EXPRESS 27 55# Bag High Strength Conventional Castable
Dense, Self-Flowing Refractory Castable
Features: High density and very good abrasion resistance properties are ideal for hot face lining material.
Can also be vibration cast using reduced water levels, providing properties superior to those attained at self-flowing consistency.
Uses: Fluid Catalytic Cracking Unit (FCCU) transfer lines, cyclones, air heaters, and boilers.
Rotary kiln linings and lifter shapes.
Furnace door jambs and lintels.
Annealing furnace cartops.
Aluminum holding furnace upper sidewall and roof regions.
Silica (SiO2) 42.2%
