Product Description of Affordable Factory Price High Alumina Refractory Bricks Refractory Castable Raw Material Refractory Calcined Bauxite
Calcined Bauxite is manufactured by subjecting high-alumina bauxite to high-temperature sintering in rotary, shaft, or round kilns. This process drives off the moisture, concentrating the alumina content and significantly improving the material's refractoriness. Additionally, the calcination process reduces iron levels, resulting in a product with superior hardness and toughness. Due to its excellent thermal stability, resistance to molten slags, and remarkable mechanical strength, Calcined Bauxite is highly sought after in industries that produce refractory materials, abrasives, and other specialized products designed for high-temperature environments.
