A refractory is a material that has stability and corrosion resistance at high temperatures. Among them, corundum brick is the most common high-grade refractory material. Corundum bricks are known for their high hardness, excellent wear resistance and thermal stability. Now let's introduce the characteristics of corundum bricks.
First of all, the hardness of corundum brick is very high, which belongs to the second hardest substance in natural minerals, second only to diamond. This makes corundum bricks have extremely high wear resistance and wear resistance at high temperatures, and can be used for a long time under extreme conditions such as heavy loads, high temperatures, and corrosion.
Secondly, corundum bricks have good thermal stability and can maintain high hardness and stability at high temperatures. They will not suffer from thermal expansion, erosion and other failures due to long-term high temperatures. This can ensure that the corundum brick can be used stably in a high temperature environment for a long time without frequent replacement.
In addition, corundum bricks have very strong corrosion resistance and can be used for a long time in corrosive media such as strong acids and alkalis. They also have good electrical insulation and high temperature resistance.
Finally, corundum bricks also have good processability, can be cut and processed into various shapes according to needs, and are easy to install and use.
In short, corundum bricks have become a leader in refractory materials due to their high hardness, excellent wear resistance, thermal stability, good corrosion resistance and processability. They are currently widely used in metallurgy, construction, machinery and other industries.
