Graphited petroleum coke is an important casting raw material. Different granularities of graphited petroleum coke will produce different effects when put into production, so when purchasing, you should first clarify the use of the target, according to the use of the target to determine the size of the particle size.
Select the size according to the application scenario
Carbonizer use: If it is mainly used as a carbonizer in metallurgy, casting, and precision casting, 1-5mm graphitized petroleum coke is a more common choice. For example, the graphitized petroleum coke carbonized produced by Zhong Carbon Energy Co., Ltd. has a conventional particle size of 1-5mm, and this size of carbonized can be better integrated into the furnace to uniformly increase the carbon content of the castings and improve the mechanical properties of the castings.
Electrode manufacturing applications: Larger sizes of graphitized petroleum coke may be required for the production of large cathode blocks, large carbon electrodes, large graphitized electrodes, and high-performance electrode pastes. However, after further processing, 1-5mm graphitized petroleum coke can also be used to make small electrodes or electrode paste and other products.
Making high-temperature crucibles: when used to make high-temperature crucibles for smelting, 1-5mm graphitized petroleum coke can be made into suitable crucible shapes and sizes through processes such as press molding to meet the requirements of containers in high-temperature environments.
Customized size: different suppliers may offer graphitized petroleum coke products in different sizes, which can also be customized according to customers' requirements. For example, Zhong Carbon Energy Co., Ltd. may provide graphitized petroleum coke with a granularity of 1-3mm, 1-4mm, 1-5mm or processed according to customers' requirements. When choosing a supplier, make sure that the supplier can provide a product that meets the size of your specific needs.
Applicable scenarios of large particle size graphitized petroleum coke
Electrode Manufacturing: In the production of normal power graphite electrodes, larger particle-size petroleum coke can be used to improve the conductivity of the electrode. Larger particle size petroleum coke helps to form a more uniform graphite crystal structure, thus improving the conductivity and mechanical strength of the electrode.
Chemical production: High-sulfur, common raw coke with larger particle size is used in chemical production, such as the manufacture of calcium carbide and silicon carbide. These materials require larger particles to improve reaction efficiency and reduce dust.
Metal Casting: When used as a fuel, large particle-size petroleum coke provides more stable combustion and is suitable for metal casting and other processes that require a high-temperature environment.
Applicable scenarios for small particle size graphite petroleum coke
Ultra-high power graphite electrodes: In the production of ultra-high power graphite electrodes, petroleum coke with a smaller particle size is needed to improve the density and strength of the electrodes. Smaller particle size petroleum coke can reduce the generation of porosity and cracks, and improve the density and strength of graphite electrodes, thus improving their stability and service life under high temperatures.
Carbonizer: Small particle size graphitized petroleum coke carbonized (e.g. 1-5mm) is widely used in metallurgy, casting, and precision casting, which can uniformly increase the carbon content of the castings, improve the mechanical properties of the castings, and increase the hardness and wear resistance.
High-temperature crucible: small particle size graphitized petroleum coke can be used to make a high-temperature crucible, its uniform particles help to form a dense structure and improve the crucible's high-temperature resistance and mechanical strength.
Battery industry: Small particle-size graphitized petroleum coke can be used in the production of electrodes for the battery industry, providing the necessary electrical conductivity.
In summary, large particle size graphitized petroleum coke is suitable for electrode manufacturing, chemical production of calcium carbide, silicon carbide, etc., metal casting, and other scenarios where larger particles are needed to improve electrical conductivity or combustion stability. Small particle size graphite petroleum coke is suitable for ultra-high power graphite electrodes, carbon enhancers, high-temperature crucibles, the battery industry, and other scenarios that require high density, high strength, and uniform structure.
