Different areas of a glass furnace have different operating conditions.
For example:
Therefore, a single refractory material cannot meet the requirements of all furnace zones.
AZS bricks are among the most widely used refractory materials in glass melting furnaces due to their excellent resistance to molten glass corrosion.
They are commonly applied in:
AZS bricks provide:
For different glass furnace conditions, AZS bricks are available in different grades such as AZS 33, AZS 36 and AZS 41.
Silica bricks are traditionally important refractory materials for glass furnace crowns and regenerators.
Their advantages include:
Typical applications:
Silica bricks are especially suitable for areas where high-temperature stability and dimensional accuracy are required.
High alumina bricks are used in areas requiring good mechanical strength and wear resistance.
Typical applications include:
They provide:
Ceramic fiber products are mainly used for thermal insulation and energy-saving applications.
Common applications:
