Graphitized Petroleum Coke (GPC) is a high-performance, low-nitrogen recarburizer specifically engineered for the modern steel manufacturing industry. By utilizing a high-temperature reduction process, GPC provides an exceptional carbonization capacity that allows steel producers to reach precise carbon specifications more rapidly, significantly optimizing the production cycle and increasing overall furnace efficiency.
Designed to meet stringent metallurgical standards, our GPC minimizes the risk of nitrogen brittleness, thereby enhancing the toughness and plasticity of the final steel product. As an environmentally friendly green material, it eliminates the emission of harmful gases and wastewater residues during production, offering a sustainable solution for high-temperature metallurgical processes between 1500°C and 1800°C.

Frequently Asked Questions
Q: What are the primary benefits of using GPC over traditional recarburizers?
GPC offers significantly lower nitrogen content (≤300PPM), which prevents nitrogen brittleness in steel, enhances plasticity, and reduces the overall production cycle due to its superior carbonization capacity.
Q: At what temperature should Graphitized Petroleum Coke be added to molten steel?
For optimal breakdown and functionality, GPC is typically added at high temperatures ranging between 1500°C and 1800°C.
Q: How does GPC impact the environmental footprint of steel production?
GPC is an environmentally friendly green material. Its production process generates no harmful gases or wastewater residues, reducing the environmental burden of subsequent waste treatments.
Q: What is the recommended dosage for GPC in steel manufacturing?
The dosage is generally small, typically not exceeding 1% of the total mass of the molten steel, depending on the specific product requirements and carbon targets.
Q: Can I request custom particle sizes for my specific furnace setup?
Yes, while we offer standard sizes (0-0.2mm, 0.2-1mm, 1-5mm), we can provide customized particle sizes according to your specific industrial requirements.
Q: How is GPC typically added to the smelting process?
GPC is not added directly to the blast furnace for refining. Instead, it is added to the molten steel in the cooling well or insulation tank and evenly mixed via stirring or standing methods.
