Fused Cast AZS bricks

Introduction:
AZS block is also called fused zirconia corundum brick which contains Al2O3-ZrO2-SiO2. The fused cast AZS block is made of pure aluminum powder and zircon sand (consisting of 65% zirconia and 34% SiO2). After the aluminum powder and zircon sand are melted in an electric furnace, they are cast into various molds and cooled down to become white solids. Since the content of zirconia is between 33% and 41%, the fused cast AZS blocks are divided into three types: AZS-33#, AZS-36# and AZS-41#.

Features:
t micro-structure.
erosion resistance.
thermal shock resistance.
compression resistance.

Application:
It is mainly used in glass industry.
