Product Description

Product Description

AZS Fused Cast Refractory Block is a high-performance zirconia–corundum refractory material specially designed for glass melting furnaces operating under severe chemical corrosion and high-temperature conditions.

Manufactured by the fused casting process, AZS blocks provide excellent resistance to molten glass corrosion, low blister formation, and long service life, making them the preferred choice for critical glass furnace zones such as sidewall, tank bottom, and throat.

Features

Excellent Glass Corrosion Resistance
High ZrO2 content effectively resists glass melt erosion and penetration.

Dense Fused Cast Structure
Fused casting ensures high density, low porosity, and stable crystal structure.

Stable High-Temperature Performance
Suitable for long-term operation in glass furnaces with minimal deformation.

Low Defect Formation
Helps reduce glass defects such as stones, cords, and bubbles.

Customized Block Design
Blocks can be machined according to furnace drawings and installation positions.

Applications

Glass furnace sidewall
Glass furnace tank bottom
Throat and channel areas
Regenerator zones
