摘　　要：为有效降低回转窑筒体表面散热损失,减少水泥生产标准煤耗,开发新型低导热耐火砖成为研发的重点。本文借助有限元仿真技术,以力学性能和隔热性能为观测点,对新型低导热耐火砖的结构进行优化设计并模拟预测了窑内的使用效果。结果表明,低导热气凝胶材料与传统耐火砖以T型结构复合,既满足耐火砖工程应用力学性能要求,同时可有效降低回转窑表面温度约70℃,具有潜在的应用价值。In order to effectively reduce the surface heat loss of the rotary kiln and the standard coal consumption of cement production,the development of new low thermal conductivity refractory brick has become the focus of research.This paper proposed a portable and low-cost method called“ABAQUS-assisted optimization design”for low thermal conductivity refractory brick composition,which focused the mechanical and thermal properties of the composition,and predicted its application in cement rotary kiln.The results showed that the low thermal conductivity aerogel material was combined with the traditional refractory brick with T-shaped structure,which met the mechanical properties requirements of refractory brick engineering application,and can effectively reduce the surface temperature of rotary kiln about 70℃.The low thermal conductivity refractory brick has potential application value.
