Petroleum coke recarburizer is a core recarburizing material in the steelmaking and casting industries. Made from high-quality delayed petroleum coke through high-temperature calcination, crushing, and screening processes, it boasts high carbon content and low impurities. It is suitable for electric arc furnaces, medium-frequency induction furnaces for steelmaking, and ductile iron and gray cast iron casting applications. The product strictly adheres to the GB/T 30583-2014 standard, with leading industry performance in key indicators: fixed carbon ≥98.5%, sulfur content ≤0.05%, nitrogen content ≤0.08%, ash content ≤0.3%, volatile matter ≤0.8%, moisture content ≤0.5%, and customizable particle size (1-5mm/5-10mm, etc.).
It offers outstanding recarburizing efficiency, dissolving quickly in molten steel/iron with a carbon recovery rate of 90%-95%, allowing for precise control of carbon content to the target range and reducing alloy consumption. Its low sulfur and nitrogen content effectively reduces gas content in molten steel/iron, improving casting density and mechanical properties, and preventing defects such as pores and cracks. The product has good fluidity, ensuring uniform feeding without clumping, with a consumption rate of only 0.8-1.2 kg/t, reducing overall costs by more than 12% compared to ordinary recarburizers. It is a cost-effective choice for steel companies seeking quality improvement and cost reduction, and for the casting industry aiming to improve product yield.
