In the steel industry, where energy efficiency directly impacts production costs and environmental compliance, optimizing furnace insulation is no longer optional—it’s a strategic imperative. One material that consistently delivers measurable results? Zirconia-based flexible ceramic fiber blanket.
Heat Loss Reduction: Up to 35% compared to traditional refractory bricks in continuous casting furnaces.
Thermal Conductivity: As low as 0.03 W/m·K at 1000°C—over 40% lower than standard insulating bricks.
Weight Savings: 70% lighter than dense firebrick linings, reducing structural load on furnace walls.
Unlike rigid modules or heavy brick systems, flexible zirconia ceramic fiber blankets offer unmatched thermal performance and installation flexibility. With a maximum continuous working temperature of up to 1800°C, they maintain integrity even under extreme conditions found in steel reheating and soaking zones.
Real-world data from a mid-sized steel mill in Germany shows a 32% drop in heat loss after retrofitting their preheating chamber with our fiber blanket. The facility reported an annual savings of over €85,000 in fuel costs—while also improving worker safety due to reduced surface temperatures.
Proper installation ensures long-term performance. Key steps include:
Common mistakes? Skipping surface prep or using incompatible fasteners can lead to premature failure—even if the material itself is top-tier.
| Feature | Flexible Ceramic Fiber Blanket | Traditional Refractory Brick |
|---|---|---|
| Thermal Conductivity (W/m·K @ 1000°C) | 0.03–0.04 | 0.7–1.2 |
| Installation Time | ~40% faster | Time-intensive |
| Maintenance Frequency | Every 2–3 years | Every 6–12 months |
