Refractories that will optimize your upper transition zone

When liquid phase begins to appear in the raw meal, the kiln lining becomes more vulnerable. This occurs in the upper transition zone.
The more variables that occur, the greater the need for the correct magnesia-based refractories. Variables include:
- Variations in oxygen potential, caused by use of multiple fuels. After several redox cycles, some brick qualities may become weak and friable.
- Operation with an unstable coating – caused by a variety of factors. Brick becomes exposed to infiltration by clinker liquid phase.
- Direct action of alkali chlorides and sulfates, a result of using several waste fuels. Brick may subsequently cap.
- Build-up of abnormal rings, resulting from unbalanced sulfate modulus.
- Kiln shell corrosion, caused by sulfate and chloride diffusion through the refractory, can result from the burning of some waste fuels.
