Customized AZS Spouts for Pharmaceutical Glass Tube Production Solutions in White
Customized AZS spouts for phamaceutical glass tube making
Description of special shaped fused cast AZS
Fused cast AZS, the full name of which is Electrically Fused Alumina-Zirconia-Silicate Refractory Brick, are high-performance, high-temperature and corrosion-resistant refractory materials. T
Fused cast AZS are mainly composed of alumina (Al2O3), zirconium oxide (ZrO2), and silicate (SiO2). According to the different zirconium oxide content, Fused cast AZS are usually divided into several grades, such as AZS-33#, AZS-41#, and AZS-36#, and the numbers represent the mass percentage of zirconium oxide.

Applications of Fused cast AZS
Fused refractory block AZS33 products are suitable for the upper structure of the melting pool, the pool wall bricks and paving bricks of the working pool and the material channel.
Fused refractory block AZS36 are suitable for parts in the glass melting furnace that are in direct contact with molten glass, such as melting pool wall bricks, paving bricks, and charging ports.
Fused refractory block AZS41 are suitable for parts in glass furnaces that require particularly high corrosion resistance, such as all-electric melting furnaces, liquid flow holes, kiln sills, bubbling bricks, and bricks at the corners of charging ports.
Features of Fused cast AZS
High temperature resistance: Due to the special composition, AZS refractory can maintain structural stability in high temperature environments up to 1700°C or above.
Erosion resistance: It shows strong corrosion resistance in high-temperature molten glass or other corrosive media, especially resistance to alkaline substances.
Thermal stability: Good thermal expansion coefficient matching and thermal shock stability reduce cracks and peeling caused by rapid temperature changes.
Mechanical strength: Even under long-term high-temperature operation, it can maintain high mechanical strength to ensure the stable operation of the equipment.
