Calcined Bauxite
Calcined bauxite is produced by sintering high-grade raw bauxite in rotary kilns, round kilns, or shaft kilns at temperatures of approximately 1600°C–1800°C. Featuring high mechanical strength, excellent thermal stability, and strong slag resistance, it is widely used in the production of shaped and unshaped refractory materials for steel plants, foundries, glass furnaces, and cement industries.
