In high-temperature industrial applications, the choice of refractory materials is crucial. High-temperature tanks, in particular, face a series of challenges, such as corrosion, thermal shock, and high-temperature creep. These issues can lead to reduced tank efficiency, increased maintenance costs, and even safety risks. Fortunately, AZS trough bricks have emerged as a reliable solution to these problems.

What are AZS Trough Bricks?

AZS trough bricks are fused alumina-zirconia-silicate refractory materials specifically designed for high-temperature tank applications. They are made by melting a mixture of high-purity raw materials in an electric furnace and then casting and solidifying them into a ceramic binder. This unique manufacturing process ensures the excellent quality and performance of AZS trough bricks.

Material Characteristics

The alumina-zirconia-silicate material used in AZS trough bricks offers several outstanding characteristics. With a high melting point of up to 2000°C, it can withstand extreme temperatures without significant deformation. Its chemical stability is excellent, making it resistant to corrosion from various molten metals and slag. For example, in comparison to traditional fireclay bricks, which may start to degrade at around 1300°C, AZS trough bricks maintain their integrity and performance at much higher temperatures.

Manufacturing Process

The manufacturing process of AZS trough bricks is a key factor in ensuring their high quality. First, carefully selected high-purity raw materials are mixed in a scientific ratio. Then, the mixture is melted in an electric furnace at a high temperature. Once melted, it is cast into the desired shape and allowed to solidify into a ceramic binder. This process not only enhances the density and strength of the bricks but also ensures uniform distribution of the components, resulting in consistent performance across all products.

Quality Standards and ISO Certification

AZS trough bricks meet strict quality standards thanks to the use of high-purity raw materials, scientific formulas, advanced manufacturing processes, and professional technical guidance. They have also obtained ISO international certification, which is a testament to their quality and reliability. This certification provides global buyers with confidence in the product's performance and consistency.

Real-World Applications

AZS trough bricks have been widely used in various high-temperature tank applications. In the glass industry, they are used in glass melting furnaces, where they resist the corrosion of molten glass and high temperatures, significantly extending the service life of the furnaces. In the metallurgical industry, they are applied in ladles and tundishes, providing reliable protection against molten metals and slag. For instance, a glass manufacturing plant reported a 30% increase in furnace service life after replacing traditional refractory materials with AZS trough bricks.
