High-Alumina Brick Description
The High-Alumina brick has high sintering temperature, high refractoriness under load, high compressive strength, high-temperature flexural strength, and low thermal expansion efficiency.
High Alumina Bricks are produced with selected bauxite chamotte as the main raw material, fired at 1450-1470 °C by the advanced process with strict quality control.
High-Alumina Brick Applications
High-Alumina Firebricks are mainly used in the construction of various industrial furnaces, such as masonry iron-making furnaces, steelmaking furnaces, coke ovens, glass furnaces, cement kilns, steam boilers, various heat treatment furnaces, heating furnaces, etc., as well as other high-temperature furnaces.
Different types of refractory bricks should not be mixed. When firebricks are built, the same type of refractory clay as refractory bricks should be used as cement.
