How to solve the problem of glass defects caused by erosion of AZS refractory materials?

To solve the problem of glass defects caused by erosion of AZS refractory materials, the following measures should be taken:

1. Optimize the production process of AZS refractory materials:

by improving the raw material formula, increasing the melting temperature and uniformity, reducing the content of pores and impurity elements, thereby improving the density and chemical stability of AZS blocks.

2.Select suitable refractory materials:

According to the glass type and furnace conditions, select suitable AZS refractory materials, such as adjusting the ratio of ZrO2, Al2O3 and SiO2 to improve the erosion resistance of refractory materials.

3.Strengthen furnace management:

regularly check the furnace working conditions to ensure the stability of the melting system and avoid excessive temperature fluctuations. At the same time, reasonably control the flow speed and direction of the glass liquid to reduce the scouring and erosion of the refractory materials.

4. Use coating protection:

Applying an anti-erosion coating on the surface of AZS refractory materials can effectively reduce its direct contact with glass liquid, thereby extending its service life and reducing the occurrence of defects.

5. Regular maintenance and replacement:

Timely maintenance and replacement of severely eroded AZS refractory materials to prevent further detachment and mixing into the glass liquid.

6. Strengthen defect analysis and tracking:

By establishing a complete defect analysis system, chemical composition and microstructure analysis of glass defects are carried out, the source of defects is traced, and targeted measures are taken to improve them.
