AZS brick is a widely used heat-resistant fireproof material. AZS consists of abbreviations of the English words Alumina (alumina), Zirconia (zirconium dioxide) and Silica (silicon dioxide). It is a special fireproof material with high temperature stability, excellent wear resistance and corrosion resistance, which is widely used in high temperature industrial fields, such as glass melting furnaces.

AZS brick classification
Fused zirconium corundum bricks are divided into three types depending on the zirconium dioxide content: from 33% to 41%, AZS-33#, AZS-36# and AZS-41#. Zirconium dioxide content varies, and the purpose of the USA is also different, Please, contact us for more details.
Fused zirconium corundum brick AZS33
Atopic dermatitis 33 is the most widely used product in the AZS series of melting and casting products. It has excellent performance in preventing molten glass contamination and is widely used in the most critical parts of the pool wall, pool bottom, upper structure of melting basin and feed channel.
Fused zirconium corundum brick AZS36
AZS36 – This is a product with excellent performance characteristics when casting ASS series products. It has high resistance to glass erosion by liquid and low contamination. Commonly used in glass furnaces, where the glass fluid supply speed is high or the temperature is high.
Fused zirconium corundum brick AZS41
ASS 41 – It is a product of ASUS melting and casting series with excellent performance. AZS41 has good glass erosion resistance and extremely low molten glass contamination, so it is used in key parts of glass furnaces, such as the walls of a swimming pool, loading openings, angles, all-electric smelting furnace combs and other parts.
