glass melting furnace design
Fused Cast AZS Block as an important role used in glass melting
furnace design is made of pure alumina powder and zircon sand and
is composed of three main chemical components of Al2O3, ZrO2 and
SiO2. Fused Cast AZS Block is manufactured through casting
technology in RS Professional Factory.
AZS Blocks, Alumina-Zirconia-Silica (AZS) refractories, belong to
sintered ZrO2_Al2O3_SiO2 products family along with Zircon Mullite,
Bonded AZS, Zirconia Corundum, and Rebonded Fused Mullite bricks.
Sintered ZrO2-Al2O3_SiO2 products such as AZS have good resistance
to alkali vapor and thermal shock. Mainly used in glass melting
furnace designs, they can withstand aggressive conditions in
contact with molten glass.
Fused Cast AZS Refractory bricks products of AZS series of
oxidation are made of qualified raw materials by using specially
designed electric arch furnace and undergoing the casting process
through long-arc melting furnace and oxidation. This kind of
casting process hardly suffers any carbon pollution from the
electrode.
Properties Of Fused Cast AZS Block
Dense micro structure
Strong resistance for high temperature and glass liquid
Good thermal shock resistance
High compression resistance
Wear and slag erosion resistance
Shapes & Sizes Of Fused Cast AZS Block

Manufacturing Process of AZS Block
There are four steps for manufacturing process of AZS Block
including melting of raw materials, casting, cooling and cutting.
Prefer proportions of 1:1 zircon sand and industrial alumina powder
and add few volume of NaZO, B20 agent of fusion after mix perfectly
through smelting and pouring into mould at high temperature of
1900~2000℃ resulting the fused cast brick contained 33% ZrO2
content. On the base, adopt part of desilicication zircon sand as
the raw material to make the fused cast brick with 36%~41% ZrO2
content.
If the casting speed is too fast and the temperature is too high,
the air in the mold will not be exhausted and the bottom of the
mold will be broken, which will waste the casting time. So it is
very important to control the casting temperature and speed.
The quality of AZS Block is subjected by the quality of raw
materials and manufacturing technology. Rongsheng Refractory as a
professional fused cast AZS block manufacturer can provide
customers with high quality AZS Block at low price based on our
professional engineers, advanced technology and equipment.
Due to the application of such casting technology and high-purity
raw materials, AZS Block of oxidated electrocast zirconia-alumina
products are possessed of special and high quality of erosion
resistance of glass liquids. In addition, it has the minimal
pollution to the glass.
AZS Block-33
AZS Block-33 are excellent in preventing the pollution of glass liquids. The
possibility of causing glass stones, bubbles and basic glass phase
precipitation is quite slim. It can be applied to the upper
structure of melting pool, the tank wall corner tiles,paving bricks
and other approaches as well.
AZS Block-36
AZS Block-36 are the standard Fused Cast AZS Refractory bricks brick which
boasts of the quality of particularly high corrosion resistance of
glass liquids and low pollution. More than that, it has a balanced
performance in the above two aspects. It can be applied to the
direct access of glass melting furnace design and glass liquids,
such as melting tank wall corner tiles, paving bricks and charging
door.
AZS Block-41
AZS Block-41 are the best oxidated zircon corundum brick which
possesses the quality of highest corrosion resistance of glass
liquids and excellent low pollution of glass liquids. It can be
applied to the locations of glass melting furnace design which
requires particularly high corrosion endurance, such as full-fused
furnace, liquid pumps, furnace ridge, bubbling brick and bricks of
charging door corners.
Besides, the fused cast AZS Blocks can be devied into different
types according its casting techniques, PT [normal casting], QX
[tilt casting ] , ZWS [reinforced casting ] and WS [void-free
casting].
WS while casting, the casting size is bigger than that is required.
Most of the voids concentrate in the header which is subsequently
cut off with a diamond saw, and then the block in required size is
left, most used in side wall and flow.
PT The brick made by normal casting has normal shrinkage void; it is
often used in the upper structure of furnace and the interface
parts which touch molten glass.
ZWS while casting, the casting size is bigger than it is required.
Most of the voids concentrate in the header which is subsequently
cut off with a diamond saw, and then the block in required size is
left, most used in side wall.
QX by tilt casting, shrinkage voids focus on one side, while the
other side is dense. This kind of bricks are usual sabity is
located towards the bottom, and of the block that used for
sidewalls.
