Taking heating furnaces in the steel industry as an example, ceramic fiber heating modules are mainly used for ladle covers, billet trucks, and furnace walls of heat treatment furnaces. At present, a large number of ceramic fiber modules are used as linings in heat treatment furnaces that require high furnace cleanliness.
The installation process of the ceramic fiber heating module is simple and convenient, but each step must be strictly in accordance with the requirements of the construction. If the short anchor nails are unstable, it will cause major events such as the collapse of the furnace wall as a whole. For example, installation When the folding target is not staggered, it will cause the four sides of the module to not be evenly pressed and loosen.
The lining structure of the modular furnace uses ceramic fiber heating modules as the lining, and the anchor nails fix the ceramic fiber module on the furnace shell. In this way, the anchor nails do not directly contact the furnace atmosphere, which greatly reduces the heat dissipation of the furnace shell formed by heat conduction. For the rest, in order to protect the ceramic fiber module, a high-temperature-resistant aluminum cloth is sewn on it. This kind of aluminum cloth may be able to withstand high temperature of 1200 ℃, compared with the traditional stainless steel liner, it has the advantages of high temperature fixed shape, easy repair and so on.
From the comparison between the modular lining structure and the traditional structure, it can be seen that the ceramic fiber heating modular lining greatly strengthens the thermal insulation, thermal insulation and sealing effect of the fiber lining. It can be used as a substitute for the complex structure of thermal equipment. The traditional thermal insulation lining structure can effectively strengthen the thermal insulation effect and reduce the heat loss of various thermal equipment.
