The AZS cast block is based on the Al2O3 - ZrO2 - SiO2 ternary system. The unique combination of these three main components forms the basis for its excellent performance. The formation mechanism of its dense microstructure is closely related to the melting and solidification processes during production. When the raw materials are melted at high - temperatures, a series of complex chemical reactions occur. As the melt cools and solidifies, the Al2O3, ZrO2, and SiO2 form a highly ordered and dense structure. This structure is not only compact but also has a uniform distribution of elements, which is crucial for its subsequent performance in extreme conditions.
In the extreme working conditions of glass furnaces, such as high temperatures, thermal cycling, and glass liquid erosion, the AZS cast block shows excellent thermal shock stability and chemical inertness. The dense microstructure can effectively resist the penetration of high - temperature glass liquid and chemical substances. Under high - temperature conditions, the structure can maintain its integrity, preventing the material from cracking due to thermal stress. In thermal cycling environments, the material can withstand repeated heating and cooling without significant damage. For example, in some glass furnaces with frequent start - stop operations, the AZS cast block can still maintain its performance after hundreds of thermal cycles.
In terms of chemical inertness, the AZS cast block can resist the corrosion of various chemical substances in the glass liquid. The glass liquid often contains various metal oxides and salts, which can cause severe corrosion to common materials. However, the AZS cast block can maintain its chemical stability, effectively protecting the structure of the glass furnace and extending its service life.
In glass furnaces, the AZS cast block has a wide range of applications. In the upper structure of the glass furnace, it can withstand high - temperature flue gas and thermal radiation, effectively protecting the furnace roof. The use of AZS cast blocks in this area can extend the service life of the upper structure by more than 30%. In the side walls of the glass furnace, which are in direct contact with the glass liquid, the AZS cast block can resist the erosion of the glass liquid, reducing the wear rate of the side walls and reducing the frequency of kiln shutdown for maintenance.
In the charging channel, where materials are continuously fed into the furnace, the AZS cast block can withstand the impact and abrasion of materials. The use of AZS cast blocks in the charging channel can significantly improve the wear - resistance of the channel, ensuring the smooth operation of the charging process. Specific data shows that in some glass furnaces, after using AZS cast blocks in the charging channel, the service life of the channel has been extended by 2 - 3 times.
Proper installation and maintenance are crucial for the performance of AZS cast blocks. During installation, it is necessary to ensure that the blocks are installed tightly to prevent gaps from forming, which could lead to the penetration of high - temperature gas and glass liquid. The installation surface should be flat and clean to ensure good contact between the blocks. In daily maintenance, regular inspections are required to check for cracks, wear, and other issues. If any problems are found, timely repairs or replacements should be carried out.
For example, in a large - scale glass manufacturing enterprise, by strictly following the installation specifications and carrying out regular maintenance, the service life of the AZS cast blocks in their glass furnaces has been extended by an average of 40%, and the frequency of kiln shutdown for maintenance has been reduced by more than half.
Many customers in the glass manufacturing industry have given positive feedback on the use of AZS cast blocks. A well - known glass manufacturer said in a quote: "Since we started using AZS cast blocks in our glass furnaces, the service life of the furnaces has been significantly extended, and the production efficiency has been greatly improved. We have reduced a lot of maintenance costs and production interruptions." Another customer mentioned that the use of AZS cast blocks has enabled them to produce higher - quality glass products because the stable performance of the furnace has reduced the impact of furnace problems on the glass quality.
In conclusion, the AZS cast block, with its excellent performance in glass furnaces, is an ideal choice for glass manufacturing enterprises.
