Descripción del producto

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:
