In the field of glass production, the stability of glass melting furnaces is of utmost importance. It directly affects the quality and efficiency of glass manufacturing. Among the various materials used in glass melting furnaces, AZS cast blocks (electrically fused AZS 33# blocks) have emerged as a crucial component, playing a significant role in ensuring the stable operation of these furnaces.
AZS cast blocks are made from pure alumina powder and zircon sand. This unique combination of raw materials gives these blocks a dense and uniform microstructure. Under a microscope, the structure of AZS cast blocks appears as a tightly packed matrix, which is quite different from other common materials used in glass melting furnaces. The dense microstructure is the key to the excellent performance of AZS cast blocks.
The pure alumina powder provides high strength and heat resistance, while the zircon sand contributes to the formation of a stable crystal structure. Together, they create a material that can withstand the harsh conditions inside a glass melting furnace, including high temperatures, corrosive glass melts, and mechanical stress.
One of the most significant advantages of the dense microstructure of AZS cast blocks is their strong resistance in the glass melt. When in contact with the high - temperature glass melt, the dense structure prevents the penetration of the glass melt into the block, reducing the risk of block erosion and damage. This resistance is crucial for maintaining the integrity of the furnace lining and ensuring the smooth flow of the glass melt.
Moreover, the dense microstructure helps to avoid the problem of solidification. In a glass melting furnace, if the material has a porous structure, the glass melt may solidify inside the pores, leading to blockage and uneven heat distribution. The dense AZS cast blocks eliminate this problem, allowing the glass melt to flow freely and maintaining a stable temperature throughout the furnace. This stability is essential for producing high - quality glass products with consistent properties.
AZS cast blocks are widely used in many key parts of glass melting furnaces. They are commonly found in the throat, the area where the glass melt flows from the melting chamber to the working chamber. The strong resistance of AZS cast blocks in this area ensures the smooth transfer of the glass melt and prevents the formation of impurities.
They are also used in the sidewalls and the bottom of the melting chamber. These parts are exposed to the highest temperatures and the most corrosive glass melts. The use of AZS cast blocks in these areas significantly extends the service life of the furnace and reduces maintenance costs. Additionally, AZS cast blocks can be found in the regenerator, where they help to improve the heat - exchange efficiency and save energy.
In conclusion, the AZS cast blocks, with their unique composition and dense microstructure, offer numerous benefits for glass melting furnaces. Their strong resistance in the glass melt, ability to avoid solidification, and wide applications in key furnace parts make them an ideal choice for ensuring the stable operation of glass melting furnaces.
Selecting AZS cast blocks is a wise decision for glass manufacturers. It not only guarantees the quality of glass products but also improves the efficiency of glass production. By reducing furnace downtime and maintenance costs, AZS cast blocks contribute to the overall profitability of glass manufacturing enterprises.
