Profile Of Fused Cast AZS Block

What's Fused Cast ?
The term Fused Cast refers to a manufacturing process in which the ceramic bonding is obtained by the solidification of a mixture which has been melted in an electric furnace and cast in liquid state into molds.
What does AZS mean?
Fused Cast AZS block is also called electro Zircon corundum brick, which is abbreviated as AZS because it contains Al2O3-ZrO2-SiO2. Acording to the different content of Zirconia from 33%-41%, fused cast AZS blocks can be divided into three types AZS—33#,AZS—36# and AZS—41#. Fused cast AZS block is made from pure alumina powder and Zircon sand (composed of 65% zirconia and 34% SiO2). After Alumina powder and zircon sand melting in electric furnace, they are cast into various molds and cool themselves down to become white solid.
Where is Fused cast AZS used?
Fused cast AZS refractory materials are among the best, thus being widely used in the structure of glass melting furnaces. And different types are used in different parts of glass melting furnaces as each type of fused cast AZS has a different corrosion resistance. To give you only one example, the fused cast AZS refractory class containing 36% ZrO2 has an excellent resistance to corrosion. This makes it a very good choice for the glass contact parts of the melters. It is also very effective in paving blocks and side walls. The 17% ZrO2 Super Low Exudation is very good because it allows eliminating the vitreous phase exudation. The result is a higher quality of the glass. 
As you can see, each class of materials has its characteristics that make it better for certain processes and terrible for others. Only a team of skilled technicians can thoroughly assess all parameters and recommend the perfect solution for each process.
