Abrasion Resistant Refractory High Alumina Castable For Cement
Description
Abrasion-resistant refractory high alumina castable is a type of
refractory material used in high-temperature applications where
resistance to abrasion is required. It is typically composed of
high alumina aggregates, binders, and additives, which are mixed
with water to form a workable slurry.
The high alumina content in the castable gives it excellent thermal
stability and resistance to high temperatures, making it ideal for
use in furnace linings, kilns, and other high-temperature
applications. The addition of abrasion-resistant additives further
enhances the material's durability and resistance to wear and tear.
Abrasion-resistant refractory high alumina castable is applied by
pouring or gunning into place and then allowed to dry and cure.
Once cured, it forms a dense and hard surface that is highly
resistant to abrasion and erosion. Its ability to withstand harsh
environments and extreme temperatures make it a popular choice for
applications in the iron and steel, cement, and power generation
industries.
