Product Description
Description of AZS-33/AZS-36/AZS-41
AZS-33/AZS-36/AZS-41 as an important role used in Glass Furnace is
made of pure alumina powder and zircon sand and is composed of
three main chemical components of Al2O3, ZrO2 and SiO2,most widely
used materials both in glass contact and superstructure of glass
melting furnaces. Fused cast zirconia corundum block for Glass
furnace are made of high pure material, fired at high temperature
by advanced technology, with the advantages of high strength, high
compression resistance, good thermal shock resistance, good
performance in high temperature, good thermal
conductivity,excelerosion resistance and used for linings of
furnace in glass industries
The difference and application of different grades of
AZS-33/AZS-36/AZS-41
ER1681-Fused Zirconia Corundum Brick AZS33#:
The dense microstructure of AZS33# zirconium corundum bricks makes the bricks have good resistance to glass liquid corrosion, and it is not easy to produce stones or other defects in the glass furnace. It is the most widely used product in glass kilns, and is mainly used for the upper structure of the melting pool, the pool wall and paving bricks of the working pool, and the material channel.
AZS33 is the most widely used product in the cast AZS series, and has excellent performance in preventing contamination of glass liquid. It is widely used in the wall, bottom, upper structure and feeding channel of the glass furnace.
ER1691- Fused Zirconia Corundum Brick AZS36#:
In addition to having the same co-crystal structure as AZS33# fused zirconia corundum brick, 36# Fused cast AZS Brick has more chain-like zirconia crystals and lower glass phase content, so 36# fused zirconia corundum brick is corrosion resistant The performance is further enhanced, so it is suitable for areas where the flow rate of the molten glass is faster or the temperature is higher.
AZS36 s is a product with excellent performance in the cast AZS series. It has high resistance to glass erosion and low pollution. It is usually used in key parts such as the pool wall near the hot spot of the glass melting pool.
ER1711-Fused Zirconia Corundum Brick AZS41#:
AZS41# fused zirconia corundum bricks not only have the eutectic of silica and alumina, but also contain more uniformly distributed zirconia crystals. In the zirconia corundum brick system, its corrosion resistance is good. Therefore, the key parts of the glass furnace are selected so that the life of these parts is lower than other parts.
AZS41 is the product with the highest performance in the fusion cast AZS series. It has extremely high resistance to glass liquid corrosion and extremely high glass phase exudation temperature, and it has very low pollution to glass liquid. It is widely used in key parts of the hot spot of the glass furnace, such as the wall of the glass furnace, the corner of the feed opening, the liquid hole, the sill, the bubbling at the bottom of the tank, and the all-electric furnace.
Features of AZS-33/AZS-36/AZS-41:
1. Raw material is corundum and baddeleyite eutecticum,high
compression strength
2.Top high-temperature capablility,excellent thermal stability.
3.Strong resistant erosion stability to the glass liquid

Casting method of AZS-33/AZS-36/AZS-41 :
Electrocast zirconia corundum block is made by completely melting the raw materials and casting it in a casting mold, which is cooled and solidified. The shrinkage caused by the volume shrinkage of this product during condensation is a matter of special attention when using it. The casting methods of fused zirconium corundum bricks are ordinary casting (PT), inclined casting (QX), non-shrinkage casting (WS) and quasi-shrinkless casting (ZWS)
Usage of AZS-33/AZS-36/AZS-41
AZS-33/AZS-36/AZS-41 is widely used in glass melting furnace because the fused zirconium corundum brick is an important refractory material variety in modern glass melting furnaces. It is currently produced in a large amount in the world. It is a widely used refractory product. It has good resistance to glass erosion and resistance to rapid cooling and heat. The heat load performance is applied to all important parts of the furnace.
PT: The usual pouring method, the shrinkage hole of the product is
located in the lower part of the casting mouth, and it is mostly
used for the upper structure of the melting pool.
QX: The oblique casting method is adopted, and the shrinkage hole of
the product is offset to the lower end, which is mainly used as a
pool wall brick.
WS: Non-shrinkage casting, the non-shrinkage product of the shrinkage
hole part of the cast brick is mainly used, such as the liquid
erosion hole, the kiln sill, the corner of the pool wall, the
paving surface, etc.
ZWS: Quasi-free shrinkage casting, mainly used as pool wall bricks,
basically removing the shrinkage of the cast bricks, mainly used as
pool wall bricks.
