AZS refractory brick is applied to glass furnace or frit furnace. After complete melt, Cast in the mould with materials, produced by cooling and curdle. Especially Notice is in the condensation course, due to volume constriction become cavities. Its code is AZS-33NC, AZS-33CF, AZS-41CF in China.

The AZS's cast method is Normal Cavity, Oriented Cavity, Cavity Free and

Reduced Cavity. Different cast methods of AZS product are suitable for

Different glass kiln part's requirement.
