Lightweight high-alumina lightweight brick

Description Refractory heat insulation 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. Refractory heat insulationbricks have three brands in accordance with their bulk densities, which are decided by the amount of the inflammable additions. Refractory heat insulationbricks with large bulk density have the features of high mechanical strength and small change of load at a high temperature. Features ·High compressive strength ·Excellent thermal shock resistance ·Able to lower the heat capacity of the furnace wall ·High thermal efficiency of the kiln ·All types of products available as customers require.
