Product Description
Product Name: High Carbon Recarburizer | Graphite Petroleum Coke & Calcined Petroleum Coke Based
Recarburizer, also known as carbon raiser or carburizer, is a high-purity carbon material used to increase the carbon content in molten iron and steel during the smelting process. Our recarburizer is manufactured from high-quality graphite petroleum coke and calcined petroleum coke, ensuring rapid absorption, high carbon recovery rates, and minimal impurity content.
With fixed carbon content ranging from 90% to 98.5% and ultra-low sulfur, nitrogen, and ash levels, our recarburizer is the ideal choice for foundries and steel mills seeking to improve casting quality while reducing production costs.

Major Industrial Applications
Steelmaking (EAF & Ladle Furnace)
Used to adjust carbon content in molten steel during electric arc furnace and ladle furnace refining. Our recarburizer ensures precise carbon control for producing high-quality carbon steel, alloy steel, and stainless steel.
Iron Foundries (Ductile & Gray Iron)
Essential for producing ductile iron and gray iron castings. Proper carbon adjustment improves graphite morphology, enhances mechanical properties, and reduces casting defects.
Brake Pad Manufacturing
High-purity recarburizer is used as a friction material modifier in brake pad production, improving wear resistance and thermal stability.
Carbon Products & Refractories
Serves as a carbon additive in the production of graphite electrodes, carbon blocks, and refractory materials.
Battery Materials
Emerging applications in carbon-based battery material production.
