Description of Fused cast AZS Brick Zirconia Corundum brick

Fused cast AZS Brick Zirconia Corundum brick is an important role used in Glass Furnace is made of pure alumina powder and zircon sand and is composed of three main chemical components of Al2O3, ZrO2 and SiO2,most widely used materials both in glass contact and superstructure of glass melting furnaces. Fused cast zirconia corundum block for Glass furnace are made of high pure material, fired at high temperature by advanced technology, with the advantages of high strength, high compression resistance, good thermal shock resistance, good performance in high temperature, good thermal conductivity,excelerosion resistance and used for linings of furnace in glass industries

The difference and application of different grades of Fused cast AZS Brick Zirconia Corundum brick

ER1681-Fused Zirconia Corundum Brick AZS33#:

The dense microstructure of AZS33# zirconium corundum bricks makes the bricks have good resistance to glass liquid corrosion, and it is not easy to produce stones or other defects in the glass furnace. It is the most widely used product in glass kilns, and is mainly used for the upper structure of the melting pool, the pool wall and paving bricks of the working pool, and the material channel.

AZS33 is the most widely used product in the cast AZS series, and has excellent performance in preventing contamination of glass liquid. It is widely used in the wall, bottom, upper structure and feeding channel of the glass furnace.

ER1691- Fused Zirconia Corundum Brick AZS36#:

In addition to having the same co-crystal structure as AZS33# fused zirconia corundum brick, 36# Fused cast AZS Brick has more chain-like zirconia crystals and lower glass phase content, so 36# fused zirconia corundum brick is corrosion resistant The performance is further enhanced, so it is suitable for areas where the flow rate of the molten glass is faster or the temperature is higher.

AZS36 s is a product with excellent performance in the cast AZS series. It has high resistance to glass erosion and low pollution. It is usually used in key parts such as the pool wall near the hot spot of the glass melting pool.

ER1711-Fused Zirconia Corundum Brick AZS41#:

AZS41# fused zirconia corundum bricks not only have the eutectic of silica and alumina, but also contain more uniformly distributed zirconia crystals. In the zirconia corundum brick system, its corrosion resistance is good. Therefore, the key parts of the glass furnace are selected so that the life of these parts is lower than other parts.

AZS41 is the product with the highest performance in the fusion cast AZS series. It has extremely high resistance to glass liquid corrosion and extremely high glass phase exudation temperature, and it has very low pollution to glass liquid. It is widely used in key parts of the hot spot of the glass furnace, such as the wall of the glass furnace, the corner of the feed opening, the liquid hole, the sill, the bubbling at the bottom of the tank, and the all-electric furnace.

Features of Fused cast AZS Brick Zirconia Corundum brick  : 

1. Raw material is corundum and baddeleyite eutecticum,high compression strength

2.Top high-temperature capablility,excellent thermal stability.

3.Strong resistant erosion stability to the glass liquid.
