AZS refractory application

AZS33# fused cast zirconia corundum bricks have a dense microstructure, resulting in excellent resistance to glass melt corrosion and preventing the formation of stones or other defects in glass furnaces. It is the most widely used product in glass furnaces, mainly suitable for the upper structure of the melting tank, the tank walls and paving bricks of the working tank, and the forehearth. AZS33 is the most widely used product in the fused cast AZS series, offering superior performance in preventing glass melt contamination. It is widely used in the tank walls, tank bottom, upper structure, and forehearth of glass furnaces.

AZS36# fused cast zirconia corundum bricks, in addition to having the same eutectic crystals as AZS33#, contain more chain-like zirconia crystals and have a lower glass phase content. Therefore, the corrosion resistance of AZS36# fused cast zirconia corundum bricks is further enhanced, making them suitable for areas with faster glass melt flow or higher temperatures. AZS36 is a high-performance product in the fused cast AZS series, possessing high resistance to glass melt corrosion and low contamination characteristics. It is typically used in critical areas such as the tank walls near the hot spots of glass melting furnaces.

AZS41# fused cast zirconia corundum bricks, in addition to containing eutectic crystals of silicon dioxide and aluminum oxide, also contain more evenly distributed zirconia crystals. In the zirconia corundum brick system, it has the best corrosion resistance. Therefore, it is selected for critical parts of glass furnaces to ensure that the lifespan of these parts is balanced with other parts. AZS41 is the highest-performing product in the fused cast AZS series, possessing extremely high resistance to glass melt corrosion and a very high glass phase exudation temperature, resulting in extremely low contamination of the glass melt. It is widely used in critical areas of glass furnaces such as the tank walls at hot spots, doghouse corners, throats, furnace sills, tank bottom bubbling areas, and all-electric melting furnaces.
