High alumina castable, also known as alumina castable refractory, is a type of unshaped refractory material formulated with high-purity alumina aggregates, calcium aluminate cement, and carefully selected additives. Compared with conventional fireclay castables, high alumina refractory castable offers higher refractoriness, better load-bearing performance, and improved resistance to thermal shock and slag attack. Depending on the alumina content and formulation design, high alumina castable can operate continuously...
