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.
Product Overview
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.
Composition
ORCAST 90 S is manufactured using carefully selected refractory raw materials, including:
- High Purity Alumina Aggregates
- Reactive Alumina
- Calcium Aluminate Cement
- Fine Refractory Fillers
- High-Performance Mineral Additives
- Optimized Particle Size Distribution
This advanced formulation provides superior density, excellent workability, and long-term durability.
