Fused cast AZS major include model AZS-33; AZS-36; AZS-41. the different model applicated in different parts of furnaces.
AZS block 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 block 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 block 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.Certificate of used Cast AZS block 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
Our bottom block is made from high quality raw material, processed by fine batching, forming, drying and firing process. After that the block will be matched by cutting, grinding, milling and drilling to assure of the accurate sizes. The physical and chemical properties of our bottom block are excellent, the appearance and size are accurate, especially the anti hydrogen diffusion ability and anti alkali erosion ability of the product are remarkable. This block can be used in the whole bottom of floating glass tin bath.
