As the aluminum industry places increasing emphasis on energy efficiency, equipment stability, and maintenance cost control, key thermal systems—such as tundishes, trough covers, and electrolytic cell linings—face growing challenges in their back-up insulation layers. On one hand, these areas are prone to heat buildup, back-up layer failure, and structural deformation under continuous high-temperature operation. On the other hand, traditional refractory materials like dense boards or castables are often heavy and have high thermal conductivity, making them unsuitable for modern lightweight and energy-efficient equipment designs.

Low Thermal Conductivity, Lightweight, High Compatibility: The Engineering Advantages of CCEWOOL Refractory Fiber Board in Aluminum Industry Applications

To address these issues, CCEWOOL refractory fiber board provides exceptionally low thermal conductivity and reduced weight, making it ideal for back-up insulation in tundishes, trough covers, and electrolytic cell structures. Even under high temperatures, the board maintains excellent thermal stability and mechanical strength. It resists cracking and delamination caused by thermal stress and offers high compatibility with complex aluminum equipment designs—supporting modular installation and on-site shaping with ease.

Precision Fiber Structure + Fully Automated Forming: The Process Behind High-Performance Refractory Fiber Boards

CCEWOOL refractory fiber boards are produced using high-purity spun fibers, developed in-house, and shaped via digitally controlled slurry mixing and fully automated vacuum forming systems. The result is a board with uniform fiber distribution and a dense internal core. Paired with intelligent drying and post-curing technologies, this process ensures excellent structural integrity and long service life, even in harsh operating conditions. These manufacturing strengths also guarantee consistent quality in large-scale production, giving customers reliable performance with every order.

Proven Performance in Tundish and Electrolytic Cell Applications: Real-World Energy Efficiency Gains

In real-world applications, CCEWOOL refractory fiber board has been widely adopted for tundish back-up insulation systems, electrolytic cell wall linings, and molten aluminum trough cover interiors. Customer feedback shows that after replacing traditional dense materials, overall equipment weight was reduced by more than 15%, surface temperature of furnace exteriors dropped by 18–22°C on average, and thermal efficiency improved significantly. Maintenance cycles were extended, and systems became more stable during long-term operation.
