With the development of suspension preheater and tech breakthrough of decomposition, cement rotary kiln becoming larger and larger. the kiln shell burden obviously heavier than before, kiln runs faster and heavily alkali erosion, all made shorten the lining brick's service life and running period.
Silica mullite Andalusite brick is produced to solve those problem for large rotary kiln as transition zone lining brick. This brick has white corundum which can improve brick's RUL; Andalusite can improve CCS and thermal shock resistance, this brick can replace magnesia spinel brick as magnesia sipnel brick has high thermal conducitivity and low thermal shock resistance.
Compared with spinel brick as below:
Advantages of red silica mullite brick:
1. high temperature resistant, soft with excellent performance. (the actural load softening temperature stability assessment in 168 degrees Celsius above, base on the silicon mo brick high gradespinel which can completely meet the requirement of temp.)
2.anti abrasion, spalling erosion with good intensity.
3. low thermal conductivity, goos heat insulation effect.
4. flexibility, good thermal shock performance
5. density, reducing barrel moderate load.
