Our Graphitized Petroleum Coke, also known as Low Nitrogen Recarburiser, is a premium-grade carbon additive engineered for high-precision steel manufacturing. Designed to optimize the recarburization process, this material ensures a rapid and efficient increase in carbon content, significantly reducing production cycles while maintaining the highest structural integrity of the liquid steel.
By leveraging advanced graphitization technology, our recarburiser eliminates the risks associated with high nitrogen levels, effectively preventing nitrogen brittleness. This results in steel products with superior toughness, enhanced plasticity, and a highly uniform carbon distribution, making it the ideal choice for manufacturers striving for international quality standards in ferroalloy smelting.
