Description

What are Fused Cast AZS 33# Refractory Blocks?

Fused cast AZS 33# blocks made from a combination of alumina (Al2O3), zirconia (ZrO2), and silica (SiO2) are the basic quality grade of fused cast refractory blocks used in the glass furnace. AZS 33# blocks denotes the percentage of ZrO2≥32.5%. Different Companies may have different indication code. For example, SEPRO uses ER 1681 for AZS 33#, and REFEL uses 1532 for AZS 33#. With the lowest zirconium oxide content in the standard fused cast AZS product range, AZS 33# Refractory block is the essential refractory material for glass furnaces. Its chemical and physical properties make it be used in various areas of the glass furnace.

Clsaaification and properties

Fused cast AZS 33# Refractory blocks are normally classified into three quality grades:
AZS 33#PT (normal casting), AZS 33#ZWS (End Cut Casting) and AZS 33#WS (Void Free)

Fused cast AZS 33# blocks are known for their exceptional resistance to high temperatures and corrosive environments in the glass furnace and having a good ability to withstand the thermal shock during glass furnace operation.

Applications

Paving blocks

With its dense microstructure, fused cast AZS 33 blocks are resistant to glass liquids and can withstand high temperatures, ensuring the integrity and stability of the tiles. It is also highly wear-resistant and can withstand a wide range of abrasive factors for a longer service life.

Superstructures

Fused cast AZS 33 blocks ensure the stability and purity of the superstructure, reducing the generation and spread of contaminants, while having high structural strength to maintain the integrity and stability of the superstructure. The superstructure of a glass furnace may consist of different parts and shapes. Fused cast AZS 33 blocks can be customized to meet the requirements of different structures and shapes.

Feeder channel

Fused cast AZS 33 blocks have a dense microstructure, and strong erosion resistance, to ensure the stability and durability of the feeder channel, but also in the high-temperature environment to maintain stable physical and chemical properties, it is not easy to deformation or rupture, to ensure that the normal operation of the channel in high-temperature conditions.

Fused cast AZS 33 blocks have high abrasion resistance, which can resist the glass liquid's scouring and abrasion and extend the feeder channels'service life. Feeder channels may have different shapes and sizes and can be customized to meet the design requirements of other channels.
