Industry Knowledge of Fused Cast AZS Brick

Fused Cast AZS (Alumina-Zirconia-Silica) bricks are high-quality refractory materials used in the glass industry for their excellent corrosion resistance and thermal stability. These bricks are made by electric melting of high-purity raw materials, which are then cast into moulds and cooled into solid shapes. The production process involves a series of intricate steps that ensure the final product meets the industry standard for quality and performance.

AZS bricks are classified into three grades, namely AZS-33, AZS-36, and AZS-41, based on their zirconia content. AZS-33 has the lowest zirconia content of around 33%, while AZS-41 has the highest at 41%. Generally, the higher the zirconia content, the better the corrosion resistance and thermal shock resistance of the bricks. These bricks are widely used in the glass industry, particularly in areas where the glass comes into contact with molten glass, glass melts, and super-heated steam.

The technical parameters of AZS bricks are another aspect that sets them apart from other refractory materials. These materials have high-density, high compressive strength, low porosity, and excellent erosion resistance. Additionally, they possess high thermal stability, low thermal expansion coefficient, and high thermal conductivity. These properties make AZS bricks the ideal material for use in severe glass furnace environments and increase their useful life.

The production process of AZS bricks involves three major stages: raw material preparation, melting process, and casting. The raw materials are prepared and mixed according to the specific formulation required for the production of each grade of AZS bricks. The next stage involves the electric melting of the mixture in a furnace at very high temperatures, usually above 2000 degrees Celsius. The molten mixture is then poured into moulds and left to cool and solidify into bricks. Each stage of the production process must be done meticulously to ensure that the finished product is of high quality and meets the set industry standards.

In conclusion, AZS bricks are an essential component in the glass industry, and their importance cannot be overemphasized. Their classification, technical parameters, and production process are all geared towards ensuring their effectiveness in severe glass furnaces and establishing their durability and longevity. With the growing demand for high-quality glass products, the production of AZS bricks remains a crucial component in the manufacturing process, ensuring the industry's continued growth.
