About REFRACTORY CASTABLES
REFRACTORY CASTABLES mixture is a highly proportionate premixed substance that is commonly used within industries to make thermal resistant bricks and various types of refractory products. It is prepared by using highly pure substances that are obtained from earths crust and rocks. It is available in powdered form with zero solid impurities that ensure excellent mix-ability. REFRACTORY CASTABLES offered by our company can also be used to make protective layers with furnaces. The offered powdered compound comes in water resistant bags with capacity of 25 kilograms.

Exceptional Thermal Performance and Strength
With a melting point of 1790C and a service temperature up to 1800C, these refractory castables are built to endure extreme thermal stresses. Their high compressive strength (over 70 MPa) and excellent flexural strength provide robust structural reliability, making them suitable for critical high-temperature areas such as cement kilns, steel furnaces, and petrochemical applications.
Versatile Installation Methods for Various Industrial Needs
These castables can be installed using vibration casting, gunning, or pump casting, allowing flexibility to suit diverse project requirements. The setting time ranges from 30 to 60 minutes, enabling efficient application in fast-paced installations, whether for large furnaces, boilers, or custom-shaped burner blocks.
Outstanding Durability and Storage
Designed with a shelf life of 612 months when properly stored in a cool, dry place, our refractory castables maintain their performance and handling characteristics over time. Composed of high-purity materials (Al2O3 up to 90%), they retain strength, low water absorption, and low-to-medium porosity for extensive operational longevity.
FAQs of REFRACTORY CASTABLES:
Q: How do you install refractory castables for industrial applications?
A: These refractory castables are typically installed using vibration casting, gunning, or pump casting methods. Proper mixing with water, careful placement, and adherence to the recommended setting time (3060 minutes) are essential for achieving optimal performance in furnace linings, boilers, or kilns.Q: What are the main benefits of using high-purity refractory castables?
A: High-purity refractory castables (up to 99% purity) ensure superior resistance to thermal shock, low water absorption, and minimal porosity. This translates to extended service life, lower maintenance, and enhanced energy efficiency in high-temperature applications like steel plants and cement rotary kilns.Q: When should refractory castables be replaced in heavy-duty furnaces?
A: Replacement is generally necessary when there are visible cracks, signs of erosion, or a loss in mechanical strength. Regular inspections should be conducted, especially after long operational cycles or thermal shocks, to identify any deterioration before it impacts furnace performance.Q: Where can these refractory castables be effectively used?
A: These products are ideal for use in steel plants, cement industries, petrochemical furnaces, foundries, and industrial boilers. Their versatility and high strength make them suitable for lining cement rotary kilns, burner blocks, and various industrial heating zones.Q: What storage conditions are recommended to maintain product shelf life?
A: To preserve the quality and shelf life (612 months), store refractory castables in a cool and dry place. They should be kept in their original 25 kg or 50 kg packaging and protected from moisture to prevent hydraulic setting or contamination.Q: How does grain size impact the performance of refractory castables?
A: Grain size (up to 6 mm) affects the mechanical strength and insulation properties of the castables. Larger grains typically increase mechanical strength, while finer grains can enhance surface smoothness and reduce porosity, catering to specific application requirements.
