Glass melting furnaces are the heart of the glass manufacturing industry, but they often face severe corrosion problems. These issues can lead to reduced furnace lifespan, increased maintenance costs, and compromised product quality. In this context, fused AZS TY - AZS33 emerges as a revolutionary solution, offering enhanced corrosion resistance and durability for glass melting furnaces.
AZS33 is made from pure alumina powder and zircon sand. Its chemical composition is a key factor in its excellent performance. It contains approximately 65% ZrO2 and 34% SiO2, along with a small amount of Al2O3. This unique combination forms an Al2O3 - ZrO2 - SiO2 ternary system, which is the foundation for its superior corrosion resistance.
The Al2O3 - ZrO2 - SiO2 system in AZS33 forms a dense microstructure. This structure effectively resists the penetration and chemical attack of molten glass. When in contact with molten glass, the zirconia (ZrO2) and silica (SiO2) in AZS33 work in synergy. Zirconia has high melting point and chemical stability, which can form a protective layer on the surface of the material. Silica can fill the gaps in the structure, further enhancing its density and reducing the porosity. As a result, the material can withstand the harsh environment of high - temperature molten glass for a long time.
Ordinary refractory materials often suffer from rapid deterioration in high - temperature molten glass environments. They may experience cracking, spalling, and chemical erosion, which significantly shortens their service life. In contrast, AZS33 maintains its integrity and performance under the same conditions. For example, in a glass melting furnace operating at 1500°C, ordinary refractory materials may need to be replaced every 6 - 8 months, while AZS33 can last for 18 - 24 months, reducing the frequency of furnace shutdowns and maintenance costs.
AZS33 has a wide range of applications in glass melting furnaces. It is commonly used in critical parts such as the upper structure, side walls of the working tank, paving bricks, and charging channels. In the upper structure, it can prevent the penetration of hot gases and dust, protecting the furnace roof. In the charging channel, it can resist the impact and corrosion of the incoming raw materials. In the side walls of the working tank, it ensures the stability of the molten glass level and prevents leakage.
Many glass manufacturers have already benefited from using AZS33. For instance, a large - scale glass factory in Europe replaced its traditional refractory materials with AZS33 in its melting furnace. As a result, the furnace's service life was extended by 50%, and the number of furnace shutdowns was reduced by 40%. This not only saved a significant amount of maintenance costs but also increased the production efficiency and product quality.
The choice of AZS33 is a strategic decision for glass manufacturers. Its unique chemical composition and dense microstructure provide long - term corrosion resistance, which is crucial for ensuring the longevity of glass melting furnaces and the quality of glass products. With AZS33, glass manufacturers can reduce production interruptions, lower maintenance costs, and improve overall productivity.
In conclusion, AZS33 is a game - changer in the field of glass melting furnace refractory materials. Its excellent corrosion resistance, combined with its wide range of applications and proven performance in real - world scenarios, makes it the preferred choice for high - end glass factories. If you are looking to enhance the durability of your glass melting furnace and improve your product quality, don't miss out on the opportunity to use AZS33.
