Alumina Silicate Fire Brick for Sale
Aluminum Silicate Brick is a kind of refractory with Al2O3 and SiO2 as main components. According to the content of alumina, it can be divided into silica bricks(15%-30% alumina), clay bricks(30% alumina -48%), high aluminum bricks(alumina content more than 48%). This product is widely used in steel industry, ceramic&glass industry, non-ferrous metals and other industries at high temperatures.
Alumina Silica Fire Brick Applications
1. Steel Furnaces 2. Ceramic & Glass Industry 3. Cement kiln
Three Major Categories of Alumina Silica Bricks
1.Semi Siliceous Products (15%≤Al2O3≤30%) 2.Fire Clay Products (30%≤Al2O3≤48%) 3.High Alumina Products (Al2O3≥48%)
