Description of High Alumina Anchor Brick

 

High Alumina Anchor Brick is a kind of commonly used refractory material, which is mainly made of Al2O3 and has properties of high refractoriness, high strength, acid and washing erosion resistance, good thermal stability and so on. High Alumina Bricks are widely used in industries of the blast furnace, hot blast stove, electric furnace, refining furnace, and glass furnace and so on. High Alumina Bricks are neutral refractory that can be divided into 4 grades: Grade I means that including 75% contents of Al2O3, Grade II means that including 60~75% contents of Al2O3, Grade III means that including 48~60% contents of Al2O3 and Special Grade High Alumina Bricks include 80% contents of Al2O3.
