Graphitized Petroleum Coke (GPC), also known as a low-nitrogen recarburizer, is a high-performance carbon additive engineered specifically for the modern steel manufacturing industry. By utilizing a sophisticated high-temperature reduction process, GPC provides an efficient solution for precise carbon adjustment in molten steel, ensuring superior metallurgical properties and structural integrity of the final product.
Designed to meet the stringent demands of high-quality steel production, our GPC minimizes impurities and optimizes the carbonization process. It serves as a critical raw material for manufacturers seeking to enhance the toughness, plasticity, and overall quality of their steel while simultaneously reducing production cycles and environmental impact.

Frequently Asked Questions
Q: How does GPC differ from standard petroleum coke in steelmaking?
Graphitized Petroleum Coke undergoes a high-temperature graphitization process, resulting in much higher fixed carbon, lower nitrogen, and lower sulfur compared to standard coke, which prevents steel brittleness.
Q: What is the recommended temperature for adding GPC to molten steel?
For optimal decomposition and functional carbonization, it is recommended to add GPC at temperatures between 1500°C and 1800°C.
Q: Can the particle size of the recarburizer be customized?
Yes, we offer standard sizes including 0-0.2mm, 0.2-1mm, and 1-5mm, but we can also provide customized particle sizes based on your specific furnace requirements.
Q: How does the use of low-nitrogen recarburizers affect steel quality?
By significantly reducing nitrogen content, it eliminates the risk of nitrogen brittleness, thereby improving the overall toughness, plasticity, and durability of the steel.
Q: What is the typical dosage for GPC in the smelting process?
Generally, the amount of GPC added is small relative to the mass of the molten steel, usually not exceeding 1% of the total mass.
Q: Is GPC considered an environmentally sustainable material?
Yes, GPC is a green material. Its production process does not generate harmful gases or wastewater residue, reducing the environmental burden of steel production.
