Introduction to the Refractory Challenge in High-Temperature Troughs

In the industrial sector, high-temperature troughs face significant refractory challenges. Traditional refractory materials often struggle to withstand extreme temperatures, leading to frequent replacements and high maintenance costs. For example, in some high-temperature smelting processes, traditional refractory materials may need to be replaced every 3 - 6 months, causing disruptions to production and increasing overall costs.

Characteristics of Fused Alumina Zirconium Silicate Material

AZS trough bricks are made of fused alumina zirconium silicate material, which has unique characteristics. This material has a high melting point, typically around 1800 - 2000°C, much higher than many other common refractory materials. For instance, compared with some ordinary clay-based refractory materials with a melting point of about 1200 - 1400°C, AZS trough bricks can better withstand high temperatures in high-temperature troughs.

In addition, it has excellent corrosion resistance. In harsh chemical environments, such as those containing strong acids or alkalis, the corrosion rate of AZS trough bricks is only about 5 - 10% of that of some other refractory materials, which significantly extends the service life of the troughs.

Manufacturing Process: Electric Furnace Melting and Casting

The manufacturing process of AZS trough bricks is mainly electric furnace melting and casting. This process ensures the uniform distribution of components in the bricks. During the melting process, the raw materials are heated to a high temperature in an electric furnace, usually around 1900°C, and then cast into the desired shape. This manufacturing process can eliminate internal defects in the bricks, such as pores and cracks, effectively improving the density and strength of the bricks. The density of AZS trough bricks produced by this process can reach 3.5 - 3.8 g/cm³, which is much higher than that of some other refractory materials.

Quality Assurance: High-Purity Raw Materials, Scientific Formulation, and ISO Certification

High-purity raw materials are used in the production of AZS trough bricks. The purity of alumina in the raw materials can reach over 95%, and the purity of zirconia can reach over 30%. Combined with a scientific formulation, these high-purity raw materials ensure the excellent quality of the bricks.

Moreover, the production of AZS trough bricks complies with ISO international standards. ISO certification not only guarantees the quality of the products but also reflects the strict quality control system of the manufacturer. This provides a strong guarantee for global procurement managers, allowing them to have full confidence in the products.

Real-World Application Cases

In a glass manufacturing plant, after using AZS trough bricks in their high-temperature melting troughs, the service life of the troughs was extended from the original 6 - 8 months to over 2 years. This not only reduced the frequency of trough replacements but also significantly improved production efficiency, saving the plant approximately 30% in maintenance and replacement costs.

In a metal smelting plant, AZS trough bricks were used in the high-temperature launders. Due to their excellent corrosion resistance and high-temperature resistance, the launders could operate stably for a long time, reducing production interruptions caused by trough damage and increasing the annual output of the plant by about 20%.
