The high-temperature, high-strength, low-thermal-conduction module has the strength of heavy refractory materials and the heat-insulation effect of lightweight heat-insulating materials. This product is used in rotary kilns with good heat-insulation results, high compressive strength, and low thermal conductivity. High temperature, high strength, and low thermal conductivity modules have great potential for development in rotary kilns in the cement industry.

Application of high-strength high strength, low thermal conductivity module

The temperature of the cold surface of the large-scale rotary kiln in the cement industry is 280-320°C. Since there was no suitable insulation material before, it could not be effectively insulated, resulting in a huge waste of energy. The use of 40-50mm thick high-temperature, high-strength, and low-thermal-conduction modules can reduce the temperature of the cold surface of the kiln body by 100°C-130°C.
