The weight of refractory lining of traditional industrial furnace is large, the heat storage consumption of furnace body is important, the thermal insulation effect is poor, the temperature of cold surface of furnace body exceeds 100 ℃, and the accurate control of furnace temperature is troublesome. In recent years, the refractory lining of furnace wall and roof of industrial furnace has been designed with full fiber lining. Due to the low thermal conductivity, small density and light weight of fiber, lighter steel frame is selected to maintain the structure when designing and building the furnace, so that the development of industrial furnace has entered the era of “kiln lightweight”. The fiber has small heat storage, which is suitable for rapid heating and cooling. Other fiber modules can be processed into special-shaped finished products, which are suitable for various forms of furnace shell inner wall. The fiber module has excellent resistance to mechanical shock and charge, and good chemical stability. These advantages have played an important role in the development of new kilns.
Taking the heating furnace in the iron and steel industry as an example, the ceramic fiber heating module is mainly used for ladle cover, billet carrier, furnace wall of heat treatment furnace, etc. At present, ceramic fiber modules are also widely used as linings in heat treatment furnaces that require high cleanliness in the furnace.
The installation process of ceramic fiber heating module is very convenient, but each step should be constructed in strict accordance with the requirements. If the welding short anchor nail is unstable, it will form major events such as the overall falling of the module and the collapse of the furnace wall. For example, if the folding targets are not staggered during installation, it will form that the four sides of the module cannot be subjected to average pressure, so as to loosen and fall.
The ceramic fiber module is selected as the lining of the modular furnace lining structure, and the short anchor nail fixes the ceramic fiber module on the furnace shell. In this way, the anchor nail does not directly contact with the atmosphere in the furnace, 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 strengthens the thermal insulation, thermal insulation and sealing effect of the fiber furnace lining to a great extent. In the parts with complex thermal equipment structure, replacing the traditional thermal insulation lining structure can effectively strengthen the thermal insulation effect and reduce the heat loss of various thermal equipment.
