Fused cast AZS brick is one kind of refractory brick that is made of pure alumina powder and zircon sand, the main composition of fused cast AZS brick is Al2O3, ZrO2 and SiO2 that directly reflects the meaning of AZS. This brick is produced by adopting casting technology method which is by melting the raw material in the electric furnace, then casting into various molds and cooling themselves down to become solid. As all we know, Al2O3 has the special property of a relatively high thermal conductivity, ZrO2 has the property of superior mechanical, thermal, electrical, chemical and optical properties. When they are bonded with special method, the good performance is revealed to fused cast AZS brick.
Both the chemical composition and the special casting method lead to the excellent performance and property of fused cast AZS brick. The most prominent feature is dense structure which results in the low potential for stoning, blistering and exudation of the matrix glass. What is more, when using in glass furnace, fused cast AZS brick has high corrosion resistance to glass liquid, excellent minimal contamination property
With the performance，fused cast AZS brick is mainly applied to all the melting pool where directly gets in touch with the glass liquid such sidewall, paving of working end, doghouse bricks, super structure, fore hearth, throat, bubbling brick, corner brick, etc.
According to the different content of ZrO2 from 33%-41%, fused cast AZS brick can be divided into three types AZS—33#,AZS—36# and AZS—41#, in addition, the casting technology has different grade, and different type of fused cast AZS brick can adopt different grade casting technology, so different types of fused cast AZS brick using different production technology has different characteristics, applications are also different.
