Low-Creep Fireclay Brick Al2O3 43%
Low-creep fireclay brick, Al2O3 43%, max 1430°C. Minimal deformation under sustained load — ideal for kiln car decks, furnace arches, and rotary kiln riding rings in cement and lime plants.
// Key Features
- Low creep rate at 1400°C for dimensional stability under sustained load
- High refractoriness under load ≥1370°C for arch and roof applications
- Uniform dense texture minimising stress concentration in arch structures
- Extended campaign life under cyclic thermal loading conditions
