1. What Are Refractory Castable Material?
Refractory castable material are heat-resistant concrete superheroes—versatile, unshaped materials that harden into monolithic linings when mixed with water. Composed of aggregates (bauxite, corundum), binders (calcium aluminate), and additives, they thrive in temperatures up to 1,800°C (3,272°F). Kerui’s castables are engineered for:
- Rapid Installation: Build complex shapes in hours, not days.
- Seamless Defense: Eliminate weak joints vulnerable to heat/slag attacks.
- Adaptability: Perfect for repairs, linings, and custom geometries.
