AZS Brick High Grade Fused Cast Refractory Bricks With High Quality
And Best Use In Glass Furnace
AZS Brick Description:
AZS Brick, also called Fused Cast Alumina-Zirconia-Silica
Refractory Brick for sale in Manufacturer RS, belongs to a kind of
high-grade fused cast refractory bricks with high quality and best
uses in glass furnace. Fused Cast AZS Brick can directly touch with
high temperature molten metal and slag.
AZS Brick, solid with white color, is made of pure alumina powder
and zircon sand containing about 65% ZrO2 and 34% SiO2 content that
are injected to be mold after being melt in the electric melting
furnace. Its petrographic structure is composed of eutectoid and
glass phase from corundum and zirconium inclined stone.
AZS Brick actually is Fused Cast Alumina-Zirconia-Silica Refractory
Brick that including three main chemical components of Al2O3, ZrO2
and SiO2. Fused cast AZS Brick is manufactured under the high
temperature of 1900~2000 degree through melting and molding
Properties of AZS Refractory Brick:
- High Temperature and Erosion Resistance
- High Compactness Property
- Good Mechanical Property and Wear Resistance
Application of Fused Cast AZS Alumina Fire Brick:
- AZS brick can be used as the materials for resisting molten metal
and melt slag.
- AZS brick is the key materials to be used for the important
position in glass furnace.
- Fused Cast AZS Refractory Bricks also can be used in the metal
smelting furnace and container for resisting slag erosion.
- AZS Brick should not be used in the position with vagaries of
temperature among 900~1160 degree.

Production Process of AZS Brick for Glass Furnace:
- Burdening: Mix high purity fused alumina zirconia bricks raw
materials with excellent properties after weighting and take good
advantage of the properties of all kinds of raw materials.
- Fusing: Add burdening mixing materials into the self-controlled
electric-arc furnace for fusing under the best condition.
- Pouring: Pouring the fused alumina zirconia molten materials into
the special designed products mould.
- Annealing: Cooling the fused alumina corundum bricks slowly and
make the bricks’ crystal grow to be the best structure.
- Surface working: Use precision processing equipment to manufacture
AZS Bricks according with the required precise sizes.
- Inspection: Inspect the appearance of each brick according to the
contract forms strictly.
- Physical and chemical analysis: Make a physical and chemical
analysis on fused alumina zirconia bricks according to the
requirements of contract.
- Preassembling: Preassembling the bricks for key position according
to the drawing.
- Packaging: Package well all the finished bricks.
Test of Fused Cast AZS Brick:
- AZS Brick common specifications of refractoriness, reheating linear
shrinkage and expansion, refractoriness under load, true density,
cold crushing strength, apparent porosity, thermal shock resistance
and specific resistance that generally are provided by professional
fused cast AZS bricks manufacturer for user department. It is not
enough to just learn about the properties of AZS brick, you need to
learn more detailed about the reaction situation of glass liquid
and furnace gas erosion.
- Put AZS Bricks into glass furnace and inspect the performance. But
there is risk for this test that if the AZS bricks happen to damage
and then there will be more loss from operating period and dates.
It is necessary to do some test on the application property, such
as:
- Compare the erosion situation and estimate the service life of AZS
Bricks.
- Inspect the effect of fused bricks.
- Evaluate the quality of fused cast AZS Bricks, and conduct to
improve the manufacturing of AZS Bricks.
- Inspect if the AZS bricks are suitable for the melting and molding
in the glass furnace.
