The
low thermal-conductivity anti-spalling bricks DDR**0, DDR**5
developed by our group are applied in resolving and preheating
zones of cement kilns in lieu of KBL**0 and silicon mullite bricks.
Based on the compound bricks technic and after continual tests and
innovations, the special refractory raw material was artificially
synthesized. The new products based on this raw material have a
lower density, better thermal expansion and thermal shock
stability, better alkali-resistance and lower thermal-conductivity
than anti-spalling alumina bricks KBL**0 or silicon mullite bricks,
more fitting the large-scale development of cement
kilns.
The
kiln diameter, the output, the thermal load of kilns and the
thermal stress on kiln linings increase in the wake of large-scale
development of cement kilns. How to improve the material volume
stability in high temperature is a key factor to ensuring the
material working life. Compared with anti-spalling alumina bricks
KBL**0 and silicon mullite bricks, the low thermal-conductivity
anti-spalling bricks DDR**0, DDR**5 have such advantages as low
thermal-expansion coefficient, stable volume, little material
damage due to the high thermal-stress, low density, low kiln load,
low mechanical-stress on kiln linings, low material cost, low power
consumption, low thermal-conductivity, low temperature of kiln
surface and low thermal-dissipation.
Take the silicon mullite bricks with a density
of 2.*5g/cm3 and the ø4.8×*0m rotary kilns for example. The refractory
can decline by*3.*6 tons per *0m, the kiln load can decline by
*3.*6 tons, and the material cost can decline by *5 thousand RMB in
4,**0RMB/t.
