Based on the
current refractories for domestic cement production and the
powerful research ability of the Beijing University, Luzhong
Refractory Group developed the heat-insulating and
energy-conserving harrows for the second generation new dry-process
cement production lines.
Harrows are mainly used in preheaters, hoods of kiln outlet and
coolers which have more castables and heat-dissipation. The
heat-dissipation of the parts with castables is mainly caused by
the thermal conduction of castables and harrows. Since outside the
castables are the heat-insulating calcium silicate boards, the
thermal-dissipation is mainly caused by the thermal conduction of
harrows. Since the large number and high thermal-conductivity of
heat-resistant steel harrows led to a high thermal-dissipation, our
group developed the energy-conserving harrows with low
thermal-conductivity after lots of research tests.
The
contrast test data are shown as follows:
| Time | Temperature in electric furnaces | Temperature of castables | Temperature of common harrows | Temperature of energy-conserving harrows |
| Starting temperature | ***0℃ | **7℃ | **0℃ | *7℃ |
| After heat-insulation of 1 hour | ***0℃ | **6℃ | **7℃ | **6℃ |
| After heat-insulation of 2 hours | ***0℃ | **1℃ | **3℃ | **6℃ |
| After heat-insulation of 2.5 hours | ***0℃ | **6℃ | **5℃ | **7℃ |
