High Quality Dense Fused Cast AZS Refractory Blocks for Glass Furnace
The Description:
Fused zirconium corundum bricks belong to the Al2O3-ZrO2-SiO2 system (referred to as AZS bricks). According to the content of ZrO2, it is divided into three levels, and the corresponding brands are: AZS-33(containing ZrOz 33%> (see Figure 10-3>), AZS-36 (containing ZrO2 36%), AZS-4l (containing Zr02 41%).
