Hard felt polyacrylonitrile-based carbon felt or graphite felt as the base material, after special technology bonding, curing, shaping, carbonisation, high temperature treatment. It has good shape retention, self-supporting, small specific gravity, no staple fibre shedding, high surface finish, low thermal conductivity, high temperature resistance, good resistance to thermal vibration (no cracking or deformation in long term use), long service life, easy to install and remove and replace, and the use of the temperature up to 3000°C. It is the best choice for high temperature vacuum equipment, non-oxidative atmosphere, and non-oxidative atmosphere. It is the ideal new type of heat insulation material for high temperature vacuum equipment and non-oxidising atmosphere high temperature equipment.

Graphite Felt Carbonisation Furnace is mainly used for high temperature treatment of carbon/carbon composite materials, rigid insulation felt, curing felt, carbon fibre insulation materials, graphite products, etc. It is also used for graphitization of other materials.

Product Characteristics

- The hard felt polyacrylonitrile-based carbon felt or graphite felt is the base material, which is bonded, cured, shaped, carbonised and high-temperature treated by special techniques. It has good shape retention, self-supporting, small specific gravity, no staple fibre shedding, high surface finish, low thermal conductivity, high temperature resistance, good resistance to thermal vibration (no cracking or deformation in long term use), long service life, easy to install and remove and replace, and the use of the temperature up to 3000°C. It is suitable for high temperature vacuum equipment, non-oxidative atmosphere, and non-oxidative atmosphere. It is the ideal new type of heat insulation material for high temperature vacuum equipment and non-oxidising atmosphere high temperature equipment.
- Suitable for vacuum high-pressure gas quenching furnace, Vacuum Sintering Furnace, pressurised vacuum sintering furnace, monocrystalline silicon furnace, polycrystalline silicon furnace, silicon carbide recrystallisation furnace and other furnace types. It can be processed according to user's requirements, with small processing tolerance, and provide various shapes of products, such as flat plate, disc, cylinder and so on.
- This vacuum carbonisation furnace is a kind of furnace shape specially designed by our company for carbonisation of domestic carbon material insulation material, mainly used for carbonisation and graphitisation of carbon felt hard felt graphite hard felt hard felt drum and firing of all kinds of plates and drum-shaped materials.
