Silicon Carbide Deoxidizer for Steelmaking
FerrumX silicon carbide deoxidizers cover the full purity range — from 40% cost-grade to 99% ultra-pure — for deoxidation, carburization, and silicon enrichment across every steelmaking route.
FerrumX places particular emphasis on three characteristics of silicon carbide that drive steelmaking performance: deoxidation, carburization, and silicon enrichment — with tight control over the final chemical composition.

Ladle Furnace (LF) refining
Supports precise composition control via rapid white-slag formation.
VD / VOD vacuum refining
Holds a clean reducing atmosphere for low-oxygen, high-purity steel.
Blast-furnace taphole clay
Core refractory aggregate raising slag-erosion and thermal-shock resistance.
FAQ
Silicon Carbide for Steelmaking — FAQ
It reacts with dissolved oxygen in the molten bath to form SiO₂ and CO, driving oxygen into the slag while adding silicon and carbon; the exothermic reaction also raises bath temperature.
Match SiC content to steel quality and refining level: 40% for routine casting, 60–80% for standard and alloy steel, 90% for clean steel, and 97–99% for bearing, pipeline, and aerospace steels.
Commonly 3–6 kg per ton of steel, split between ladle-bottom pre-deoxidation and stream addition during tapping; tune to grade and furnace.
Higher-grade SiC (80% and above) can fully replace ferrosilicon and high-carbon manganese, with more stable chemistry and lower cost.
Yes. The deoxidation reaction is exothermic; 8 kg per ton typically adds ~48 °C and cuts EAF power by 10–40 kWh/t.
SGS, BV, and CCIC inspection are acceptable on request across the range.
