Flexible three -dimensional press mold seal structure of furnace roof

The utility model relates to a thermal power equipment field discloses a flexible three -dimensional press mold seal structure of furnace roof very much. This flexible three -dimensional press mold seal structure of furnace roof includes from nanometer film, ceramic fibre layer and the rhombus nickel chromium manganese steel net of interior outside cover at the furnace roof surface of the work, passes weld in the furnace roof surface of the work stainless steel screw bottom of nanometer film, ceramic fibre layer and rhombus nickel chromium manganese steel net. This flexible three -dimensional press mold seal structure of furnace roof, adopt flexible three -dimensional press mold sealing technique, metal coefficient of expansion after sealed position is heated during the use, adjust by multilayer structure, absorb, whole seal structure is plasticity, can dynamic absorption adjust inflation / shrink variable that the boiler must take place, intactly absorb diversified inflation, leak out because of what hot alt
