High-Alumina Whytheat Castables are high-performance refractory monolithic materials designed for lining furnaces, boilers, kilns, and other high-temperature industrial equipment. These dense castables are manufactured using high-purity alumina aggregates, calcium aluminate cement binders, and selected additives, providing excellent mechanical strength and thermal stability.
Whytheat castables are widely used in industries such as steel, cement, petrochemical, power generation, and foundries, where reliable refractory performance under extreme heat conditions is essential.
