Calcined Bauxite Specifications
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.
Usage
1) The bauxite for aluminum industry in defense, aerospace, automotive, electrical, chemical, and daily supplies;
2) Bauxite clinker processed into fine powder and made after the casting mold. Used in military, aerospace, communications, instrumentation, machinery and medical equipment sector;
3) The bauxite can be used in refractory products. The refractoriness of high-alumina clinker is up to 1780 . Its features are chemical stability strong, and physical properties of sound;
4) It can manufact alumina cement, abrasive materials and aluminum compounds.
