If your furnace’s vent port refractories are showing signs of rapid wear—cracking, spalling, or unexpected erosion—it's likely not just about material quality. In fact, over 60% of premature failures in glass melting furnaces stem from poor thermal management and inadequate maintenance practices, rather than the inherent limitations of the brick itself.
TY-AZS36 is engineered for extreme conditions. With a minimum alumina (Al₂O₃) content of 49% and zirconia (ZrO₂) at 35.5%, this electric-fused brick offers superior resistance to chemical attack by molten glass at temperatures exceeding 1600°C. Its density exceeds 3.85 g/cm³, meaning it has minimal porosity—less than 12%—which significantly reduces penetration by corrosive gases and molten glass phases.
| Property | Value | Benefit |
|---|---|---|
| Al₂O₃ Content | ≥49% | High corrosion resistance |
| ZrO₂ Content | ≥35.5% | Excellent thermal shock stability |
| Density | ≥3.85 g/cm³ | Low gas permeability & high strength |
In multiple case studies across Europe and Southeast Asia, TY-AZS36 bricks installed in vent ports, throat zones, and electrode seals showed average wear rates of ≤1.3 mm per 24 hours under continuous operation. That’s nearly 3x slower than standard castable bricks. Operators report fewer unplanned shutdowns and reduced downtime costs—often saving $15k–$25k per furnace cycle when extended from 6 months to 12+ months.
These steps create a closed-loop maintenance system that turns reactive fixes into proactive care—key for maximizing ROI on high-value refractory investments.
Manufactured under ISO 9001-certified processes, TY-AZS36 aligns with global sustainability goals by reducing waste and energy loss from frequent replacements. It’s trusted by leading glass producers in Germany, UAE, and China—not just for performance, but for reliability you can count on.
