Product Description:
Calcined bauxite is a widely used material in various industrial applications, including the production of refractory bricks, abrasives, and welding electrodes. Calcined bauxite is produced by calcination of bauxite ore at 900 to 1700 °C by a rotary kiln or multiple hearth furnace kiln
Key Properties:
- High Hardness and Durability: Calcined bauxite has a high hardness rating, making it an extremely durable material
- Chemical Stability: Calcined bauxite is a chemically stable material that is resistant to corrosion and erosion
- Heat Resistance: Calcined bauxite has a high melting point, making it an ideal material for use in high-temperature applications. It can withstand temperatures of up to 1770°C
- Alumina Content: This content usually ranges from 70% to 90% or above depending on the grade acquired
Applications:
- aluminum production, abrasives, cement, ceramics & flooring
- production of alumina refractories containing 75 to 90% of alumina; these are used in the manufacture of bricks to lane the roof of blast furnaces and electrical and steel-making furnaces
- anti-skid applications, vehicle skid prevention and on surfaces requiring additional safety
- Essential in refractory bricks, castables, and furnace linings, grinding wheels, sandpapers, and polishing compounds
