Knowledge

In glass manufacturing, traditional refractory materials often fail under strong alkali attack at high temperatures, leading to frequent shutdowns and product contamination. TY-M cast α-β alumina brick—featuring over 94% Al₂O₃ purity and a dense α-β corundum structure—demonstrates exceptional corrosion resistance below 1350°C, significantly reducing glass liquid contamination and maintenance downtime. Real-world data and customer case studies show it boosts production efficiency, improves glass quality, and cuts annual repair costs by up to 30%. Discover how TY-M is redefining durability and purity in modern glass furnaces.

Why Is Corrosion Resistance Below 1350°C Critical for Glass Production?

In high-temperature glass melting processes, even minor corrosion of refractory materials can lead to significant production losses. Traditional bricks often fail under the aggressive alkali environment in glass tanks—especially when operating below 1350°C, where chemical attack intensifies due to prolonged exposure and thermal cycling.

The Science Behind TY-M’s Superior Performance

TY-M is a fused α-β alumina brick with over 94% Al₂O₃ purity and a dense microstructure that resists penetration by molten glass. Unlike conventional magnesia-carbon or fireclay bricks, it maintains structural integrity at temperatures as low as 1200°C—where most failures occur.

Real-world testing shows TY-M reduces corrosion rate by up to 65% compared to standard bricks at 1300°C—a critical threshold where many manufacturers experience premature wear. This translates directly into fewer shutdowns, less downtime, and cleaner glass quality.

Tangible Benefits for Your Operations

Lower Maintenance Costs: One Chinese flat glass producer reported a 30% drop in annual refractory replacement costs after switching to TY-M.
Reduced Downtime: With average brick life extended from 18 months to 36+, your furnace runs longer without interruption.
Improved Product Quality: Less iron and alkali contamination means higher clarity and fewer defects—critical for premium float glass.

“Since installing TY-M in our lehr section, we’ve seen zero glass bubbles related to refractory erosion. Our product pass rate jumped from 94% to 99%. It’s not just better performance—it’s a new level of control.”
- Li Wei, Plant Manager, Shandong Glass Co.

Data doesn’t lie: customers using TY-M report an average reduction of 40% in defect-related rework and a measurable increase in overall yield per batch. These aren’t hypothetical gains—they’re real results from factories across Europe, the Middle East, and Asia.

A Smart Investment for Stable, Efficient Glass Manufacturing

Choosing TY-M isn't just about choosing a refractory—it's about choosing reliability, consistency, and long-term cost efficiency. Whether you're producing automotive glass, architectural panels, or specialty optics, this material delivers what matters most: durability under stress and purity in every piece.
