Product Details

Lightweight high alumina bricks are also known as high alumina insulating bricks.


Performance & Advantanges:

  • Excellent thermal shock resistance;

  • Low impurity content;

  • High temperature resistance;

  • Good thermal insulation performance.


Applications:

Lightweight high-alumina bricks are widely used in industrial furnaces and thermal equipment, especially in application scenarios where good thermal insulation needs to be maintained at relatively high temperatures. They are mainly used in industries such as steel and glass. It is mainly used as lining materials for heat treatment in various heating furnaces, coking furnaces and other thermal equipment in the steel industry, as well as hot-face lining materials or back-lining insulation materials for various industrial furnaces.
