Repeated heating and cooling can cause cracking, spalling and loss of lining integrity even when peak service temperature is within specification.
Key considerations
- Consider heating rate, cooling rate and temperature gradients, not only peak temperature.
- Select materials with compatible expansion behavior and stable bonding.
- Use controlled dry-out and operating procedures to reduce avoidable thermal stress.
Application-focused decisions
Refractory selection should reflect the actual operating environment, installation method and maintenance objective. Temperature alone is not enough: chemical attack, abrasion, thermal cycling, mechanical impact and available repair time should be evaluated together.
Installation and inspection
Correct storage, mixing, surface preparation, installation and dry-out are essential to achieving the intended performance. Routine inspection data helps maintenance teams identify wear trends, schedule repairs and improve the lining strategy for future campaigns.
