High Alumina Brick
High alumina brick refers to refractory products with Al2O3 content higher than 48%.It is made of bauxite or other raw materials of high alumina content .The refractoriness of high alumina brick can be more than 1770℃ . According to the content of Al2O3, high alumina bricks are usually divided into three grades: Grade I─Al2O3 content>75%; Grade II─Al2O3 content is 60～75%; Grade III─Al2O3 content is 48～60%.
Features
- Low creep
- Good slag resistance
- Strong thermal shock stability
- Good erosion resistance
