Raw bauxite ore, Al2O3 75% calcined bauxite price
Benefits:
1) Excellent performance thermal shock, spalling and corrosion resistance.
2) Good mechanical strength and high refractoriness.
3) Reduce the residue and porosity of molten steel and good slag resistance.
4) Protect precious metals of the molten steel to reach high efficiency.
5) Labor and cost saving by prolonging campaign length.
Application
1. Aluminium metallurgy
2. Precision casting / Investment casting:
3. Refractory: high alumina bauxite’s refractoriness can reach 1780°C.
4. Mixing magnesia and bauxite grog with binders to pour the molten steel ladle for better overall lining
performance.
5. Producing bauxite cement
6. Chemistry industry for all kinds of aluminium compound.
7. Abrasives
8. Ceramics industry
