Calcined Bauxite Applications:
1. Aluminium metallurgy
2. Precision casting / Investment casting:
bauxite grog fines can be made into mold for precision casting.
3. Refractory: high alumina bauxite's refractoriness can reach 1780°C.
It is charactered by good chemical stability and mechanical performance. (Al2O3 ≥48% with low Fe2O3)
4. Aluminium silicate refractory fiber: The high alumina bauxite grog can melt under 2000°C-2200°c in the electric arc furnace.After a series of processing, it can become aluminium silicate refractory
fiber, which can be made into fiber blanket, plate,cloth.
5. Mixing magnesia and bauxite grog with binders to pour the molten steel ladle for better overall lining performance.
6. Producing bauxite cement
7. Abrasives
8. Ceramics industry
9. Chemistry industry for all kinds of aluminium compound.
