In the high-temperature environment of a glass melting furnace, selecting the right refractory brick isn't just about durability—it's about maximizing uptime, minimizing maintenance costs, and ensuring consistent product quality. Among the many options available, electrically fused AZS (alumina-zirconia-silica) brick TY-AZS36 stands out as a proven solution for side walls, throat zones, and critical hot spots.
TY-AZS36 typically contains over 36% ZrO₂ and 68–72% Al₂O₃—values that significantly exceed standard grades. With a bulk density of ~3.3 g/cm³ and a porosity below 12%, this brick offers exceptional resistance to chemical attack from molten glass and alkali vapors. Its dense microstructure minimizes penetration pathways, reducing secondary erosion by up to 40% compared to conventional bricks (based on field data from European glass plants).
| Property | TY-AZS36 Value | Standard AZS (33%) |
|---|---|---|
| ZrO₂ Content (%) | ≥36% | ~33% |
| Al₂O₃ Content (%) | 68–72% | ~65% |
| Apparent Porosity (%) | ≤12% | 15–20% |
| Thermal Shock Resistance (ΔT) | ≥1000°C | ~800°C |
A leading manufacturer in Saudi Arabia replaced their old AZS bricks with TY-AZS36 in the side wall and throat area of a 300-ton/day furnace. After 18 months of continuous operation, they reported:
This case illustrates how material science translates directly into operational savings—not just in parts replacement but also in labor, production loss, and safety risks.
Even the best materials need smart handling. Regular inspection every 4–6 weeks using infrared thermography can detect early signs of localized overheating or structural weakening. Also, avoid rapid temperature changes—maintain a controlled cooling curve during shutdowns to prevent microcracking.
With ISO 9001 and CE certifications, TY-AZS36 aligns with global standards for both performance and environmental responsibility—supporting your green manufacturing goals while delivering measurable ROI.
