Features of high-alumina-refractory-brick

1.High-temperature resistance: The refractory degree reaches 1750-1790℃, and the load-softening temperature is above 1420-1550℃. It is superior to clay bricks but slightly lower than silica bricks.
2.Resistance to erosion: Close to neutral refractory materials, it can resist the erosion of acidic slag. The corrosion resistance increases with the increase of alumina content.
3.Physical stability: High density, high compressive strength, low thermal expansion coefficient. It is convenient for cutting during construction and can meet the requirements of standard or special size dimensions.
