TRLCAST AH-90 (K) is a premium-grade High Alumina Refractory Castable developed by TRL Krosaki Refractories Limited for high-temperature industrial applications where exceptional thermal stability, mechanical strength, abrasion resistance, and long service life are essential. Manufactured using carefully selected high-purity alumina aggregates, calcium aluminate cement, and specially engineered additives, this refractory castable is designed to withstand extremely harsh operating conditions while maintaining structural integrity and excellent performance.
Modern industries such as steel manufacturing, cement production, power generation, foundries, petrochemical processing, and waste incineration require refractory materials capable of resisting continuous exposure to extreme temperatures, thermal cycling, molten materials, and mechanical wear. TRLCAST AH-90 (K) has been developed to meet these demanding requirements by providing a dense, durable, and highly refractory lining that enhances equipment reliability, improves thermal efficiency, and reduces maintenance downtime.
Product Overview
TRLCAST AH-90 (K) is supplied as a ready-to-use dry refractory castable that only requires the addition of clean water before installation. Once mixed, the material produces a homogeneous refractory concrete that can be cast, vibrated, or poured into the required lining structure.
After proper curing and controlled heat-up, the castable develops excellent mechanical strength and forms a dense refractory lining capable of resisting severe thermal, chemical, and mechanical stresses.
The product is particularly suitable for installations where high alumina content and superior resistance to abrasion and thermal shock are required.
Composition
TRLCAST AH-90 (K) is formulated using premium refractory raw materials, including:
- High Purity Alumina Aggregates
- Reactive Alumina
- Calcium Aluminate Cement
- Special Mineral Fillers
- Performance-Enhancing Additives
- Carefully Controlled Particle Size Distribution
This optimized formulation ensures excellent flowability, workability, density, and long-term performance.
