High Alumina Insulation Brick
High alumina insulation brick refers to AL2O3 content in more than 45% of all light bricks. High alumina insulation brick is made of bauxite and a small amount of clay. After grinding, it is poured into shape by gas or foam in the form of mud. High alumina insulation brick is fired at 1300 ~ 1500℃. Features 1. High temperature resistance; 2. Rapid cooling and rapid heat resistance, excellent thermal shock resistance; 3. Good heat insulation and insulation; 4. Large porosity, small volume density and light weight; 5. convenient construction, can be processed or cut into any size. Application I

3. Good heat insulation and insulation;
4. Large porosity, small volume density and light weight;
5. convenient construction, can be processed or cut into any size.
Application
It is mainly used for high temperature heat insulation layer of kiln, also can be used for lining of flame kiln, but not be eroded directly by slag. It can also be used in kilns with hydrogen, carbon monoxide and other gases as protective atmospheres. The lining material can be made of high aluminum poly light brick as insulating lining.
