A practical guide to service temperature, slag chemistry, thermal cycling and repair strategy when selecting converter refractory materials.
Key considerations
- Match the repair material to the damaged zone and its dominant wear mechanism.
- Evaluate slag attack, steel erosion, thermal shock and installation time together.
- Use inspection records to improve material selection over successive campaigns.
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.
