Product Description of Rongsheng Refractory Supply Refractory Raw Material Aluminum Bauxite Powder Good Price Calcined Bauxite
The production of Calcined Bauxite involves sintering high-quality bauxite in rotary, round, or shaft kilns at elevated temperatures. This heating process removes the moisture present in the bauxite, which increases its alumina concentration and refractoriness. The result is a product with low iron content, enhanced hardness, and exceptional toughness. Thanks to its high thermal stability and resistance to molten slags, Calcined Bauxite plays a crucial role as a raw material in the production of high-performance refractory materials, abrasives, and various specialty applications that require superior strength and durability.
