Glass furnaces are the heart of the glass manufacturing industry, but frequent damage to the side walls of glass furnaces has been a persistent headache for operators. This article aims to provide in - depth insights into the anti - erosion technology and application of the fused AZS brick TY - AZS36, offering practical solutions to this long - standing problem.
The high corrosion resistance and thermal shock performance of the fused AZS brick TY - AZS36 are attributed to its unique chemical composition and microstructure. It contains approximately 36% ZrO₂ and a high percentage of Al₂O₃, usually around 55 - 60%. These high - content elements contribute significantly to its excellent performance.
The brick has a dense microstructure with a low apparent porosity, typically less than 2%. This dense structure effectively prevents the penetration of molten glass and corrosive substances, enhancing its anti - erosion ability. As shown in Figure 1, the microscopic view reveals the compact arrangement of crystals, which is the key to its high - performance characteristics.
The fused AZS brick TY - AZS36 has demonstrated remarkable advantages in multiple key positions of glass furnaces. In the side walls of glass furnaces, it has been reported that the service life can be extended by up to 3 - 5 years compared to traditional refractory bricks. For example, in a large - scale glass manufacturing plant in Germany, after replacing the side - wall refractory bricks with TY - AZS36, the frequency of side - wall repairs decreased from once every 1 - 2 years to once every 4 - 5 years, greatly reducing maintenance costs.
In the ventilation ports and throats of glass furnaces, the high - temperature resistance and anti - erosion performance of TY - AZS36 are also crucial. These areas are subject to high - velocity hot gas flow and corrosive substances. In a practical application in a Chinese glass factory, the use of TY - AZS36 in the ventilation ports reduced the corrosion rate by 60%, ensuring stable ventilation and improving the overall efficiency of the furnace.
To ensure the long - term stable performance of the fused AZS brick TY - AZS36, regular maintenance and inspection are essential. A systematic daily inspection plan should be established, including visual inspection at least once a week and detailed non - destructive testing every three months. For example, ultrasonic testing can be used to detect internal cracks and damage.
During the maintenance process, it is important to maintain a stable operating temperature of the furnace. Fluctuations in temperature can cause thermal stress on the refractory bricks, accelerating their damage. By keeping the temperature within a narrow range, usually ± 50°C, the service life of the bricks can be effectively extended.
The fused AZS brick TY - AZS36 is ISO 9001 and ISO 14001 certified, which indicates its high - quality manufacturing process and environmental - friendly production. In today's market, more and more customers are concerned about product quality and environmental protection. The ISO certification not only guarantees the quality of the product but also reflects the company's commitment to sustainable development.
The green manufacturing process of TY - AZS36 reduces energy consumption by 20% compared to traditional manufacturing methods, which is in line with the global trend of energy conservation and environmental protection. This not only benefits the environment but also helps companies reduce production costs in the long run.
In conclusion, the fused AZS brick TY - AZS36 offers a comprehensive solution to the problem of frequent damage to glass furnace side walls. Its excellent anti - erosion technology, high - temperature performance, and environmental - friendly manufacturing process make it an ideal choice for glass furnace operators.
