2 Types of Zirconium Corundum Brick for Sale

Sintered Zirconium Corundum Brick

Low Porosity
Goog Thermal Shock Resistance
Good Chemical Resistance
High Strength

Sintered zirconium corundum bricks refer to refractory bricks made from raw materials under a high-temperature sintering process. This product is also called ceramic bonded aluminum silicon zirconium brick. Sintered corundum zirconia bricks have high strength and strong resistance to molten glass erosion. In addition, excellent ZrO2 composition will bring smaller porosity. As a result, this product has excellent thermal shock resistance when used in kilns.

Kerui AZS Brick for Sale
Kerui AZS Brick with Good Performance

Fused Cast Zirconium Corundum Brick

Good Wear Resistance
Excellent Erosion and Corrosion Resistance
High Working Temperature
Good Thermal Shock Resistance

The main materials of fused zirconium corundum bricks will be melted in an electric arc furnace. Then we need to pour it into the molds and wait to cool and solidify. This product is what we usually call AZS bricks. When choosing high quality fused cast AZS brick for sale, we should pay more attention to the shrinkage cavity during manufacturing process. The following are several different casting methods for fused zirconium corundum bricks:

Tips: meanings of different casting methods of fused cast zirconia corundum brick:

Ordinary Casting (PT)

In the usual pouring method, the shrinkage cavity of the product is located at the lower part of the casting opening, which is mostly used in the upper structure of the melting pool. Wait for parts where erosion is not serious.

Tilt Casting (QX)

Using the inclined casting method, the shrinkage holes of the product are offset at the lower end and are mainly used as pool wall tiles.

Shrinkage-free casting (WS)

Shrinkage-free products with the shrinkage cavity part of cast acid resistant bricks removed are mainly used in severely corroded parts such as liquid caves, kiln sills, pool wall corners and pavements.

Quasi-shrinkage-free Casting (ZWS)

Similar to non-shrinkage cavity casting, the shrinkage cavity part of the cast bricks is basically removed and is mainly used as pool wall bricks.

Applications of Zirconium Corundum Bricks

Mainly Used in Glass Kiln

Due to the excellent composition, Kerui zirconium corundum brick is crucial in glass melting furnace. Especially with the development of the glass industry, customers have higher requirements for zirconium corundum bricks and high-end zirconium corundum bricks. In glass furnaces, customers often use zirconium corundum bricks in areas that are in direct contact with molten glass, such as working tank, fore-hearth, upper structure and crown, melting tank wall, clarification tank, throat, kiln weir, charging hole corner brick, bubble bricks, electrode bricks and so on.

Also Used in Other High Temperature Kilns

The performance of fused zirconium corundum bricks is excellent. This product has high strength and density. Therefore, it can ensure the compactness of the masonry structure. In addition to glass kilns, Kerui fused zirconium corundum bricks are important in key parts of other high-temperature kilns. Common applications include ladle linings, rolling steel heating furnace slides, tops, burners, thermocouples, peepholes and melter bottoms and backings, glass melting furnaces, fiberglass furnaces, metallurgical furnaces, chemical furnaces, etc. You can also see more details on Kerui Facebook.
