Fused Calcium Alumina is a key synthetic slag material widely used in steel refining, desulfurization, continuous casting, and metallurgical processes. With its fast slag-forming ability and stable chemical composition, it helps improve steel cleanliness, reduce inclusions, and enhance production efficiency.
Our Fused Calcium Alumina is manufactured through high-temperature fusion, rapid cooling, crushing, and sizing to ensure consistent quality and excellent refining performance.
Product Chemistry
Al₂O₃: 35–40%
CaO: 45–50%
SiO₂: ≤ 5%
MgO: ≤ 4%
Fe₂O₃: ≤ 2%
This balanced CaO–Al₂O₃ ratio provides strong desulfurization capability and outstanding fluidity during steel refining.
Available Grain Sizes
5–25 mm
