LOWER TRANSITION ZONE . The lower transition zone is the basic brick area closest to the kiln discharge. Coating conditions are normally unstable. Refractory wear can occur from thermal stress, the infiltration of clinker liquids and alkali salts, and thermal shock from sudden coating loss. BURNING ZONE . The burning zone center features a thick and stable coating.
