Description of Good Price Hot Sale High Alumina Refractory Bricks Alumina Fire Brick For Kiln Furnace

High alumina refractory brick manufactured from Rongsheng Refractory is a kind of alumina-silicate refractory material with content of alumina oxide more than 48%. It is calcined and formed by the raw material of bauxite or the material with high content of AL2O3. High thermal stability, the refractoriness is more than 1770℃. Good slag resistance, used for the liner of masonry steel-making electric stove, glass furnace and cement revolver.

If Al2O3 content of High alumina refractory brick is higher than 90%, it is called corundum brick. Due to different resources, the standards of different countries are not completely consistent. For example, in European countries, the lower limit of Al2O3 content for high alumina refractories is 42%. In China, Al2O3 content in high alumina brick is generally divided into three grades: Grade I – Al2O3 content > 75%; grade II – Al2O3 content is 60-75%; grade III – Al2O3 content is 48-60%.
