High Alumina Bricks
Product Information
High aluminum bricks refer to alumina content in more than 48% of a neutral refractory material, according to the different aluminum content, mainly divided into three levels: Ⅰ(Al2O3≥75%); Ⅱ(60%≤Al2O3<75%); Ⅲ(48%≤Al2O3<60%). High alumina bricks are formed and calcined from bauxite or other raw materials with high alumina content. They have high thermal stability and a refractoriness of over 1770℃, and have good slag resistance and are used for lining EAF, glass melting furnaces, cement rotary furnaces, etc.
Features
1. Good high temperature performance
2. Good resistance to spalling
3. High thermal stability(refractoriness above 1770℃)
4. Good slag resistance
5. Excellent resistance to acid and alkali corrosion
