Excellent Performance Alumina Ball Hollow Brick

Alumina ball hollow brick description

Alumina ball hollow brick is a kind of brick widely used in industrial furnaces. Made from a high purity alumina powder, it has a unique construction with a number of interconnected small aerated Spaces. This gives it a number of significant properties, making it a popular choice in a variety of high temperature applications.

Alumina ball hollow brick advantages

One of the most significant characteristics of alumina ball hollow brick is its excellent thermal insulation performance. Its unique structure gives it excellent heat insulation performance, which means that it can effectively prevent heat loss and maintain a stable temperature in the furnace. This not only improves the energy efficiency of the furnace, but also helps to reduce operating costs.

Another advantage of alumina ball hollow brick is its excellent high-temperature resistance. It can withstand temperatures up to 1800 ° C without deformation or cracking. This makes it an ideal choice for applications requiring high temperature stability, such as blast furnaces, hot blast furnaces, and other high-temperature industrial equipment.
