In high-temperature glass melting furnaces, where thermal shock and chemical erosion are constant threats, choosing the right refractory material isn’t just a technical decision—it’s a strategic one. Electric-fused AZS36 bricks have emerged as a preferred solution for operators seeking extended kiln life and consistent performance. But what makes them stand out?
The key lies in their precise chemical composition:
This optimized ratio creates a dense microstructure that resists penetration by alkali vapors and molten glass—a critical factor in reducing corrosion rates. Independent lab tests show this formulation achieves a corrosion rate of ≤1.3 mm/24h, significantly lower than standard AZS bricks (typically 2.5–4.0 mm/24h).
| Product Type | Cold Crushing Strength (MPa) | Corrosion Rate (mm/24h) | Density (g/cm³) |
|---|---|---|---|
| Standard AZS Brick | ≥ 270 MPa | 2.5–4.0 mm/24h | 3.65–3.75 |
| AZS36 Electric-Fused | ≥ 300 MPa | ≤ 1.3 mm/24h | ≥ 3.85 |
These numbers translate directly into operational savings: fewer replacements, less downtime, and improved energy efficiency across the production cycle. The volume density ≥ 3.85 g/cm³ and apparent porosity ≤ 1% further ensure minimal gas permeation and superior thermal shock resistance—key metrics often overlooked but vital in real-world applications.
What sets reputable manufacturers apart is not just chemistry—but consistency. Our AZS36 bricks comply with ISO 19963:2020 standards for electric-fused refractories, ensuring every batch meets strict criteria for purity, uniformity, and performance. This means you’re not buying a product—you’re investing in a process-backed solution that delivers predictable outcomes, even under extreme conditions.
One client in the Middle East reported a 40% increase in furnace campaign length after switching from conventional bricks to our AZS36 series—without any changes to their operating parameters. That’s not luck. It’s smart engineering.
Let us help you reduce unexpected shutdowns and optimize your refractory lifecycle with data-driven choices.
