Premium-grade carbonizer with fixed carbon content of 98.5%+ and ultra-low ash content below 0.5%, engineered for precise carbon adjustment in steelmaking and casting processes. Ensures rapid carbon dissolution and uniform distribution in molten steel.
Carbonizers are indispensable additives in modern steelmaking, serving as the primary means of adjusting carbon content in molten steel to meet precise grade specifications. Our premium carbonizer is produced from carefully selected petroleum coke and graphite sources, processed through high-temperature calcination to achieve fixed carbon levels exceeding 98.5% with ash content consistently below 0.5%. This exceptional purity translates to a carbon absorption rate of 92–95% in typical ladle furnace conditions, significantly reducing material waste and ensuring predictable carburization outcomes.
In electric arc furnace (EAF) operations, carbonizer is typically added during the meltdown and refining phases to compensate for carbon oxidation losses. The material’s rapid dissolution kinetics—achieved through controlled particle sizing between 1–5 mm—allow metallurgists to make fine adjustments to carbon content within tight tolerance bands, typically within +/- 0.02% of the target specification. For foundries producing ductile iron, consistent carbon recovery is critical for achieving the required carbon equivalent (CE) values that govern nodular graphite formation and mechanical properties in the final casting.
Quality-conscious steel mills demand carbonizers with sulfur content below 0.05%, as excessive sulfur can lead to hot shortness in finished steel and necessitate additional desulfurization treatments. Our product undergoes rigorous quality control at every production stage, including X-ray fluorescence (XRF) analysis and fixed carbon determination using the combustion method, ensuring each batch meets the stated specifications. The material is packaged in moisture-proof bags to prevent humidity absorption during storage and transport, preserving its performance characteristics from warehouse to furnace.
