Refractories that will optimize your lower transition zone
Though less complex than the burning zone, the variables that affect the lower transition zone are still extensive.
Excessive ovality of, or damage to, the kiln shell causes mechanical stress. This can lead to crushing and displacement of refractories and, ulitmately, may cause a catastrophic twisting of the brick lining.
Use of alternative fuels with high alkaline and sulfur content may lead to "capping", caused by the infiltration and condensation of alkalis in the brick. This phenomenon can also occur as a result of thermal overload, or from firing with the burner tip coincident with the nose ring or outlet zone. Thermal overload can also cause spalling, a result of thermal shock.
Very abrasive "dusty" clinkers - high in SiO2 - can cause high abrasion wear on refractories.
