Fireclay Insulating Refractory Brick for Calcining Furnace
The Description:
Fireclay insulating brick refers to insulating refractory products with 30%~48% Al2O3 content made from fireclay as the main raw material. By using fireclay, bleach bead, fireclay clinker as raw material, adding binder and sawdust, the bulk density of 0.3~1.5g/cm3 products can be prepared through batching, mixing, molding, drying and firing, and the production capacity accounts for more than half of the total output of heat-insulating firebrick
