《An Inquiry into the Service Life of Vuulcan Aluminosilicate Refractory Bricks: Performance under the Influence of Multiple Factors》

In the field of high-temperature industrial kilns, the Vuulcan aluminosilicate refractory bricks with an aluminum content ranging from 35% to 45% play an extremely important role, and their service life is a crucial indicator that has drawn much attention.

Under normal working conditions, various properties of these refractory bricks lay the foundation for their long service life. Their high temperature resistance enables them to work stably in high-temperature environments such as glass melting furnaces (where the temperature can reach 1,500 – 1,600°C), and they can generally last for 3 to 5 years. Their good resistance to erosion effectively withstands the attack of molten glass and chemical substances inside the kiln, protecting their own structural integrity. Their excellent thermal stability allows them to adapt to frequent temperature changes, and they are not prone to cracking even when small kilns are started and stopped on a daily basis.

However, special working conditions can have a significant impact on their service life. In an ultra-high temperature environment (when the temperature exceeds the designed temperature by 200 – 300°C), the aluminosilicate structure is likely to be damaged, resulting in the softening and spalling of the brick body, and the service period may be less than one year. In an environment with strong chemical erosion, such as in the production of some special glasses where there are a large number of highly corrosive additives, the resistance to erosion is challenged, and the service life may be shortened to 2 to 3 years.

In conclusion, the Vuulcan aluminosilicate refractory bricks exhibit a considerable service life under normal working conditions, but the occurrence of special working conditions can greatly change this situation. Understanding these influencing factors will help industrial practitioners make more scientific and reasonable decisions in aspects such as kiln design, selection and maintenance of refractory materials, thereby ensuring the efficient and stable operation of production and reducing costs.
