摘　　要：耐火砖在回转窑中的主要作用是保护筒体免受高温损坏,同时起隔热作用,减少散热损失,增强回转窑的蓄热能力。过渡带常规配置的硅莫砖导热系数偏大,使筒体温度偏高,散热损失大,长期高温将影响设备正常运转和筒体的寿命。The main function of refractory brickin rotary kilnis to protect the cylinder fromhigh temperature,while isolating from heat to reduce heat loss and enhance the capacity of heat storage of kiln.The general silicon mo brick of the transition zone with larger thermal conductivity makes the higher temperature of the cylinder,and large heat loss,which in long-term will affect the normal operation of equipment and the service life of cylinder.

关 键 词：回转窑 耐火材料 导热系数 热损
