Products Description
Recarburant, also known as Carbon Raiser, Recarburizer, or Graphite Petroleum Coke (GPC), is an essential carbon additive used in steelmaking, foundry casting, and other metallurgical industries. It is mainly produced from high-quality petroleum coke through graphitization at high temperature. GPC features high fixed carbon content, low sulfur, and excellent absorption rate, making it a preferred choice for improving molten iron and steel quality.

Characters of GPC Recarburant
High Fixed Carbon Content – ensures efficient carburization.
Low Sulfur and Nitrogen – minimizes harmful impurities in steelmaking.
High Absorption Rate – up to 95% in induction and electric furnaces.
Good Graphitization Structure – excellent conductivity and stability.
Customizable Particle Size – meets different furnace requirements.
How Does Recarburizer Improve Carbon Recovery?
In steelmaking and casting, carbon tends to be lost during smelting due to oxidation. Recarburizer (GPC) is added to molten iron to supplement carbon content. Thanks to its graphitized structure and low impurities, GPC dissolves quickly and absorbs efficiently into molten metal. This results in:
Improved carbon recovery rate (up to 90–95%)
Reduced overall alloy consumption
Stable and controllable carbon levels
Enhanced mechanical properties of steel and cast iron
Is There an International Certification for Carbon Raiser?
Yes. Recarburizer (GPC) is widely certified and tested according to international quality standards. Many manufacturers comply with:
ISO 9001:2015 – Quality Management System
SGS / BV Inspection Reports – Third-party testing for carbon, sulfur, and trace elements
RoHS / REACH Compliance – For environmental and safety standards in international trade
These certifications ensure that GPC meets the global requirements for steelmaking and casting industries.
