Sintered Calcium Aluminate High Al2O3
Description
escription:
Calcium Aluminate for Metallurgy is a kind of auxiliary material for steelmaking, as it speeds up secondary metallurgy process, especially faster desulphurization, Improves overall steel cleanliness and makes high grade steel with cheaper cost.
Specification:
Fused Calcium aluminate:

Tundish Flux: 0-2mm, 3-8mm
Ladle Refining Slag: 5-30mm, 5-50mm
Packing: 1 MT big bag or as per customer’s requirement
Calcium aluminate advantages:
1) Uniform chemical compositions, low melting point, high melting speed, and short smelting time;
2) It has no fluoride and doesn’t erode furnace lining and ladle, and it is compact, non-absorbent, and easy to storage as well;
3) Stable phase and fast dust-reducing speed, rapid desulfurization effect stabilized at 60%, and suppresses phosphorus into molten steel;
4) Improving the protective effect and reducing erosion to ladle lining.
Remark: specification and size can be optimized by per customer’ requirement
