Refractory dry-out & curing

Refractory dry-out & curing

Drying refractory is critical for strong, long-lasting refractory applications.

Standard refractory dry-out schedules, provided by all refractory manufacturers with their products,
These standard dry-out schedules are generic and require temperature monitoring rarely found at power plants, where monitoring capabilities are limited. Power plants monitor what is important to maintain the product operations

Dry out, also referred to as bake out, is the process for removing both the mechanical water (added during the mixing process) and chemical water (originally added in manufacturing) from the refractory.

Dry out must not be confused with curing, which is the process of keeping the refractory material wet or the surrounding atmosphere humid for 24 hours prior to applying heat for drying.

This curing process is required on all cement-bonded refractory to create the most favorable conditions to complete the chemical reactions of the cement and water.
