88% high alumina calcined bauxite price
introduce
Calcined bauxite is one of the main ores of aluminum. Calcined bauxite contains hydrous aluminum
oxides and aluminum hydroxides, through tropical and
subtropical regions. Calcined bauxite is obtained by calcining (heating) high-quality bauxite at high temperature
Temperature (from 85OC to 1600C). This removes moisture which increases the alumina content.
Calcined bauxite has alumina content compared to the approximately 57% to 58% alumina content of primary bauxite
The content is 84% to 88%. Heating takes place in a rotary kiln.
application
1. Aluminum metallurgy
2. Precision casting/investment casting:
Bauxite clinker fine powder can be made into precision casting molds.
3. Refractoriness: The refractoriness of high alumina bauxite can reach 1780°C.
Has good chemical stability and mechanical properties. (Al2O3 ≥48% low Fe2O3)
4. Aluminum silicate refractory fiber: high alumina bauxite clinker can be melted at 2000°C-2200°C in an electric arc furnace, and becomes aluminum silicate refractory fiber after a series of processing.
It can be made into fiber blanket, board and cloth.
5. Mix magnesia and bauxite clinker with binder to cast ladle for better overall lining
Performance.
6. Production of bauxite cement
7. Abrasives
8. Ceramic industry
9. Chemical industry of various aluminum compounds.
