Calcined Petroleum Coke (For Steel & Aluminium)
Calcined petroleum coke is a kind of petrochemical product and its raw materials is green petroleum coke. It is widely used to produce graphite electrode, graphite blocks, brake pads and other carbon products. It can also be used as carbon additive in steel making, nodular iron casting and aluminum making.
The main function of Calcined petroleum coke is applied in the production of anodes during Aluminum Smelting process with a percentage of about 70 – 80%.
1. Moisture content: The total moisture index shall be as low as possible as the hydrogen content in molten metal will increase caused by the brought water. It shall be less than 1%. (We normally limit it to ≤0.5%)
2. Ash content: The lower, the better. Ash increases impurities and inclusions of the molten metal. There’s big difference between different materials, range from 0.5-1% (calcined petroleum coke), 1.0-5.0%(calcined anthracite coal) to 9.0-14% (calcined coal coke).
3. Volatile matter: It’s the Invalid part of the carburizer, which depends on the calcination, coking temperature and treatment process. It also increases gas content of molten metal. The properly treated volatile matter is below 0.5% (calcined petroleum coke).
4. Fixed carbon: The fixed carbon content is the real effective part of the carburizer. Generally speaking, the higher, the better. In fact, fixed carbon content is decided by a comprehensive indicator concerning with ash content and volatility. The lower the ash content and volatility, the higher the fixed carbon content. Carburizers can be divided into different grades according to the fixed carbon index value, e. g. 95%, 98.5%, 99%, etc.
5. Sulfur is a crucial element by impacting the quality of metal. The lower the sulfur, the better quality of the carburizer. We can limit it within 0.05% in all-graphite petroleum coke, while it ups to 0.4% in calcined coal coke.
