Silica bricks are widely used in glass kilns

1. Kiln walls and roof: Silica bricks are commonly used to construct the walls and roof of glass kilns. These parts need to have good high temperature resistance and chemical stability to withstand the high temperature environment and chemical attack during the glass manufacturing process.

2. Kiln bottom: The kiln bottom is an important part that supports and carries the glass frit and glass liquid during the glass melting process. Silica bricks are also commonly used to construct kiln floors to ensure adequate strength and fire resistance.

3. Support and insulation structures: Inside the glass kiln, some support structures and insulation structures are usually required to support the heating and melting process of the glass frit. Silica bricks can be used to build these structures to provide good heat resistance and stability.

4. Heat exchange equipment: Heat exchange equipment is usually required in glass kilns to control the temperature and heating process in the kiln. Silica bricks may be used to construct some components of these heat exchange devices to ensure their performance and stability in high-temperature environments.

In general, silica bricks play an important role in glass kilns and are used to construct various parts and structures that require high temperature resistance and chemical stability to support and maintain the smooth progress of the glass manufacturing process.
