Engineers working with glass melting furnaces know one truth: a single poor lining material choice can lead to unexpected downtime, increased energy costs, and reduced product quality. Many still rely on outdated assumptions—like choosing bricks based solely on price or brand familiarity—without fully understanding the real performance metrics that matter most.
Traditional zirconia-based refractories often perform well at first glance—especially when evaluated under lab conditions. But once installed in high-heat zones (typically above 1400°C), they begin to degrade rapidly due to glass phase crystallization and thermal stress. In fact, studies show that standard zirconia bricks can lose up to 3.5 mm per 24 hours under continuous exposure—a rate nearly 3x higher than modern alternatives.
| Material Type | Al₂O₃ (%) | ZrO₂ (%) | Porosity (%) | Corrosion Rate (mm/24h) |
|---|---|---|---|---|
| Standard Zirconia Brick | ≥35% | ≥25% | ≤3.5% | 3.5–5.0 |
| Electrofused AZS Brick TY-AZS36 | ≥49% | ≥35.5% | ≤1.0% | ≤1.3 |
The key difference? Microstructure density. TY-AZS36’s electrofused manufacturing process creates a near-zero-porosity matrix that resists molten glass penetration—even in aggressive areas like throat walls and electrode seals.
Not all parts of your furnace are created equal. Here’s how TY-AZS36 outperforms traditional materials in critical zones:
These aren’t just numbers—they’re results from actual installations across Europe, North America, and the Middle East where operators report fewer defects, lower maintenance frequency, and measurable reductions in fuel consumption.
Have you experienced frequent lining failures despite using “reputable” suppliers? You’re not alone—and it might be time to re-evaluate what truly drives longevity.
