REFRACTORY CASTABLE - 80% ALUMINA - 55 LBS
This refractory castable with a low cement content (lime) has excellent mechanical properties such as abrasion resistance and low porosity.
Baking: It is important to bake the refractories slowly to prevent them from cracking or bursting. After curing for 24 hours (drying of the fresh concrete), the refractory can be baked gradually at a rate of 25°C/h, stopping at 150°C and 315°C for stages of a few hours (1h/inch of material).
Density: 175 lbs / ft3.
