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.  Precast shapes.  Furnace door jambs and lintels.  Annealing furnace cartops.  Aluminum holding furnace upper sidewall and roof regions.
