Precision Carbon Addition for Superior Steel Performance
In modern steelmaking, every element matters-especially carbon. The right carbon raiser doesn't just adjust composition; it enhances final product quality, process efficiency, and cost-effectiveness.
GPC Carbon Raiser is engineered for steelmakers who demand consistency, purity, and performance. From EAF and LF refining to ladle treatment, GPC ensures precise carbon control and improved steel properties.
Why GPC Carbon Raiser?
High Fixed Carbon (≥ 99%) – Maximizes carbon recovery, reduces additive consumption and slag volume.
Ultra-Low Impurities – Sulfur ≤ 0.03%, nitrogen ≤ 0.005%, ash ≤ 0.5%-for cleaner, stronger steel.
Fast Absorption & High Yield – Uniform graphite structure enables rapid dissolution and predictable recovery.
Stable Quality, Batch to Batch – Rigorous production control ensures reliable performance in every heat.
Key Applications in Steelmaking
Electric Arc Furnace (EAF) Steelmaking – Efficient carbon adjustment during melting.
Ladle Furnace (LF) Refining – Precise final carbon trimming before casting.
Special & Alloy Steel Production – Suitable for high-grade, low-sulfur, and nitrogen-sensitive steels.
Continuous Casting Preparation – Helps maintain ideal carbon levels for smooth casting operations.
