用稳态法研究岩矿棉隔热材料导热系数与密度及温度的关系。结果表明，在一定的工艺条件下，对于化学组成确定的岩矿棉隔热材料，在一个大气压及确定的温度下，在80—100kg/m3的密度范围将出现导热系数最小值：其导热系数随着温度的增加而非线性地增大；并从理论上探讨了提高其热经济性的途径，这为陶瓷窑炉保温结构的热设计提供了科学依据。
Study on the Relationship between Thermal Conductivity, Density and Temperature of Rock Mineral Cotton Insulation Material by Steady. The results show that under a certain technological condition, for the mineral wool insulation material with definite chemical composition, the minimum value of thermal conductivity will appear at the density range of 80-100kg / m3 at one atmospheric pressure and the definite temperature: the thermal conductivity With the increase of the temperature, it increases non-linearly. The way to improve its thermal economy is theoretically discussed, which provides a scientific basis for the thermal design of thermal insulation structure of ceramic kiln.
