How to avoid peeling of refractory bricks in kilns

The application of refractory bricks in kilns is quite extensive, but a common problem encountered during the use of this brick is peeling. Once the brick peels off, it not only affects the normal operation of the kiln, but also may cause safety issues. So, how can we effectively avoid peeling? This article will reveal the solution to this problem for you.

1. Choose high-quality bricks

The high temperature environment of kilns places high demands on the performance of refractory bricks. When selecting, it should be ensured that it has excellent high-temperature resistance, corrosion resistance, and mechanical strength. At the same time, it is necessary to choose a legitimate brand that has undergone quality certification to avoid potential peeling hazards caused by material quality issues.

2. Reasonable design and construction

In the design and construction process of the kiln, factors such as the stress and thermal expansion coefficient of the bricks should be fully considered to ensure their stability at high temperatures. In addition, anchor components, support structures, etc. should be reasonably set to increase the adhesion of bricks and prevent them from peeling off.

3. Strengthen daily maintenance and upkeep

During the operation of the kiln, the appearance, thickness, and integrity of refractory bricks should be regularly inspected, and potential peeling hazards should be discovered and dealt with in a timely manner. At the same time, regular baking maintenance should be carried out on the kiln to maintain the stability of the bricks at high temperatures.

4. Control temperature and pressure fluctuations during operation

During the operation of the kiln, temperature and pressure fluctuations should be strictly controlled according to the process requirements to avoid damage to the refractory bricks caused by excessive temperature or pressure fluctuations.

5. Adopting advanced monitoring technology

By installing temperature sensors, infrared imaging devices, and other monitoring devices, real-time monitoring of temperature changes and surface conditions of bricks can be carried out, and abnormal situations can be detected in a timely manner and corresponding measures can be taken.

In summary, avoiding the peeling of refractory bricks in kilns requires multiple approaches. By selecting high-quality materials, designing and constructing reasonably, strengthening daily maintenance and upkeep, controlling operating temperature and pressure fluctuations, and adopting advanced monitoring technology, the risk of peeling can be effectively reduced, ensuring the safe and stable operation of the kiln. Meanwhile, for bricks that have already peeled off, timely repair measures should be taken to avoid the problem from escalating.
