Mô tả Sản phẩmCalcined Petroleum CokeCalcined Petroleum Coke (CPC) is a premium high-carbon industrial material produced by calcining green delayed petroleum coke at 1200–1400°C, eliminating volatile matter, moisture, and residual impurities. As a foundational feedstock for the global carbon industry, it is the core raw material for manufacturing graphite electrodes, aluminum electrolysis anodes, carbon blocks, and high-purity semiconductor thermal components. Its optimized crystalline structure, formed via high-temperature processing, delivers exceptional carbon purity, density, and conductivity, making it indispensable for energy-intensive metallurgical, chemical, and manufacturing processes. CPC bridges raw petroleum coke and high-performance carbon products, enabling efficient, low-cost, sustainable production across steel, aluminum, and advanced material sectors, supporting industrial decarbonization and operational efficiency worldwide.

Lợi thế sản phẩm Exceptional High-Temperature Resistance & Thermal StabilityCalcined petroleum coke features industry-leading carbon purity, typically 98.5–99.5% (up to 99.9% for premium grades), achieved through rigorous high-temperature calcination that removes volatile matter, sulfur, nitrogen, and heavy metal impurities. This ultra-low impurity profile is critical for aluminum electrolysis, where contaminants degrade anode performance and reduce aluminum purity; premium CPC cuts anode impurity-related defects by over 80%, boosting product quality and yield. In graphite electrode production, high-purity CPC (especially needle coke-based grades) ensures consistent conductivity and structural integrity, eliminating performance fluctuations in ultra-high-power electric arc furnaces. Unlike low-grade carbon materials, CPC's strict impurity control minimizes downtime, reduces maintenance costs, and meets strict industrial quality standards for high-performance carbon products.Exceptional Electrical & Thermal ConductivityCPC's optimized graphitic crystalline structure, formed during high-temperature calcination, delivers outstanding electrical and thermal conductivity, making it a top choice for conductive carbon applications. Its low electrical resistivity (as low as 400–500 μΩ·m for premium grades) minimizes power loss during current transmission, cutting energy consumption in aluminum electrolysis by 5–8% and in graphite electrode-based steelmaking by up to 12%. Its high thermal conductivity (100–150 W/(m·K)) enables efficient heat dissipation, preventing local overheating in high-current operations and extending the service life of carbon anodes and electrodes. Compared to alternative carbon materials, CPC maintains stable conductivity at extreme temperatures (up to 2500°C), ensuring consistent performance in harsh metallurgical environments, reducing energy costs, and supporting sustainable industrial production.High Density & Robust Mechanical StrengthCalcined petroleum coke exhibits exceptional bulk density and mechanical strength, a result of controlled high-temperature calcination that compacts its crystalline structure. Premium CPC boasts a real density of 2.0–2.15 g/cm³ and a compressive strength exceeding 30 MPa, making it highly resistant to mechanical stress, thermal shock, and abrasion during industrial processing. In aluminum electrolysis, high-density CPC anodes resist breakage during handling and long-term operation, reducing anode replacement frequency by 15–20% and cutting operational costs. In graphite electrode production, dense CPC feedstock enhances electrode structural integrity, preventing cracking under extreme arc temperatures and high mechanical loads in electric arc furnaces. This durability minimizes production interruptions, extends equipment service life, and delivers long-term cost savings for industrial operators.Excellent Thermal Stability & Chemical InertnessCPC demonstrates remarkable thermal stability and chemical inertness, even in extreme industrial environments. With a sublimation temperature exceeding 3600°C, it maintains structural integrity at temperatures up to 2500°C, resisting deformation, oxidation, and degradation in high-temperature metallurgical processes. At room temperature, it is chemically inert to most acids, alkalis, salts, and organic solvents, making it ideal for corrosive chemical and electrochemical applications. In high-temperature furnace linings and carbon refractory materials, CPC's inertness prevents chemical reactions with molten metals and slags, extending equipment service life by 2–3 times. Unlike reactive carbon materials, CPC's stability ensures consistent performance across long production cycles, reducing maintenance costs and operational risks for industrial facilities.CÂU HỎI THƯỜNG GẶP1.Are you Factory or Trading?
