AZS flow nozzle bricks are optimized based on the ternary system of alumina-zirconia-silica. Through specialized electric-fused casting and precision machining techniques, they achieve the following characteristics:
Exceptional erosion resistance: The high zirconia content (ZrO₂ 33%-41%) structure effectively withstands erosion and chemical attack from high-velocity glass flow, making it particularly suitable for reactive media such as high-alkali glass and borosilicate glass。
Precision Flow Channel Structure: CNC machining ensures dimensional accuracy (tolerance ±0.2mm) and surface finish of flow channels, guaranteeing stable laminar flow of molten glass。
Low contamination: Minimal glass phase exudation prevents defects like stone formation and streaking, making it ideal for high-end products like optical and electronic glass。
Superior thermal shock resistance: Unique structural design and material formulation enable the product to withstand frequent temperature fluctuations in the forming zone。
