Castable Refractories
Versatile monolithic refractory materials for rapid installation and superior thermal performance
Monolithic Refractory Solutions
Castable refractories are hydraulically-bonded materials that can be poured, pumped, or gunned into place, offering exceptional flexibility in furnace design and rapid installation compared to traditional brick linings. They develop strength through chemical bonding and sintering.
Our castable refractories range from conventional cement-bonded formulations to advanced low-cement and no-cement castables, providing superior performance, reduced porosity, and enhanced thermal shock resistance for demanding high-temperature applications.
