Precautions for using fused zirconium corundum bricks

Fused zirconium corundum brick is a high-temperature refractory material commonly used in high-temperature industrial equipment, such as metallurgical furnaces, glass kilns, ceramic kilns, etc. When using fused zirconium corundum bricks, you need to pay attention to the following matters:

1. Pre-installation inspection: Before installation, the fused zirconium corundum bricks need to be inspected to ensure that the bricks have no obvious damage or defects to avoid problems during use.

2. Storage environment: The storage environment of fused zirconium corundum bricks should be kept dry, ventilated, and avoid contact with water to prevent the bricks from absorbing moisture and affecting their performance.

3. Installation operation: When installing fused zirconium corundum bricks, the operation should be carried out in accordance with relevant specifications and requirements. First clean the brick bed to make sure it is smooth and free of impurities. Then fix the bricks in the correct order and manner to avoid problems such as misalignment of bricks or hollowing of the blocks.

4. Operating temperature: The operating temperature of fused zirconium corundum bricks is usually above 1500°C. Therefore, it is necessary to ensure that the equipment does not exceed the operating temperature of the bricks during normal operation to avoid melting or embrittlement of the bricks.

5. Restrictions on use conditions: Fused zirconium corundum bricks have weak resistance to acidic and alkaline substances and thermal shock. Therefore, during use, care should be taken to avoid long-term exposure to acidic and alkaline media and to avoid temperature changes. Thermal shock problems caused by excessive size.

6. Regular inspection and maintenance: Regularly check the use of fused zirconium corundum bricks, and repair or replace the bricks in time to ensure the normal operation of the equipment and extend the service life of the bricks.

In general, when using fused zirconium corundum bricks, attention must be paid to maintaining the integrity of the bricks and the stability of the use environment to ensure their fire resistance and service life. In addition, relevant installation and usage regulations must also be followed to ensure the safety and normal operation of the equipment.
