ORCAST 90 S is a premium-quality High Alumina Refractory Castable specially engineered for demanding high-temperature industrial applications where exceptional thermal stability, mechanical strength, abrasion resistance, and long service life are essential. Manufactured using high-purity alumina aggregates, calcium aluminate cement, ultra-fine refractory fillers, and advanced performance-enhancing additives, ORCAST 90 S delivers outstanding performance in severe thermal and mechanical environments.
With an Al₂O₃ content of approximately 90%, ORCAST 90 S provides excellent refractoriness, superior resistance to thermal shock, outstanding structural stability, and excellent resistance against abrasion and slag attack. It is widely used for the installation and repair of refractory linings in steel plants, cement industries, power plants, foundries, petrochemical facilities, and other industries where continuous exposure to extremely high temperatures is common.
Unlike conventional refractory castables, ORCAST 90 S develops a dense and durable refractory structure after proper curing and heat-up. This significantly improves furnace efficiency, extends lining life, minimizes maintenance costs, and reduces unplanned shutdowns.
ORCAST 90 S is supplied as a ready-to-use dry refractory castable that requires only the addition of the recommended quantity of clean water before installation.
Once mixed, it produces a smooth and highly workable refractory concrete suitable for casting, pouring, or vibration installation methods. After proper curing and controlled drying, the material develops exceptional mechanical strength and forms a dense refractory lining capable of withstanding continuous high-temperature service.
Its low porosity and excellent structural integrity make it highly resistant to molten metal splash, slag penetration, thermal cycling, and mechanical wear.
ORCAST 90 S is manufactured using carefully selected refractory raw materials, including:
This advanced formulation provides superior density, excellent workability, and long-term durability.
The approximately 90% Alumina (Al₂O₃) content enables the castable to perform reliably under continuous high-temperature operating conditions.
Develops excellent cold crushing strength and hot strength after proper curing, making it suitable for heavy industrial operations.
Its dense refractory structure effectively resists abrasion caused by clinker, slag, ash, and moving process materials.
Capable of withstanding repeated heating and cooling cycles without cracking or structural damage.
The dense microstructure minimizes slag penetration and enhances refractory lining life.
Maintains dimensional stability during prolonged exposure to elevated temperatures.
Provides durable furnace protection while reducing repair frequency and maintenance costs.
ORCAST 90 S is widely used across numerous high-temperature industries.
Compared with ordinary refractory castables, ORCAST 90 S provides numerous advantages:
These advantages contribute to improved plant productivity and lower operating costs.
Proper installation is essential for achieving maximum performance.
Recommended procedure includes:
Correct installation significantly improves refractory durability.
To preserve product quality:
