The fire resistance of ceramic fiber blanket is conceptually different from the maximum service temperature. It can be seen from the Al2O3-SiO2 binary phase diagram that the temperature below the liquid-solid phase line is its fire resistance, which can also be called high-temperature anti melting temperature or high-temperature anti softening temperature. The maximum service temperature is determined by several indexes of refractory fiber, such as fiber shrinkage, fiber crystallization Grain size of fiber, etc.
In refractories, where the content of Al2O3 is greater than 38%, its fire resistance is 1580-1750 ℃. Generally, its maximum service temperature is 300-350 ℃ lower than the fire resistance. The Al2O3 content of refractory fiber is more than 38%, and its fire resistance is about 1750 ℃, but the maximum service temperature is very different from it. Generally speaking, when ceramic fiber blanket and other products are used alone, only the service temperature of the fiber is used instead of fire resistance.
