High Temperature Resistance Good Thermal Shock Resistance High Alumina Insulating Fire Bricks
Introduction:
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.
Features:
High alumina bricks has the feature of has advantages with the lowest and most stable thermal conductivity in various insulating refractory bricks.
Application:
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.
