Indian Glass Industry Monofrax S-3 S-4 S-5 AZS Brick with Refractoriness of 1770°-2000°

Description of Monofrax S-3 S-4 S-5 AZS brick

Monofrax S-3 S-4 S-5 AZS brick, the full name of which is Electrically Fused Alumina-Zirconia-Silicate Refractory Brick, are high-performance, high-temperature and corrosion-resistant refractory materials. They are widely used in glass melting furnaces, ceramic industries, and other fields that need to withstand extreme high temperatures and chemical corrosion environments. 

Monofrax S-3 S-4 S-5 AZS brick are mainly composed of alumina (Al2O3), zirconium oxide (ZrO2), and silicate (SiO2). According to the different zirconium oxide content, Monofrax S-3 S-4 S-5 AZS brick 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 Monofrax S-3 S-4 S-5 AZS brick 

Fused refractory block AZS33 S-3 AZS brick 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 S-4 AZS brick 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 S-3 AZS brick 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 Monofrax S-3 S-4 S-5 AZS brick 

High temperature resistance: Due to the special composition, Monofrax S-3 S-4 S-5 AZS brick 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.

Producing pcessing of Monofrax S-3 S-4 S-5 AZS brick 

1. Sand mold making:

The sand mold is made of silica sand and water glass as a binding agent according to the shape of Monofrax S-3 S-4 S-5 AZS brick.

2. Raw material processing and proportioning by computer:

Raw materials such as alumina powder, zircon sand and desiliconized zirconium and other raw materials shall be put into storage for use or sent to raw materials for pretreatment after acceptance. 

3. Melting process:

Mainly in accordance with the requirements of the production plan, the matched fused zirconium corundum raw materials are added to the automatically controlled electric arc furnace and melted under the best conditions.

4. Casting process:

Pour the molten material into a specially designed product mold. T

5. Heat preservation and annealing process:

The cast bricks are slowly cooled, so that the crystals of the prepared fused zirconia corundum bricks grow and form the best structure. 

6. Demoulding process:

The annealed fused cast zirconium corundum bricks are taken out of the cavity using equipment for product inspection.

7. Machining rocessing:

Check the appearance defects, carry out high-precision grinding according to the requirements of users to ensure the size and surface accuracy of the bricks.

8. Pre-assembling and packing:

After Machining processing, it is pre-assembled to ensure that the product size is packaged and shipped.

Casting method of fused cast AZS bricks

Monofrax S-3 S-4 S-5 AZS brick are made by completely melting the raw materials and casting it in a casting mold, which is cooled and solidified. The shrinkage caused by the volume shrinkage of this product during condensation is a matter of special attention when using it. The casting methods of fused zirconium corundum bricks are ordinary casting (PT), inclined casting (QX), non-shrinkage casting (WS) and quasi-shrinkless casting (ZWS).
