sodium silicate high alumina castable
Features and Uses:
Water Glass High alumina refractory castable is made of high alumina bauxite and several other high-quality Materials. It is characterized by high load softening temperature, high strength and good abrasion resistance and so On.
It can be used in hot equipment such as steel rolling industrial furnace, and it needs to be lined with large tensile strength and Anti-thermal shock performance, such as folding angle, furnace arch and other Parts.
