The excellent characteristics of aluminum silicate ceramic fiber enable the heat treatment furnace that built with aluminum silicate ceramic fiber has a significant energy saving performance.
At present, aluminum silicate ceramic fiber products are more and more widely used in electric heat treatment furnaces, and their two main application scope are as below: cotton wool-like aluminum silicate ceramic fiber bulk is mainly used as fillers for heat treatment furnaces, because refractory fibers have characteristics of both refractory and thermal insulation materials, cotton wool-like aluminum silicate ceramic fiber can replace refractory clay bricks and thermal insulation materials as a single filler for heat treatment furnaces. It has excellent heat resistance and thermal insulation properties, and is light in weight. It is an ideal heat treatment filler. Cotton wool-like aluminum silicate ceramic fiber has many applications in the field of heat treatment. For example, for heat-treated workpieces that are annealed, in order to improve the utilization rate of the heat treatment furnace, the workpiece can be heated and insulated with cotton wool-like aluminum silicate ceramic fiber.
The aluminum silicate ceramic fiber felt is attached to the inner wall of the heat treatment furnace, as a good heat insulation material, its energy saving effect is remarkable. The fiber felt is arranged on the entire inner wall of the furnace and on the tiles of electric heating wire. At present, the placement of the fiber felt usually adopts the inlay method and the stacking method. The fiber felt is inlaid on the brick of electric heating wire, then the electric heating wire compress the ceramic fiber felt tight. And the fiber felt on the furnace top or the furnace bottom are fastened with metal nails. You can use electric heating wire to make metal nails and use cut asbestos board as the backing board on the nail head, and then use metal nails to fix it on the brick seam. The fiber felt should be stacked about 10 mm between them.
Next issue we will continue to introduce application of aluminum silicate ceramic fiber in heat treatment furnace. Please stay tuned!
