Introduction to fused zirconium corundum brick(AZS Bricks):
Electric fused zirconium corundum bricks, also called Fused AZS 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%.

AZS-33 Bricks
AZS-33 bricks has good corrosion resistance to liquid glass, is not easy to produce stones or other defects, and has low possibility of producing small bubbles. Therefore, AZS-33 bricks are widely used in glass kilns, mainly applicable to the upper structure of the melting pool, the pool wall bricks and paving bricks of the working pool, and the material channel.
AZS-36 Bricks
In addition to having the same eutectic body as the AZS33 bricks, AZS36 brick is suitable for areas with high liquid glass flow rate and high temperature, such as melting pool wall bricks, paving bricks, charging port bricks, etc., because of the increase of more interlocking zirconia crystals and the decrease of glass phase content.
AZS-41 Bricks
AZS41 bricks contains more uniformly distributed zirconia crystals besides the eutectic of silicon oxide and aluminum oxide. In the zirconia corundum brick system, its corrosion resistance is the best. Therefore, the key parts of the glass furnace were selected to balance the life of these parts with that of other parts.
AZS41 ist das exzellenteste Produkt der Schmelz- und Gießerei-AZS-Serie, mit extrem hoher Korrosionsbeständigkeit gegenüber flüssigem Glas und extrem hoher Sickertemperatur der Glasphase sowie extrem geringer Verschmutzung des flüssigen Glases. Es ist weit verbreitet in Schlüsselteilen wie Wannenwand, Einlaufecke, Fließloch, Ofenfirst, Wannenbodenblasen und allen elektrischen Schmelzöfen an der heißen Stelle des Glasofens verwendet.
AZS-36S Bricks
Die silizium- und natriumarmen AZS-Schmelz- und Gusssteine zeichnen sich durch einen geringen Glasphasengehalt, eine hohe Sickertemperatur der Glasphase, eine gute Hochtemperaturstabilität und eine hohe Korrosionsbeständigkeit gegenüber flüssigem Glas aus. Sie sind Schmelz- und Guss-Feuerfestmaterial für die Realisierung der gesamten Wärmedämmung, Energieeinsparung und lange Lebensdauer des Ofens.
