1.fused cast AZS brick description:
Fused AZS block major include model AZS-33; AZS-36; AZS-41. the different model 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. And it is widely used in glass Indaustrial furnace.
AZS brick 36#, has more free baddeleyite crystals in chain structure and less vitreous phase, which further improve the corrosion resistibility and reduce 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.fused cast AZS brick advantages:
1.Best erosion resistance
2. not easy to generate smal bubble
3. good thermal shock resistance
4. stable performance for furnace
5. suitable for structure
6. long service time
