High Fixed Carbon Low Sulphur Graphite Petroleum Coke For Foundry

High Fixed Carbon Low Sulphur Graphite Petroleum Coke For Foundry

Graphite petroleum coke is a high-quality carbon material derived from petroleum refining. It is often used as a carbon additive in various industries, including steelmaking, foundry, and electrodes manufacturing. Here are some common specifications and properties of graphite petroleum coke:

1. Fixed Carbon Content: Graphite petroleum coke typically has a high fixed carbon content, ranging from 98% to 99.5%. This high carbon content makes it an excellent carbon additive, as it provides carbon for the desired chemical reactions in various industrial processes.

2. Sulphur Content: The sulphur content in graphite petroleum coke is relatively low, typically below 0.5%. Low sulphur content is desirable in applications where sulphur impurities may negatively impact the final product's quality or where strict environmental regulations must be met.

3. Volatile Matter: Graphite petroleum coke has a relatively low volatile matter content, typically ranging from 0.5% to 2.5%. Low volatile matter ensures that the coke burns efficiently and does not produce excessive smoke or emissions during use.

4. Ash Content: The ash content in graphite petroleum coke is usually low, typically below 0.5%. Low ash content is desirable to minimize impurities and maintain the purity of the carbon material.

5. Particle Size and Distribution: Graphite petroleum coke is available in various particle sizes and distributions, depending on the specific application requirements. Different particle sizes can affect the coke's reactivity, density, and handling characteristics.

6. Electrical Conductivity: Graphite petroleum coke exhibits high electrical conductivity due to its high carbon content. This property makes it suitable for use in applications where electrical conductivity is required, such as in the production of carbon electrodes.

7. Thermal Conductivity: Graphite petroleum coke has good thermal conductivity, allowing it to transfer heat efficiently. This property is beneficial in applications where heat transfer is essential, such as in the steelmaking process.

8. Hardness: Graphite petroleum coke is relatively hard and resistant to breakage. This hardness helps maintain the coke's structural integrity during handling, transportation, and use.

9. Chemical Stability: Graphite petroleum coke is chemically stable and resistant to most chemicals, ensuring its durability and suitability for use in various harsh environments.

These specifications and properties can vary depending on the specific grade, manufacturing process, and supplier of graphite petroleum coke. It is advisable to consult the product datasheets or contact the manufacturers or suppliers for precise information regarding a particular grade or product.
