Recently, many customers contacted us and asked us about the problems they encountered during the use of aluminum silicate ceramic fiberboard. I hope we can help. Today, I will share with you the knowledge of aluminum silicate ceramic fiberboard. Let’s discuss it together, hoping to bring inspiration and help to our customers and friends, and let everyone have a deep understanding of aluminum silicate ceramic fiberboard.


With the rapid development of the times, the state pays more attention to new energy, and the requirements for energy conservation and consumption reduction in high energy consumption enterprises are becoming higher and higher. In order to achieve the goal of energy saving and consumption reduction in electrolytic aluminum industry, it is necessary to develop new aluminum electrolysis technology with low energy consumption to change the aluminum electrolytic cell from heat dissipation structure to heat preservation structure. Si3N4 combined with SiC material with high thermal conductivity is generally used for the side wall of traditional aluminum reduction cell. At present, it is recognized that the feasible scheme is to lay thermal insulation material outside the side wall material, which not only reduces the heat loss at the side of the cell, but also ensures the stability of heat balance in electrolytic production.
Aluminum silicate ceramic fiber board has the advantages of low heat capacity, low thermal conductivity and good thermal insulation effect. At present, it is used as the thermal insulation material for the thermal insulation layer of energy-saving aluminum electrolytic cell in industrial test. However, in the process of use, it is found that the thermal insulation effect of the electrolytic cell will gradually deteriorate with the extension of service time, resulting in the change of the thermal insulation structure of the electrolytic cell, the reduction of thermal efficiency and the deterioration of working state. In the process of aluminum electrolysis, the cryolite electrolyte in the electrolytic cell volatilizes and decomposes, resulting in a large amount of cryolite vapor, which erodes the thermal insulation materials. Therefore, in order to use thermal insulation materials for aluminum reduction cell, the anti cryolite vapor erosion mechanism of aluminum silicate fiberboard must be improved.
