Traditional industry kiln refractory lining has a large dead weight, the furnace body heat storage consumption is important, heat preservation efficiency is poor, the cold surface temperature of the furnace body exceeds 100℃, furnace temperature accurate control trouble. In recent years, the whole fiber lining has been used in the design of the refractory lining on the furnace wall top of the industrial furnace. Due to the low thermal conductivity, small density and light weight of the fiber, lighter steel frame structure has been used in the design and construction of the furnace, so that the development of the industrial furnace has entered the era of “lightweight furnace”. The fiber has small heat storage and is suitable for rapid heating and cooling. The other fiber modules can be processed into special-shaped products, suitable for various forms of inner wall of furnace shell. Fiber module has excellent anti-mechanical shock and charge strength, chemical stability is also good, these advantages for the development of the new kiln has played an important role in the implementation.
Take the heating furnace of iron and steel industry as an example, ceramic fiber heating module is mainly used for ladle cover, billet truck, furnace wall of heat treatment furnace and so on. At present, ceramic fiber modules are used as lining in the heat treatment furnace which requires higher cleanliness.
Ceramic fiber heating module installation is very convenient, but each step must strictly comply with the requirements of construction, if welding short anchor nail is not stable, will form the module as a whole and furnace wall collapse and other major events, such as installation of folding target again not stagger, can form module quadrilateral cannot get average pressure and loose is shattered.
The lining structure of modular furnace adopts ceramic fiber module as the lining, and the ceramic fiber module is fixed on the furnace shell by short anchorage screw. In this way, the anchorage screw does not directly contact with the atmosphere inside the furnace, which greatly reduces the heat dissipation of the furnace shell formed by heat conduction.
From modular lining structure and traditional structure contrast can be seen, ceramic fiber heating modular lining greatly reinforced the fiber insulating lining of the stays, insulation and sealing effect, in thermal technology equipment complex parts, used to replace traditional insulating lining structure, can usefully be improved adiabatic effect, reduce the heat loss of various kinds of thermal equipment.
