Product Description
monofrax s-3 s-4 s-5 AZS bricks Fused cast zirconia corundum bricks
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.

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 monofrax s-3
s-4 s-5 Fused cast zirconia corundum bricks
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# 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 monofrax s-3 s-4 s-5 Fused cast zirconia corundum
bricks:
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 monofrax s-3 s-4 s-5 Fused cast zirconia corundum
bricks :
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 monofrax s-3 s-4 s-5 Fused cast zirconia corundum bricks
Fused Cast zirconia corundum are 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.
