  • Patent number: 9984794
    Abstract: A thin and lightweight refractory insulating sheet comprising a refractory bag and a layered type thermal insulator in the bag is disclosed. The layered type thermal insulator comprises a thermal energy consumption layer, a reflector and a graphite layer, and can efficiently attenuate thermal energy by conducting the thermal energy in all directions of the plane even when locally heated, and utilizing the thermal energy for vaporization of the water generated from the thermal energy consumption layer.
