Fused Cast 41 ＃ AZS Block ( RH-AZS41)
Fused AZS bricks also called Electric fused zirconium corundum bricks, are arranged according to the three chemical components in the phase diagram of Al2O3-ZrO2-SiO2. Among them, 33, 36 and 41 are named according to the content of Al2O3. For example, AZS33 refers to the fused zirconium corundum brick with an alumina content of 33%.
Outstanding low contamination to molten glass. It is applicable to the parts of glass furnace that require high corrosion resistance, such as all electric melting furnace, forehearth, weir, bubbling block, corner block of doghouse, etc.
