Light weight fire clay brick is made of local top grade fireclay
materials under the high temperature according to the lastest
national standard. The temperature in the 1200-1400 ℃. Ingredients
are mixed with water made of plastic material or mud, mud with
extrusion or pouring shape, 1250-1350after dry burning oxidation
atmosphere. The volume density of commonly used insulated clay
brick is 0.75-1.2 g/cm3. There are insulating clay bricks, high
alumina insulation brick and mullite jm insulating bricks for
insulation layer, which are suitable for different high
temperature. Just please inform us your required bricks working
temperature, we can provide you the most economical suggestions to
you.
Because heat insulating bricks with smaller bulk density whose
strength is not as strong as heavy weight fire bricks, when
delivering, CH Refractories will package insulating firebricks with
special packages to protect insulating clay bricks from damage.
