Electro - fused AZS refractory bricks, especially the TY - AZS36D model, have long been a cornerstone in the construction of float glass furnaces. With over 30 years of process experience, these bricks have achieved remarkable stability. Let's start by delving into the manufacturing process, which begins with the crucial step of raw material screening.
The first step in the manufacturing of electro - fused AZS refractory bricks is the selection of high - purity raw materials. Only the finest raw materials are chosen to ensure the high - quality of the final product. The precise ratio of these raw materials is the key to the excellent performance of the bricks. For example, the specific combination of different minerals can enhance the overall strength and stability of the refractory bricks. Our 30 - year experience in the industry allows us to have a deep understanding of the characteristics of various raw materials, enabling us to make the most appropriate selection and ratio.
Once the raw materials are well - mixed, they are sent to the electric furnace for melting. The melting process in the electric furnace is a complex one that requires strict temperature control. The temperature in the electric furnace can reach extremely high levels, usually above 2000°C. Under such high - temperature conditions, the raw materials gradually melt into a liquid state. This melting process is not only a physical change but also a chemical reaction process, which changes the internal structure of the raw materials and lays the foundation for the excellent performance of the refractory bricks.
After the raw materials are melted into a liquid state, they are poured into the mold. The pouring process needs to be carried out carefully to ensure the uniform distribution of the liquid in the mold. Then, a scientific cooling system is adopted. The cooling rate has a significant impact on the internal structure of the refractory bricks. A reasonable cooling system can make the internal structure of the bricks more compact, thereby improving their strength and stability.
One of the key steps in the manufacturing of electro - fused AZS refractory bricks is the oxidation process. This process can effectively reduce the content of Na₂O/K₂O in the bricks. The reduction of the content of these alkali metals has a profound impact on the glass - phase structure of the refractory bricks. When the content of Na₂O/K₂O is reduced, the glass - phase structure becomes more stable. For example, the glass - phase precipitation temperature can reach ≥1400°C, which is much higher than that of traditional AZS refractory bricks. This high glass - phase precipitation temperature indicates that the electro - fused AZS refractory bricks have better stability in high - temperature environments.
Based on 30 years of industry experience, we have summarized a series of strategies to deal with common problems in kiln operation. For example, during the long - term operation of the kiln, problems such as corrosion and crystallization may occur. The electro - fused AZS TY - AZS36D refractory bricks have excellent anti - corrosion and anti - crystallization abilities. Their anti - corrosion ability is significantly better than that of traditional AZS refractory bricks. In practical applications, the service life of TY - AZS36D in the kiln can be extended by at least 20% compared with traditional refractory bricks.
There are many practical cases that prove the long - term stable performance of TY - AZS36D in high - temperature environments. In a certain large - scale float glass factory, the TY - AZS36D refractory bricks were used in the float glass kiln. After several years of operation, the kiln still maintained good operating conditions. The bricks showed no obvious signs of corrosion or damage, which fully demonstrated their excellent performance in high - temperature and harsh environments.
In conclusion, electro - fused AZS TY - AZS36D refractory bricks, with their excellent manufacturing process, oxidation process, and long - term stable performance in practical applications, are the ideal choice for float glass kilns. For engineering technicians, procurement decision - makers, and kiln operation and maintenance personnel, understanding the technical principles and application scenarios of these refractory bricks is of great significance.
