Product Description
DESCRIPTION
High Alumina Insulation Brick, also known as Light Weight High Alumina Brick, are used in building heat insulating walls or heat preserving walls, which is basically for preserving or insulating heat. Light weight high alumina bricks contain more than 45% alumina oxide. This kind of brick does not directly exposed to high temperature inside kilns or furnaces, it only built closely to the kiln wall as insulation layers. It is a good insulation refractory material, which has a high compressive strength, low thermal conductivity and good insulation quality.
TECHNICAL PROPERTIES
Characteristics:
- Low thermal conductivity.
- Low bulk density.
- High mechanical strength.
Application:
The light weight high alumina insulation brick can be used for the steel making industry.
