Tundish Wear Lining Methods and the Advantages of Cold-Setting Mixes

Wear lining in a tundish is a critical consumable layer in continuous casting. It is directly exposed to molten steel, slag, and thermal stresses, and must be replaced after each casting cycle.

The selection of the appropriate wear lining method significantly impacts energy consumption, preparation time, and operational costs.

Main Wear Lining Methods

1. Slurry Gunning

This method involves spraying a wet refractory mix containing 20–35% water onto the tundish walls using compressed air.

• Flexible thickness control
• Widely used in industry
• Requires drying before casting

2. Dry-Setting Mixes

Dry mixes are placed between a form and the permanent lining and activated at elevated temperatures.

3. Cold-Setting Mixes

Cold-setting mixes harden through a chemical reaction at ambient temperature with minimal water addition.

Advantages of Cold-Setting Mixes

• No drying required
• Significant reduction in gas consumption
• Lower CO₂ emissions
• Faster tundish turnaround
• Improved operational efficiency

Performance Comparison

Industrial data indicates that cold-setting mixes can reduce gas consumption by more than 40%, while also shortening preparation time.

Why Choose Cold-Setting Technology?

With increasing energy costs and environmental regulations, cold-setting technology provides a highly efficient and sustainable solution for tundish lining.
