperatures.
