Clay bricks are the most basic refractory material in industrial kilns. For buyers, mastering the core selection criteria can effectively balance cost and performance.
1.Core elements of clay bricks
First, the clay brick material is fundamental to its performance. It is mainly made of 50% soft clay and 50% hard clay. Therefore, the content of alumina (Al₂O₃) in the raw materials directly determines the refractoriness and load softening temperature of the brick.
Secondly, there are different types of these bricks. Ordinary clay refractory bricks, high-alumina clay fire bricks, and low-porosity clay bricks exhibit different performance characteristics in key indicators such as slag erosion resistance and thermal shock stability.
Because of these differences in performance, these bricks can vary significantly in price. Generally, the higher the alumina content and the better the performance, the higher the price. Therefore, buyers need to weigh their budget and performance requirements.
2.Make a choice based on your needs
No refractory brick is a “one-size-fits-all” material; it needs to be precisely matched to the working conditions.
Therefore, it is essential to first clarify the detailed operating conditions of the kiln or thermal equipment.
For example, for ordinary industrial kilns operating at temperatures below 1300℃, standard clay bricks may be the most cost-effective option.
However, if there is highly alkaline slag in the kiln, you may need to consider magnesia-chrome refractory bricks, which have better slag resistance, instead of ordinary clay bricks.
Similarly, the mechanical wear and thermal shock experienced by bricks in different parts of the kiln are also different.
All of this requires comprehensive consideration during the selection process to ensure that the selected materials can achieve the expected service life.
3.Key points for evaluating fire brick manufacturers
After determining the type of brick, choosing a reliable refractory brick manufacturer is equally important.
An excellent manufacturer should not only provide products that meet standards, but also have stable production capacity and a strict quality control system.
In addition, the manufacturer’s technical support services are also an important consideration. They should be able to provide professional selection advice and solutions based on your specific working conditions, rather than just selling products.
