High-Strength Alkali-Resistant Castable
High-strength alkali-resistant refractory castable is made from aluminum silicate and high-pressure electric porcelain as refractory aggregates and powders, formulated with aluminate cement and additives. It is a high-quality castable that can effectively resist the erosion of alkali metal oxides at high temperatures. At high temperatures, it reacts with alkali metal oxides to produce a high-viscosity liquid phase, forming a glazed protective layer. It has the characteristics of stable chemical composition, good fluidity, high strength, and strong erosion resistance. It is mainly used in the preheater system of cement kilns.
