Case Study: Application of Low-Sodium Refractory Materials in Float Glass Production - Empirical Evidence of Extending Furnace Life and Reducing Defects

In the float glass production process, the stability of furnace lining materials directly determines the quality of the glass and the service life of the equipment. This article delves into how low-sodium refractory materials, such as TY - AZS36D, enhance the stability of the glass phase and anti - crystallization ability by reducing the Na₂O content (≤1.35%). Empirical cases show that they can extend the service life of the furnace and significantly reduce glass defects. By combining the chemical mechanism of the materials and on - site application data, it provides a scientific basis for material selection for technicians and procurement decision - makers, helping enterprises reduce costs and increase efficiency.

The Technical Requirements of the Float Glass Industry for High - Reliability Refractory Materials

The float glass industry has a high demand for refractory materials with high reliability. These materials need to withstand high temperatures and strong chemical corrosion during the glass melting process. The quality of refractory materials not only affects the quality of the glass but also has a significant impact on the production cost and efficiency of the enterprise. For example, a high - quality refractory material can reduce the frequency of furnace repairs and replacements, thus saving a lot of time and cost for the enterprise.

The Key Impact Mechanism of Na₂O Content on Glass Phase Precipitation Temperature and Corrosion Resistance

The Na₂O content in refractory materials plays a crucial role in the glass phase precipitation temperature and corrosion resistance. A lower Na₂O content can increase the glass phase precipitation temperature, making the glass phase more stable. At the same time, it can also improve the corrosion resistance of the refractory material, reducing the erosion of the furnace lining by the molten glass. The following table shows the comparison of Na₂O content in different refractory materials:

As shown in the table, the Na₂O content in TY - AZS36D is significantly lower than that in ordinary AZS, which gives it better performance in terms of glass phase stability and corrosion resistance.

Real - World Customer Cases of TY - AZS36D Application

Let's take a look at some real - world customer cases to see the application effects of TY - AZS36D. In a glass bottle kiln, TY - AZS36D was used on the side wall of the bottle kiln. After a period of use, it was found that the service life of the furnace was extended by about 2 - 3 years compared with the previous use of ordinary refractory materials. At the same time, the number of glass defects was reduced by about 30%, greatly improving the quality of the glass products.

In another case, TY - AZS36D was used in the production of floor tiles. The high - temperature resistance and corrosion resistance of TY - AZS36D ensured the stability of the production process, and the defect rate of floor tiles was reduced by about 20%. The following is a quote from a customer:

"Since we started using TY - AZS36D in our kiln, we have noticed a significant improvement in the quality of our glass products and a reduction in production costs. The service life of the furnace has also been extended, which is really a great investment for our enterprise." - [Customer Name]

Enhancing Professional Credibility with ISO Certification and Typical Indicators

TY - AZS36D has obtained ISO certification, which indicates that it meets international quality standards. In addition, it has some typical indicators that reflect its excellent performance. For example, its Al₂O₃ content is ≥50%, and the apparent porosity is ≤2%. These indicators ensure the high - quality and reliability of TY - AZS36D.

Selection Guide for AZS Series Blocks

When selecting refractory materials, it is necessary to match different AZS series blocks according to the glass composition and operating temperature gradient. For glasses with different chemical compositions, different refractory materials may be required to ensure the best performance. For example, for glasses with a high alkali content, refractory materials with a lower Na₂O content should be selected. The following is a simple selection guide:

• For low - alkali glass, AZS series with a relatively higher Na₂O content can be considered.
• For high - alkali glass, TY - AZS36D or other low - sodium AZS series are recommended.
• According to the operating temperature gradient, materials with different heat resistance can be selected.
