What Does The Code T38 Of Alumina Hollow Ball Brick Mean?

Alumina hollow ball brick is a commonly used thermal insulation refractory material. It has low density, light texture, good thermal insulation, and thermal stability, and can effectively resist high temperature, corrosion, and thermal shock. We often see words like t38 on the purchase order of alumina hollow ball bricks during normal procurement. What does the code t38 of alumina hollow ball brick mean?

T38 in alumina hollow ball brick represents the brick number of the brick body and also represents the size of the refractory brick. Its size is 230*114*65/55. The size of refractory bricks varies according to the brick number. Therefore, when purchasing, the brick number is generally used instead of the specific size. You can learn about the specific size of refractory bricks in the article “List of Refractory Brick Size Specifications”, which contains all the brick numbers and sizes of refractory bricks.

Alumina hollow ball bricks are currently widely used in high-temperature insulation layers and flues. They not only have the advantages of good fire resistance and strong wear resistance but also can effectively reduce the weight of equipment and improve the thermal efficiency and service life of equipment. When purchasing alumina hollow ball bricks, we must understand the basic content such as its use location and size, so that we can choose the right refractory bricks.
