Reducing Energy Costs and CO₂ Emissions in Steelmaking Through Optimized Tundish Refractories
Rising energy prices and strict environmental regulations have made energy efficiency and CO₂ reduction critical priorities in the steel industry. The tundish, as one of the most frequently relined units, plays a key role in controlling both energy consumption and operational costs.
Why the Tundish Matters for Cost Reduction
Due to frequent relining cycles and the need for drying and preheating, tundishes consume significant amounts of energy. Optimizing this process can result in substantial cost savings.
The Role of Refractory Materials
Refractory materials used in tundish linings directly influence energy consumption. Advanced technologies such as:
- Sol-bonded permanent linings
- Cold-setting wear linings
significantly reduce natural gas usage.
Economic Impact of Gas and CO₂
Each cubic metre of natural gas produces approximately 2 kg of CO₂. Therefore, reducing gas consumption lowers both fuel costs and carbon-related expenses.
- Up to 70% gas reduction in permanent lining
- Over 40% reduction in wear lining
- Significant cost savings per tonne of refractory
Improving Productivity
Advanced refractory systems reduce drying time and increase tundish availability, leading to:
- Reduced downtime
- Higher production capacity
- Improved operational efficiency
Strategic Importance of Refractory Selection
Modern steel plants evaluate refractories based on total cost of ownership (TCO), energy consumption, and environmental impact rather than initial cost alone.
