Product Introduction
Product Details
Production method:
Low-silicon, low-sodium fused cast AZS series products are characterized by low glass phase content, good high-temperature stability, high glass phase exudate temperature, and excellent resistance to glass liquid erosion, which can significantly reduce the pollution of refractory materials to glass liquid. Its lower exudate and higher compressive strength and excellent resistance to alkali corrosion characteristics applied to the top of the glass kiln AZS big swan, pool wall corners and other parts. It is a better fused zirconium corundum product for the kiln to realize overall heat preservation, energy saving and long life. At present, it is widely used in the field of oxy-fuel glass kiln.
Casting method:
The casting methods of electrofused zirconia corundum bricks are normal casting, tilted casting, shrinkage-free casting and .
PT—Ordinary Casting
The usual casting method, the shrinkage hole of the product is located in the lower part of the casting mouth, mostly used in the upper part of the melting pool flame space parts, such as not in contact with the glass solution or erosion is not serious parts.
QX—Inclined Casting
A tilted casting method is used to create a slant in the mold, and the riser is placed at the other end for casting. The shrinkage hole of the product is placed at the lower end, which is suitable for the products with the length >60mm, mainly used for pool wall bricks.
WS—Non Shrinkage Casting
The non-shrinkage products with the shrinkage part of the casting bricks removed, mainly used in liquid holes, kiln cans, corners of the pool wall, pavement and other seriously eroded parts.
ZWS—Quasi Non Shrinkage Casting
Similar to non-shrinkage casting, basically removed the shrinkage part of the cast brick, mainly used for pool wall bricks.

Fused Cast AZS 36# Blocks are premium refractory products designed for demanding high-temperature applications. These blocks are specifically formulated to offer exceptional resistance to thermal shock, erosion, and chemical corrosion.
The "Fused Cast" process ensures a dense and homogeneous microstructure, providing superior mechanical strength and thermal stability. The blocks can withstand extreme temperatures, making them ideal for use in furnaces, kilns, and other industrial heating equipment.
AZS stands for Alumina-Zirconia-Silicate, which is the primary composition of these blocks. This unique combination of materials offers excellent resistance to acid and alkali corrosion, as well as high melting points. The 36# designation indicates the specific grade and properties tailored for particular applications.
One of the key features of Fused Cast AZS 36# Blocks is their low porosity. This characteristic minimizes the penetration of liquids and gases, thereby extending the service life of the refractory lining. Additionally, the blocks have good thermal shock resistance, allowing them to withstand rapid temperature changes without cracking or spalling.
These blocks are also known for their excellent wear resistance. In industrial environments where there is abrasion from materials or gas flow, Fused Cast AZS 36# Blocks maintain their integrity and performance over time.
In summary, Fused Cast AZS 36# Blocks are high-quality refractory products that offer exceptional thermal shock resistance, chemical corrosion resistance, and wear resistance. They are suitable for a wide range of high-temperature applications, providing reliable and long-lasting performance. Choose Fused Cast AZS 36# Blocks for your refractory needs and experience the difference in quality and durability.
