Heat Insulation Blanket 

Heat insulation blanket or high heat insulation blanket is a kind of lightweight refractory material. It is featured with low thermal conductivity, fire proof, and thermal shock resistance, etc. Such high heat insulation blanket is widely used in various of high temperature furnaces and kilns, such as the tunnel kiln, heating furnace, converter, and coke oven, etc.

    Heat Insulation Blanket Composition

    Heat insulation blanket belongs to new thermal insulation, non-toxic, harmless, and contamination-free material, which is made of calcined fireclay, alumina power, and silicon power, etc. All of these raw materials are made into high temperature fluid in the industrial electric furnace, and then they are fabricated into insulation cotton, by the refractory fibers, which are made through the technology of the compressed air injection method or wire rolling method. At last, the insulation cotton are manufactured into insulation materials, such as high heat insulation blanket.

      Heat Insulation Blanket Manufacturing Process

      Heat insulation blanket is made of refractory ceramic fiber, so it is also called ceramic heat insulation blanket or ceramic fiber heat insulation blanket. It is manufactured by special-purpose machinery based on the fiber structure and size. In the manufacturing process, a certain compression ensures the expansion of the ceramic fiber module in different direction after the completion of the lining, which makes the fiber squeeze into a seamless one, ensuring the thermal insulation performance.

      Heat Insulation Blanket Properties

      Heat insulation blankets are high efficient heat insulation materials.

      In terms of construction, heavy refractory materials need baking oven after construction, so they have long construction period, complicated maintenance. Besides, the human and environmental factors directly affect the service life of tunnel kiln. So, compared with such heavy products, ceramic fiber is convenient to use and maintenance, thus greatly save manpower and shorten construction period.
