Description of Alkali-resistant Refractory Castable:
Alkali-resistant refractory castable has high strength, strong resistance to corrosion of alkali metal oxides and their compounds in medium and high temperature environments. At the same time, this castable have good chemical stability, impact resistance, erosion resistance, abrasion resistance, and long service life.
