Graphitized Petroleum Coke, also known as Low Nitrogen Recarburiser, is a high-performance carbon additive engineered specifically for the steel manufacturing industry. Designed to optimize the recarburization process in BOF and EAF furnaces, this material ensures a rapid and precise increase in carbon content, significantly shortening production cycles while maintaining the highest standards of metallurgical purity.
By prioritizing low nitrogen levels and a uniform particle size distribution, our recarburiser eliminates the risks of nitrogen brittleness, enhancing the overall toughness, plasticity, and mechanical properties of the final steel products. It represents a sustainable, eco-friendly solution for modern foundries seeking to balance industrial efficiency with stringent environmental regulations.

| Feature Comparison | Traditional Recarburiser | Our Low Nitrogen Recarburiser |
|---|---|---|
| Production Cycle | Longer duration | Shortened (Fast carbonization) |
| Nitrogen Content | Higher (Risk of brittleness) | Ultra-Low (≤ 300 PPM) |
| Steel Toughness | Standard/Variable | Significantly Enhanced |
| Environmental Impact | Higher emissions | Eco-friendly/Green material |
| Carbon Uniformity | Lower (Slow dissolution) | High (Uniform particle size) |
By reducing the nitrogen content in liquid steel, it prevents nitrogen brittleness, which directly increases the toughness and plasticity of the finished steel products.
To ensure the material is completely melted and functions optimally, it should be added to the BOF at temperatures between 1500°C and 1800°C.
While dosage depends on specific product requirements, it is generally recommended that the amount added does not exceed 1% of the total liquid steel volume.
Uniform particle size allows the recarburiser to dissolve more easily and quickly, improving the dispersion and homogeneity of carbon throughout the steel liquid.
Yes, it is a green material that produces no harmful gases, wastewater, or residue during production and reduces the environmental burden of subsequent steel treatments.
Our products are strategically delivered via Xingang Port or Qingdao Port in China to ensure efficient global shipping.
