| High-temperature zones | 1360°C / 1430°C | 128 kg/m³ | 25–50 mm | Higher heat resistance required |
Typical selection guide for common applications.
Key Selection Factors
- Temperature Requirement
Always choose a grade with a classification temperature higher than your actual operating temperature. - Density (kg/m³)
Higher density (128 kg/m³) provides better strength, durability, and longer service life. - Thickness
Thicker blankets offer better insulation but must balance space and installation constraints. - Application Environment
For aluminum processing, prioritize chemical stability and resistance to molten metal conditions.
Tips：
For most aluminum industry applications, we recommend:
👉 1260°C grade + 128 kg/m³ density + 25 mm thickness
This combination offers an optimal balance of insulation performance, durability, and cost.
What Problems Can Occur If Ceramic Fiber Blanket Is Selected Incorrectly?
Incorrect selection can reduce performance and increase operating costs.
Table 6. Common Issues Caused by Incorrect Selection
| Problem | Cause | Impact |
|---|---|---|
| Heat loss | Low density / thin | Higher energy cost |
| Shrinkage | Low temp grade | Insulation failure |
| Short life | Weak material | Frequent replacement |
| Instability | Poor installation | Safety risk |
| Contamination | Wrong material | Affects aluminum quality |
These issues can lead to increased costs, reduced efficiency, and potential process instability.
Expert Recommendation
To avoid these issues, always match the ceramic fiber blanket specification with your actual operating conditions. For aluminum processing systems, selecting the correct temperature grade and density is critical for ensuring long-term performance and process stability.
How AdTech Solutions Are Used in Aluminum Foundries
In aluminum foundries, insulation and filtration are often used together rather than as separate systems. AdTech combines ceramic fiber blanket with its filtration and degassing products to improve temperature stability and overall process efficiency.
Typical Integration Methods
- Backup insulation
Ceramic fiber blanket is commonly installed behind refractory castables or used as a removable lining in ladles and tundishes. This helps reduce heat loss and shortens reheating time during operation. - Surface reinforcement
In areas exposed to wear or airflow, the blanket can be paired with ceramic boards or cloth facings. This improves durability and reduces fiber shedding. - Working with filtration systems
When used together with AdTech ceramic foam filters and degassing units, the blanket helps maintain more stable temperatures. This can reduce energy consumption and improve melt cleanliness. - High-purity applications
For stricter requirements, high-purity blanket grades are typically used to ensure better chemical stability and consistency in molten aluminum environments.
Practical Notes
In most cases, performance depends on how well the system is matched to the application. This usually involves:
- Choosing the right blanket grade and density
- Selecting proper fixing or anchoring methods
- Adjusting the lining design based on furnace structure
- Considering alloy type and operating temperature
AdTech typically supports this during the quotation or pre-installation stage to avoid mismatches later on.
What This Improves
| Area | Result |
|---|---|
| Heat control | More stable temperature |
| Operation | Faster recovery time |
| Durability | Longer service life |
| Melt quality | Fewer inclusions |
| Cost | Lower energy and maintenance |
These improvements help optimize process stability, reduce operating costs, and enhance overall production efficiency.
