Nano - thermal insulation panels are the best choice for devices that require thermal insulation while also requiring small volumes and light weight. For example, for steel ladle, torpedo ladle and tundish in metallurgical industry, nano heat insulation board can be used to replace traditional heat insulation materials in order to realize the expansion increment of these equipments without changing the steel structure. 
The experiment was carried out on 100t steel ladle with nano heat insulation board in Shandong Taishan iron and steel works. the results are as follows: ( 1 ) under the same thickness of heat insulation material, the temperature of outer wall of steel ladle with nano heat insulation board is 105 ℃ lower than that with fibreboard, and the thermal deformation of steel ladle shell is reduced. ( 2 ) under the condition of the same temperature of outer wall of ladle, 10 mm thick nano heat insulation board can replace 30 mm thick fibreboard, ladle can expand capacity and increase efficiency. ( 3 ) after the steel ladle adopts the nano heat insulation board, the cooling of the molten steel is obviously relieved, which is beneficial to the stability of the temperature of the molten steel. And ( 4 ) the nano heat insulation board is more convenient to construct compared with the fiberboard. The nano heat insulation board is packaged by aluminum foil and is waterproof and moisture - proof; And fibreboard in build by laying bricks or stones steel ladle need to do waterproof processing.
