Commonly used for float glass and large glass tank furnaces. Key refractory areas include the crown, breast wall, sidewall, bottom and regenerators.
High combustion temperature and strong alkali vapor corrosion make the crown, breast wall, glass contact line and throat especially important.
Often used for specialty glass, borosilicate glass and glass fiber. Electrode blocks, sidewalls, bottom blocks and flow channels require stable refractories.
Suitable for art glass, small-batch glass and specialty glass production. This section can support long-tail product keywords.
In an end-fired furnace, flame enters from one end and returns in a U-shaped path. The port area, melting tank sidewalls, bottom and regenerators are key refractory zones.
Side-fired furnaces are widely used in large tank furnaces. They require strong refractory design for crowns, breast walls, sidewalls and regenerators.
Oxy-fuel furnaces have high combustion efficiency, but temperature and alkali vapor corrosion are concentrated. Crown, breast wall, glass contact line and throat materials need higher stability.
Electric furnaces are often used for specialty glass. Refractory selection must control glass contamination and support stable operation near electrode openings.
Small glass furnaces are suitable for long-tail search terms around art glass, small-batch glass and specialty glass refractory materials.

Glass furnace melting tank sidewalls commonly use fused cast AZS brick because this area is exposed to high-temperature glass liquid and requires strong resistance to corrosion and erosion.
Glass furnace crowns operate at high temperature and carry structural load. High-quality silica brick provides good refractoriness under load and high-temperature volume stability.
AZS 33# is often used in general glass contact areas, AZS 36# is suitable for stronger corrosion zones such as sidewalls and glass contact lines, and AZS 41# is commonly used in critical areas such as throats and flow channels.
Regenerator checker bricks should be selected according to flue gas temperature, dust composition, blockage risk and heat exchange efficiency. Common options include high alumina, magnesia-alumina, magnesia and mullite checker bricks.
End-fired furnaces focus more on the end port area, regenerators and flame return zone. Side-fired furnaces are usually larger and require stronger overall refractory design for the crown, breast wall, sidewall and regenerators.
