Features of Refractory AKZ-85 Alumina Bubble Brick

1.High compressive strength

2.Excellent thermal shock resistance

3.High thermal efficiency of the kiln


Description of Refractory AKZ-85 Alumina Bubble Brick

   alumina bubble brick  refractory brick bricks have high-alumina bauxite powder and refractory clay as raw materials and some inflammable additions, shaped by tamping or extrusion pressing and fired in high-temp tunnel kiln after being dried.

   alumina bubble brick refractory bricks have three brands in accordance with their bulk densities, which are decided by the amount of the inflammable additions.  alumina bubble brick refractory bricks with large bulk density have the features of high mechanical strength and small change of load at a high temperature.
