The refractory lining of traditional industrial kilns has a large self-weight, the heat storage of the furnace body consumes more energy, and the insulation effect is poor. The temperature of the cold surface of the furnace body exceeds 100 ℃, and the temperature of the furnace is accurately controlled. In recent years, the refractory lining of the furnace wall and roof of the industrial furnace has been selected with full fiber lining. Due to the low thermal conductivity of the fiber, small density, and light weight, the lighter steel frame is used to maintain the structure when designing and building the kiln , So that the development of industrial furnaces has entered the era of “kiln weight reduction”. Fiber heat storage is small, suitable for rapid heating and cooling operation method. The remaining fiber modules can be processed into special-shaped finished products, suitable for various forms of the inner wall of the furnace shell. The fiber module has excellent resistance to mechanical sensation and impact, and chemical stability is also good. These advantages have played an important role in the development of new kilns.
Taking heating furnaces in the iron and steel industry as an example, ceramic fiber heating modules are mainly used in ladle covers, billet handling vehicles, and furnace walls of heat treatment furnaces. At present, ceramic fiber modules are widely used as linings in heat treatment furnaces that require high cleanliness in the furnace.
The installation process of the ceramic fiber heating module is very convenient, but each step must strictly comply with the requirements of the construction. If the welding of short anchor nails is unstable, it will form a major event such as the collapse of the entire furnace wall of the module. Staggered, it will form that the four sides of the module cannot be subjected to average pressure and become loose and scattered.
The lining structure of the modular furnace uses ceramic fiber modules as the lining. The short anchor nails fix the ceramic fiber modules 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.
From the comparison between the modular furnace lining structure and the traditional structure, it can be seen that the ceramic fiber heating modular furnace lining greatly strengthens the heat insulation, heat insulation and sealing effect of the fiber furnace lining. The traditional thermal insulation lining structure can effectively strengthen the thermal insulation effect and reduce the heat loss of various thermal equipment.
