Refractory Castable is manufactured from high-quality refractory aggregates, binders, and additives to ensure reliable performance under extreme thermal and mechanical conditions. Once mixed with water, it can be easily installed by casting, pumping, or vibration, allowing the formation of seamless and complex linings. It offers excellent thermal stability, abrasion resistance, thermal shock resistance, and chemical corrosion resistance. Compared with traditional refractory bricks, refractory castables reduce installation time, minimize joints, and improve overall lining integrity and service life.
