Our castable grades are developed for high temperature furnace areas that require better integrity, anti-peeling behavior, and longer maintenance cycles.
PK INDUSTRIES castable is suited for high temperature and wear-sensitive furnace regions. It supports monolithic lining construction and improved structural integrity.
Compared with conventional refractory brick assemblies, castable can improve lining continuity, reduce joint-related failures, and lower heat loss in selected applications.
