Ceramic fiber blanket overlay structure, according to the different working temperature of each layer blanket selection of different temperature grades, density, thickness of ceramic fiber blanket, flexible selection of materials, the use of cost-effective; The layered structure makes the fiber direction parallel to the heat transfer direction of the furnace wall, and the furnace lining has good thermal insulation performance, greatly reducing the heat loss.
01 Ceramic fiber blanket overlay structure, should be tested before construction; Construction ceramic fiber blanket on the lower layer should be staggered laying, between the layer and the layer paste firmly.
02 National standard on alumina content of ceramic fiber blanket; 1050 ordinary alumina content is not less than 40%; Standard alumina content is not less than 43%; The content of high purity alumina is not less than 43%; High alumina content is not less than 52%.
03 The thickness of ceramic fiber lining should meet the requirements of insulation design. Measurement method: The length and width are recorded after measurement, and nine measuring points are marked. During measurement, place the disc of the needle thickness gauge horizontally on the sample, align the disc hole with the measurement point, insert the needle tip of the vernier downward, and carefully insert the disc hole. When the needle tip contacts the sample, gently press the vernier, and read the thickness after the needle tip penetrates the sample and touches the glass plate.
04 Ceramic fiber blanket lining is installed, the fiber surface should be smooth and beautiful, extrusion dense. The uneven parts should be flattened by splints; Large gaps are filled with ceramic fiber blanket cotton to ensure good sealing performance of fiber lining.
