针对高温常压实验设备中的新型空气加热炉,选择了几种适合用于加热炉保温的保温材料,对其性能进行实验测试,得出保温材料导热系数随温度变化的曲线。通过性能对比,优选出适合高温常压实验要求的保温材料。目前已投入使用,取得了良好的使用效果。 Aiming at the new air heating furnace in high temperature and pressure test equipment, several kinds of heat preservation materials suitable for heat preservation in heating furnace were selected, and their performance was tested experimentally. The curves of the thermal conductivity of insulation material with temperature were obtained. Through the performance comparison, we can choose the suitable insulation material for high temperature and pressure experiment. Has been put into use, and achieved good results.
