Recarburizer, also known as a carbon additive, is a material used to increase the carbon content in molten metals, primarily in iron and steel production. During melting processes, carbon content often decreases due to oxidation and other chemical reactions. Recarburizers are added to compensate for this loss, ensuring the final product meets the desired carbon specifications.
Common types of recarburizers include graphite (natural or synthetic), calcined petroleum coke (CPC), and anthracite coal. The selection depends on factors such as purity, carbon content, sulfur level, and application requirements. High-quality recarburizers have a high fixed carbon content (typically above 95%), low sulfur, and good solubility in molten metal, which ensures efficient carbon absorption and minimal impurities.
In foundries, recarburizer is particularly important for producing cast iron, where precise carbon levels influence the mechanical properties, hardness, and machinability of the final casting. In steelmaking, it helps control the carbon percentage for specific grades and processes, including electric arc furnace (EAF) operations.
Proper use of recarburizer not only improves product quality but also reduces costs by allowing the use of lower-grade raw materials and adjusting carbon levels more precisely. It is an essential material for maintaining chemical balance and enhancing the performance of metallurgical processes.
