What is High Alumina Castable Refractory Materials?
Basically, the high alumina castable refractory consists of monolithic refractory materials. Basically, they are made of high alumina aggregate and powder, mixed with a binder and water reducer.
Moreover, the Aluminum Oxide or Al₂O₃ content in this refractory material is over 48%.
Application of High Alumina Castable
Generally, it is a popularly used material in refractory for its mechanical strength, resistance to heat, shock, and abrasion.
Because of its superior performance, high alumina refractory materials are commonly used in many industries such as steel, petroleum, chemical, and power generation.
Additionally, it is the ideal refractory material for lining furnaces and kilns including boilers, ceramic kiln, blast furnaces, and chimneys.

What is High Alumina Castable Material?
Basically, high alumina refractory products are a type of refractory castable composition. It has other compositions such as alumina powder, bauxite powder, high alumina castable cement, and silica fume.
Subsequently, they are mixed following the set proportions which suit the construction or repair work application.
Moreover, what makes it very high quality is the less amount of cement. Therefore, it can withstand extreme temperatures which benefits many industrial plants.
Because it is produced into powder and aggregate, it is the ideal refractory product to use the high alumina castable material for harsh conditions.
High Alumina Refractory Castable Cement Benefits
Other than the benefits stated above, this refractory lining material has many other advantages which makes it ideal for most applications.
