DESCRIPTION
High-Strength Low-Cement Castable is a type of castable refractory material that has lower cement content and higher strength compared to traditional refractory castables. This type of castable is made by reducing the amount of cement binder in the mix and replacing it with alumina or other high-purity fillers.
The refractory castables are recommended for use in applications that require high strength and abrasion resistance, as well as thermal shock resistance. They are commonly used in high-temperature furnaces, kilns, boilers, and other industrial applications where temperatures can range from 1200°C to 1800°C.
Benefits include:
– High strength and abrasion resistance
– Excellent thermal shock resistance
– Low porosity and permeability
– Good resistance to chemical attack
– Easy installation and maintenance
