Gunning mixes for tundish lining
Gunning mixes for tundish lining are composed of refractory aggregates and powders, binding agents, and admixtures. The refractory aggregates and powders provide the main mechanical strength and refractoriness of the material, while the binding agent holds these particles together to form a cohesive mass. Admixtures may be added to improve specific properties such as workability, setting time, or resistance to erosion and corrosion.
Gunning mixes for tundish lining application:
Gunning mixes for tundish lining are primarily used to repair and maintain tundish linings in steel production processes. They are applied using a gunning machine, which projects the mix onto the lining surface at high speed. This method allows for rapid repair and restoration of the lining, minimizing downtime and improving production efficiency.



Properties and advantages of tundish lining application:
High Refractoriness: Gunning mixes for tundish lining have high refractoriness, which makes them capable of withstanding the high temperatures encountered in steel production processes.
Good Resistance to Erosion and Corrosion: These mixes are formulated to resist erosion and corrosion from molten steel and slag, ensuring the longevity of the tundish lining.
Rapid Setting Time: Gunning mixes have a relatively short setting time, allowing for rapid hardening and strength development after application.
Ease of Application: The gunning method allows for easy and rapid application of the mix, reducing labor intensity and improving work efficiency.
Gunning mixes for tundish lining are essential refractory materials in the steel production industry. Their composition, classification, application, properties, and advantages make them ideal for repairing and maintaining tundish linings, ensuring the smooth operation of steel production processes.
