Graphitized Petroleum Coke (GPC), also known as low nitrogen recarburizer, is a premium high-carbon additive specifically engineered for the steel manufacturing industry. By undergoing a high-temperature graphitization process, this material offers exceptional carbonization efficiency, allowing steel producers to achieve precise carbon content levels rapidly while significantly reducing production cycles.
Designed to meet the rigorous demands of modern metallurgy, our GPC minimizes nitrogen contamination, which is critical for preventing nitrogen brittleness. This ensures that the final steel product maintains superior toughness, plasticity, and structural integrity, making it an essential raw material for high-performance alloy steel production.

Frequently Asked Questions
Q: What are the main benefits of using GPC over traditional recarburizers?
GPC offers superior carbonization speed, significantly lower nitrogen content to prevent steel brittleness, and a more environmentally friendly production process.
Q: At what temperature should GPC be added to molten steel?
For optimal decomposition and functional performance, GPC should typically be added at temperatures between 1500°C and 1800°C.
Q: How is the dosage of low nitrogen recarburizer determined?
Dosage is based on the specific steel grade requirements, but generally, it does not exceed 1% of the total mass of the molten steel.
Q: Does GPC affect the environmental footprint of the steel plant?
Yes, positively. GPC is a green material that reduces harmful gas emissions and wastewater during production and simplifies subsequent treatment.
Q: What packing options are available for international shipping?
We provide 1-ton Jumbo bags, 25kg small bags, and bulk container loading (20-21 tons per container) to meet various customer needs.
Q: How does the particle size of GPC influence steel quality?
Uniform and smaller particle sizes dissolve more easily, which ensures a more homogeneous distribution of carbon throughout the steel melt.
