CCEWOOL high temp ceramic blanket is also known as aluminum silicate fiber blanket. It is a new refractory insulation material.It is white in color and regular in size. It integrates refractory, heat insulation and heat preservation functions, and does not contain any bonding agent. The high temp ceramic blanket is not affected by oil erosion and can be restored to its thermal and physical properties after drying.
(1) Except for the chimney, air duct and furnace bottom, all the other parts of heating furnace can be covered with high temp ceramic blanket or module.
(2) The layered high temp ceramic blanket should be needled blanket at least 25 mm in thickness, and its density should be 128 kg/m3. When the hot surface layer is ceramic fiberboard, its thickness should not be less than 3.8 cm, and its density should be no less than 240 kg/m3. The high temp ceramic blanket for the backing layer should be needled blanket having a bulk density of at least 96 kg/m3. Ceramic fiberboard for hot surface specification: when the hot surface temperature is lower than 1095 ° C, the maximum size is 60 cm × 60 cm; when the hot surface temperature exceeds 1095 ° C, the maximum size is 45 cm × 45 cm.
(3)The working temperature of any layer of ceramic fiber should be at least 280℃ higher than the calculated hot surface temperature. The anchorage of the hot surface layer of the high temperature ceramic blanket shall be 7.6 cm from the edge of the blanket.
Next issue we will continue to introduce high temp ceramic blanket for heating furnace. Please stay tuned.
