During the operation of glass melting furnaces, the back-lining serves as a critical insulation layer within the high-temperature structure. Its performance directly impacts the furnace's thermal efficiency and operational stability. However, traditional insulation materials tend to suffer from structural collapse, thermal conductivity degradation, and thermal shock damage under prolonged high temperatures—failing to meet the increasingly demanding requirements of the glass industry for efficient and stable performance.

To address these challenges, CCEWOOL Ceramic Fiber Back-lining Board offers outstanding engineering adaptability for furnace back-up lining applications in the glass industry. With its low thermal conductivity, high strength, and excellent thermal shock resistance, the product maintains structural integrity and insulation performance even in long-term service above 1000°C. This significantly extends the lifespan of the furnace lining, reduces energy loss, and improves overall operational efficiency.

The exceptional performance of CCEWOOL refractory ceramic board under extreme conditions stems from our deeply optimized manufacturing processes. We adopt an electric furnace melting and fiber-spinning technique combined with high-precision vacuum forming to ensure uniform fiber diameter and dense internal structure. The finished boards are free of voids and cracks, providing enhanced mechanical strength and thermal stability. In addition, automatic temperature-controlled drying and secondary high-temperature sintering processes further improve the board's resistance to deformation and thermal shock in cyclic thermal environments—meeting the demands of complex furnace operations in the glass industry.

Thanks to this advanced production technology, CCEWOOL refractory ceramic board has successfully resolved long-standing issues faced by glass manufacturers, including insulation degradation and structural instability in furnace back-up linings. According to customer feedback, the use of CCEWOOL boards has significantly improved furnace thermal efficiency, reduced maintenance frequency, and enabled more energy-efficient and stable operations.
