Primarily used for high-temperature treatment of carbon/carbon composites, rigid insulation felt, cured felt, carbon fiber insulation materials, graphite products, and also for graphitization of other materials.

1.Rigid felt, using polyacrylonitrile-based carbon felt or graphite felt as the base material, is produced through special processes of bonding, curing, shaping, carbonization, and high-temperature treatment. It exhibits excellent shape retention, self-supporting capability, low density, no shedding of short fibers, high surface finish, low thermal conductivity, high temperature resistance, good thermal shock resistance (no cracking or deformation during long-term use), long service life, easy installation and replacement, and can withstand temperatures up to 3000°C. It is an ideal new type of thermal insulation material for high-temperature vacuum equipment and high-temperature equipment in non-oxidizing atmospheres.
2. Suitable for various furnace types such as vacuum high-pressure gas quenching furnaces, vacuum sintering furnaces, pressurized vacuum sintering furnaces, monocrystalline silicon furnaces, polycrystalline silicon furnaces, and silicon carbide recrystallization furnaces. Products in various shapes including flat plates, disks, and cylinders can be processed according to user requirements with low machining tolerances.
3. This vacuum carbonization furnace is specifically designed by our company for the carbonization of domestic carbon insulation materials. It is mainly used for the carbonization and graphitization of carbon felt, rigid felt, graphite rigid felt, and rigid felt cylinders, firing various types of flat plates and cylindrical materials.
