High-Performance Electrofused AZS Refractories: Why TY-AZS36D Delivers Longer Service Life in Glass Manufacturing

In the demanding world of glass production—where temperatures exceed 1500°C and chemical erosion is constant—refractory materials must perform under extreme conditions. The TY-AZS36D electrofused AZS (alumina-zirconia-silica) refractory series stands out as a benchmark solution for modern glass furnaces, especially in float glass and bottle kilns.

From Raw Material to Precision Casting: A Proven Process

The secret behind TY-AZS36D lies not just in its composition but in how it’s made. Using high-purity alumina (≥99.5%), zirconia (ZrO₂ ≥ 60%), and silica (SiO₂ ≤ 1%) sourced from certified suppliers, our formulation reduces Na₂O+K₂O content to below 0.5%—a critical threshold for minimizing glass phase instability during thermal cycling.

Through controlled oxidation in electric arc furnaces (typically at 1800–2000°C), we achieve uniform melting without introducing unwanted impurities. This process mimics industrial steelmaking—where precision control leads to superior metallurgy—and results in a dense, homogeneous microstructure that resists both chemical attack and mechanical stress.

Real-World Performance: 18+ Months Without Erosion

At a Tier-1 European flat glass manufacturer, TY-AZS36D bricks installed in the crown and sidewall regions of a continuous float furnace operated continuously for over 18 months—with no visible signs of structural degradation or crystallization. In comparison, conventional fused cast AZS bricks showed measurable wear after just 12 months.

This extended service life translates directly into cost savings: reduced downtime, fewer replacements, and lower maintenance labor. One customer reported a 35% decrease in annual refractory-related operational costs after switching to TY-AZS36D across their entire line.

Why Engineers Trust TY-AZS36D

With over 30 years of experience serving global glass producers—from China to the U.S. and Middle East—we’ve refined this product based on real-world feedback and ISO 9001-certified quality systems. Our engineers don’t just sell a brick—they offer a data-backed performance guarantee.

Whether you're designing a new furnace or optimizing an existing one, choosing TY-AZS36D means investing in reliability, consistency, and long-term ROI—not just short-term savings.
