Application Details
♦ Suitable Products
In the field of specialty carbon products, calcined petroleum coke (especially needle coke) and all-graphite petroleum coke are core raw materials, while semi-graphite petroleum coke is mostly used as an auxiliary ingredient in low- to mid-range products.
♦ Application Scenarios
1. Calcined Petroleum Coke (Core Raw Material, Preferred for High-End Products)
•Main Product Types
Graphite Electrodes, Ultra-High Power Graphite Electrodes, Carbon-Carbon Composite Materials, Graphite Crucibles, Nuclear Graphite, Graphite Billets for Lithium-ion Battery Anodes
•Core Application Scenarios
Graphite Electrode Production
Made from needle coke through calcination, forming, roasting, graphitization, and machining. Used in electric arc furnace steelmaking and refining furnaces, it provides conductivity, heat generation, and high-temperature load-bearing capacity, making it a key consumable in steel smelting.
Carbon-Carbon Composite Materials
Used as the impregnation carbon source for carbon fiber preforms, after high-temperature carbonization and graphitization, it is used to produce high-performance materials for aerospace (rocket nozzles, aircraft brake pads) and semiconductor (single crystal furnace hot zone components), possessing high-temperature resistance, high strength, and low density characteristics.
Nuclear Graphite and Special Crucibles
High-purity calcined petroleum coke, after purification and graphitization, is used as a moderator in nuclear reactors or to manufacture graphite crucibles for smelting precious and rare metals, relying on its low impurities and high corrosion resistance.
•Key Technical Requirements
Needle coke is preferred, and it need meet the following requirements:
► Fixed carbon ≥ 98% ► Sulfur ≤ 0.03%, ash content ≤ 0.02%
► True density ≥ 2.1 g/cm³ ► Coefficient of thermal expansion ≤ 1.0 × 10⁻⁶/℃
The particle morphology should be fibrous to ensure the structural strength and electrical and thermal conductivity of the finished product.
2. All-graphite petroleum coke (highly graphitized raw material, ingredient for mid-to-high-end products)
•Main Product Types
Medium-power graphite electrodes, graphite molds, graphite heat exchangers, conductive graphite blocks, and electrical discharge machining (EDM) graphite electrodes.
•Core Application Scenarios
Replacing some needle coke
In the production of medium-power graphite electrodes, they are used in combination with calcined needle coke, utilizing their high graphitization degree (≥95%) to improve the conductivity of the products while controlling raw material costs.
EDM Graphite Electrode Manufacturing
Leveraging their low resistivity (≤15μΩ・m) and high purity (fixed carbon ≥99%), graphite electrodes for EDM are manufactured for precision machining of mold cavities, offering high discharge efficiency and low loss.
Specialty Graphite Components
Producing acid and alkali resistant graphite heat exchangers for the chemical industry or conductive graphite blocks for the metallurgical industry, relying on their stable chemical properties and conductivity.
•Key Technical Requirements
► Fixed carbon ≥ 99% ► Sulfur ≤ 0.05%
► Ash content ≤0.3% ► Graphitization degree ≥95%
3. Semi-graphite petroleum coke (auxiliary raw material, low-end product ingredient)
•Main Product Types
Ordinary graphite crucibles, carbon blocks, metallurgical graphite liners, low-end conductive carbon bricks.
•Core Application Scenarios
As a low-cost filler, it is used in combination with calcined petroleum coke to produce ordinary graphite products with low performance requirements, such as small graphite crucibles for smelting non-ferrous metals and ordinary carbon blocks for blast furnaces. Its main function is to supplement carbon content, adjust product density, and reduce overall raw material costs.
•Key Technical Requirements
► Fixed carbon ≥ 95% ► Sulfur ≤ 0.3%
► Ash content ≤2.0% ► Graphitization degree ≥50%
