AZS Flow Nozzle Brick

AZS flow nozzle bricks are critical functional refractories developed specifically for glass forming processes. Precision-machined from electrofused zirconia alumina (AZS) material, these components are installed at the end of feed channels to directly control molten glass flow direction and volume. Offering exceptional erosion resistance, precise channel dimensions, and stable high-temperature performance, they serve as core components ensuring both the forming quality of glass products and production efficiency。

description

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。

Core Performance Parameters (customizable):

Material options: AZS-33/36/41

Flow channel aperture tolerance: ±0.2mm

Internal surface roughness: Ra ≤ 1.6μm

Bulk density: ≥3.70–4.00 g/cm³ (increases with zirconium content)

Maximum operating temperature: 1700–1800°C
