Low Thermal Conductivity 0.4% CaO Clay Insulating Brick
Definition:
Clay Light Weight Insulating Brick containing Al2O3 30%~46% lightweight refractory products, chamotte
or light clinker and plastic clay as main material, usually can be
the combustible material production and formation of multihollow
structure by chemical method or foam method. The bulk density of
the commonly used lightweight clay brick is 0.75~1.20g/cm3, the
compressive strength is 2.0~5.9Mpa, the thermal conductivity is
0.221~0.442W/m.k (1350°C ).
Lightweight refractory bricks Advantage:
1. Low bulk density, low thermal conductivity, good thermal
insulation performance.
2. Refractory category allow direct contact of fire, suitable for
various atmosphere
3. Good integrity with furnace lining, long service life, easy
operation, could be shaped freely
4. Product specification: standard form, normal standard, shaped
and special shaped bricks.
5. Can be used in various kilns because of its cheapness and
general tray package. Among all of the refractory materials, it is
the most widely used
Application:
Iron&steel making industry:Blast furnace,hot blast furnace(stove),pellet shaft furnace,hot
metal ladle,steel ladle, tundish,heating furnace,soaking pit
furnace,heat treatment furnace,refining furnace,reheating
