AZS Refractory Bricks Properties, Manufacturing, applications & pricing
What Is AZS Refractory Brick？ Fused cast AZS refractory bricks—commonly known as AZS 33#, AZS 36#, and AZS 41#—are the most essential refractory materials used in the global glass industry. Whether producing flat glass, container glass, photovoltaic glass, daily glass, or special glass products, the durability and stability of a glass melting furnace depend heavily on the performance of its AZS bricks. A modern glass furnace operates continuously for 5–10 years at temperatures above 1500°C, pushing materials to their structural limits. Under such extreme heat, molten glass attacks the refractory lining through chemical dissolution, erosion, thermal shock, alkali corrosion, and glass phase penetration. In this harsh environment, only fused cast AZS bricks—made from alumina (Al₂O₃), zirconia (ZrO₂), and silica (SiO₂)—can provide the long-term resistance required for furnace longevity. AZS refractory bricks combine the corrosion resistance of zirconia, the thermal stability of alumina, and the structural bonding strength created by the glassy matrix formed during the casting process. This unique combination gives fused cast AZS bricks unmatched performance in molten glass environments. Their role is fundamental: they ensure the structural integrity of the melting tank, reduce glass defects, maintain thermal balance, and significantly extend furnace life. Without AZS bricks, industrial-scale glass...
