AZS33-Y

AZS33-Y is an electrically fused zirconia-alumina brick produced by the oxidation method, containing approximately 33% zirconia. With its dense texture and stable performance, it is a reliable choice for critical high-temperature areas in glass melting furnaces.

Key Features:

High Resistance to Glass Melt Erosion: The approximately 33% zirconia content forms a protective layer upon contact with the glass melt, effectively resisting erosion by sodium-calcium glass and extending the furnace’s service life.

Excellent Thermal Shock Resistance: With a low coefficient of thermal expansion and a uniform crystal structure, it withstands rapid cooling and heating without cracking or spalling.

Extremely Low Contamination: The oxidation process minimizes the leaching of residual carbon and glass phases, ensuring the purity of the molten glass and reducing defects such as stone formation and bubbles.

Tight Joints: CNC precision grinding ensures dimensional accuracy, allowing bricks to interlock tightly and preventing glass melt penetration and upward drilling erosion.

Applications:

Tank wall liquid level lines, tank bottom lining, upper structures, and feed channels. Suitable for bottle and jar glass, tableware glass, and float glass melting furnaces.
