In high - temperature industrial applications, the refractory problem of high - temperature tanks has always been a major challenge for global procurement decision - makers. High - temperature tanks are widely used in glass manufacturing, non - ferrous metal smelting, and other industries, and their refractory materials directly affect the efficiency, quality, and service life of the entire production process. Fortunately, there is a material that can effectively solve these problems - AZS trough bricks.

Material Characteristics of AZS Trough Bricks

AZS trough bricks are fused alumina - zirconia - silicate refractory materials specifically designed for high - temperature tank applications. Compared with other common refractory materials such as ordinary magnesia - chrome bricks and cast big mullite bricks, AZS trough bricks have significant advantages. For example, ordinary magnesia - chrome bricks have a refractoriness under load of about 1550°C, while AZS trough bricks can withstand temperatures up to 1750°C, providing more reliable high - temperature resistance for high - temperature tanks.

In terms of corrosion resistance, the corrosion rate of AZS trough bricks in contact with molten glass is only 0.5mm/year, much lower than that of other materials. This excellent corrosion resistance ensures the long - term stability of high - temperature tanks and reduces the frequency of equipment replacement and maintenance.

Manufacturing Process of AZS Trough Bricks

The manufacturing process of AZS trough bricks is a key factor in ensuring their high quality. It involves electric furnace melting, casting, and solidification to form a ceramic binder. First, high - purity raw materials are selected, including alumina, zirconia, and silica. These raw materials are precisely proportioned and then melted in an electric furnace at a high temperature of about 2000°C. After melting, the molten material is poured into a pre - designed mold and undergoes a slow solidification process to form a dense and uniform structure.

This manufacturing process not only ensures the high density and low porosity of the bricks but also effectively improves their mechanical strength and thermal shock resistance. For example, the compressive strength of AZS trough bricks can reach 500MPa, which is much higher than that of many traditional refractory materials.

Quality Standards and ISO Certification

To ensure the quality of AZS trough bricks, strict quality control measures are implemented throughout the production process. High - purity raw materials play a crucial role in improving product quality. Only by using raw materials with a purity of over 99% can we ensure the excellent performance of the final product.

In addition, obtaining ISO international certification is also an important symbol of product quality. ISO certification indicates that the production process of AZS trough bricks meets international standards, which provides strong support for global procurement decision - makers to choose our products.

Practical Application Cases

Let's take a glass manufacturing enterprise as an example. Before using AZS trough bricks, the high - temperature tank of this enterprise needed to be repaired every 6 months due to severe corrosion and damage of the refractory materials, which seriously affected production efficiency. After replacing with AZS trough bricks, the service life of the high - temperature tank was extended to 3 years, and the production efficiency was increased by 30%. This case clearly demonstrates the significant advantages of AZS trough bricks in practical applications.

In conclusion, AZS trough bricks are an ideal solution for high - temperature tank refractory problems. If you are still troubled by the refractory problems of high - temperature tanks, don't miss this excellent material.
