2-5mm Semi Graphitized Petroleum Coke

2-5mm semi-graphitized petroleum coke is a high-performance carbon raiser made from high-quality raw petroleum coke through a medium-high temperature graphitization process. The particle size is strictly controlled within the 2mm-5mm range. Compared to ordinary calcined petroleum coke and fully graphitized petroleum coke, it produces a partial graphite crystal structure within the carbon molecules, achieving excellent carbon collection, stable particle hardness, and high cost-effectiveness, making it suitable for mainstream metallurgical smelting conditions.

Core Physicochemical Indicators (Batch Performance Stable)

- Fixed Carbon: ≥98.5%

- Sulfur Content: ≤0.03%

- Ash Content: ≤0.7%

- Volatile Matter: ≤0.8%

- Particle Size: 2-5mm

- Moisture: ≤0.5%

Main Application Areas

Foundry Industry (Core Application)

Suitable for ductile iron, gray cast iron, alloy castings, and precision automotive castings. It can stabilize the carbon content of molten iron, optimize the microstructure of castings, improve the tensile strength and toughness of castings, and effectively reduce casting defects such as shrinkage cavities and porosity.

Steelmaking Industry: Used for carbon element supplementation in medium-frequency furnaces and converters, precisely controlling the carbon content of molten steel, stabilizing furnace temperature, reducing smelting power consumption, and suitable for the production conditions of low-sulfur high-quality carbon steel and alloy steel.

Carbon Material Manufacturing: As a raw material for the production of carbon electrodes, carbon bricks, and high-temperature furnace refractory linings, it improves the conductivity and high-temperature corrosion resistance of carbon products, and extends the service life of industrial kiln refractory materials.

Other Industrial Scenarios: Auxiliary additives in silicon carbide production, high-temperature resistant auxiliary materials in the metallurgical industry, conductive fillers for industrial antistatic products, etc.
