- Superior Abrasion Resistance: Withstands the scouring effect of solid particles and gas flows, extending service life in high-wear areas.
- Excellent Thermal Shock Stability: Maintains integrity under rapid temperature cycling, preventing cracking and spalling.
- High-Temperature Structural Strength: Retains sufficient cold crushing strength (CCS) and modulus of rupture (MOR) after exposure to operational temperatures.
- Good Corrosion Resistance: Offers reliable performance against certain chemical attacks in industrial atmospheres.
- Proven Application Flexibility: Specifically engineered for critical use in steelmaking, power generation, and waste incineration industries.
This castable is the material of choice for constructing and repairing linings in:
- Power Generation: Circulating Fluidized Bed (CFB) boilers, chain-grate boilers, and other combustion units.
- Steel Industry: Various furnace back-up linings, ductwork, and secondary metal processing units.
- Waste Incineration: Linings for municipal and industrial incinerators.
- General Industry: A wide range of other industrial furnaces requiring a robust, cast-in-place refractory.
The TSCD/LDSCD formulation represents a balance of performance and practicality. Its consistent quality ensures predictable installation and reliable in-service behavior, providing a cost-effective monolithic solution that reduces downtime and maintenance frequency in some of industry’s most punishing thermal environments.
