中文 High-temperature vacuum sintering furnaces
Type FH I - resistance heated
Description
Due to their induction heating, induction-heated high-temperature vacuum sintering furnaces are used especially for large furnace volumes and application temperatures of up to 2500 °C.
As a result of the uniform energy output, the inductively heated graphite susceptor achieves very good temperature uniformity even at high temperatures of 2500 °C and more.
The higher investment cost compared to resistance heated furnaces is offset by a much longer service life.
Functions
- Working temperature up to 2500°C (even up to 2800°C on special request)
- Vacuum: 5 x 10¯² mbar(a)
- Furnace atmosphere: Ar / N2 / forming gases
- Extended heating zones up to max. 3000 mm
- Debinding and/or dewaxing as a combined process
- Rapid cooling with internal gas circulation (as option)
- Special sizes and functions on request
- Special solutions for C/C and C/SiC composites
- Special solutions for graphite purifiing
