Analysis Of Advantages Of Ceramic Fiber Module in Industrial Furnace Lining

Ceramic fiber module as the lining material in industrial furnace has its own advantages, the traditional layer blanket type furnace lining structure is the use of anchoring nails to fix the stainless steel lining plate and thermal insulation foam on the furnace shell, so that the heat in the industrial furnace will be transmitted to the furnace shell with the anchoring nails, and the anchoring nails in the annealing furnace can reach tens of thousands. In this way, the furnace wall is relatively large in heat dissipation, and the ceramic fiber module as the lining of the industrial furnace is to fix the ceramic fiber module with anchoring nails to the furnace shell, and the anchoring nails do not reach direct contact with the atmosphere in the furnace will not cause unnecessary heat loss, in order to effectively protect the ceramic fiber module, Some aluminum cloth that can withstand high temperature is sewn on it, which has the advantages of high temperature resistance without deformation and more convenient repair compared with the traditional stainless steel lining plate. Through the actual investigation, it is found that when the temperature in the furnace of the industrial furnace reaches 800 degrees Celsius, it can be found that the temperature at the welding point of the anchor nails of the blanket furnace presents a peak distribution, while the temperature of the furnace shell is between 60 and 80 degrees Celsius. The temperature distribution of the furnace lining and wall of the ceramic fiber module furnace can be seen. Since there is no long anchoring nail in the temperature diffusion will greatly reduce the degree of heat conduction, so that the temperature of the furnace shell will be reduced as a whole, and the temperature distribution is more uniform, through the test found that the temperature of the furnace shell of the industrial furnace is between 40-50℃. Compared with the structure of the traditional industrial furnace and the ceramic fiber modular lining structure, it can be clearly seen that the thermal insulation effect and sealing effect of the ceramic fiber modularization in the lining of the industrial furnace are more significant, greatly reducing the loss of heat.
