[0002] High temperature bell furnace is a kind of equipment used to heat and process high temperature materials. It is commonly found in industrial production and laboratory environments. High temperature bell furnace can provide a high temperature environment to heat the material to the required temperature. It can be used for various heating and baking processes, such as sintering, drying, calcining, etc.

[0003] Some existing high-temperature bell-type furnaces usually use insulation boards and heat insulation boards for insulation. However, if only insulation boards and heat insulation boards are used for insulation under long-term high-temperature operation, they may be affected by thermal stress and thermal aging, resulting in performance degradation or shortened life. Due to heat radiation and conduction in high-temperature environments, if the insulation boards and heat insulation boards age, high-temperature bell-type furnaces will easily suffer from heat loss. This may lead to reduced heating efficiency and require more energy to maintain high temperatures. Utility Model Content
