Product Description

LZ-55 High-Alumina Glass Furnace Refractory Fire Brick

Product Picture

Product Features

1. High alumina brick is a kind of neutral refractory material with alumina content over 48%.
2. The raw material of high alumina refractory brick is bauxite or other ore with high alumina content.
3. High alumina brick has high thermal stability and fire resistance above 1700ºC.
4. High alumina bricks have better thermal conductivity than clay bricks.
5. Because Al2O3 in high aluminum products is high and has less miscellaneous mass, softening temperature under load is higher than clay bricks.
6. The thermal shock resistance of high alumina bricks is between clay and silica products.
