High Temperature Resistance Good Thermal Shock Resistance High Alumina Insulating Fire Bricks



high alumina insulation brick . The alumina content of more than 48% , mainly composed of corundum mullite and glass phase or light refractory materials.Bulk density of 0.4 ~ 1.0g/cm3 . The cold crushing strength is 0.78 ~ 3.92MPa.



High alumina bricks has the feature of has advantages with the lowest and most stable thermal conductivity in various insulating refractory bricks.



High alumina brick is widely used in lining and the heat insulation layer of the kiln ,and the part of the erosion of the material without strong high temperature meiting.
