1.Descriptions of Fused
Cast AZS Bricks
Our fused
AZS blocks mainly inclue model
AZS-33#, AZS-36#, and
AZS-41#. the different
models applicated in different parts of furnaces.
AZS brick 33#, a normal
refractory material, with the features of very good melting glass resisting, which seldom produces
stone or other faults, and has little possibility to produce bubbles, widely used in glass Industrial furnace.
AZS brick 36# has more free
baddeleyite crystals in chain structure and less vitreous phase, which further improves the corrosion
resistibility and reduces the potential defects in glass, so it is recommended to be used in sections where glass flow is faster and
temperature is higher, such as melter sidewall, paving, doghouse, etc.
AZS brick 41# has the most
free baddeleyite crystals among the fused cast AZS families, which are evenly distgributed within the block. Its corrosion resistibility is the best and thus it is usually recommended to be used
in the most demanding positions to balance the furnace life.
2.Advantages of
Fused Cast AZS Bricks
1. Best erosion
resistance;
2. Not easy to generate
small bubbles;
3. Good thermal shock
resistance;
4. Stable performance
for furnaces;
5. Suitable for
structure;
6. Long service
time.
