Vacuum Furnace
Model： FHH
FHH series are used for various purposes such as quenching, tempering, sintering and brazing of various metals. Chamber configuration can be multiplied up to 3 chambers by adopting fork carry system.
Features
- Maximum temperature1350ºC，Operation temperature800 to 1150ºC
- Temperature uniformity is within ± 5ºC at 1150ºC
- Keeping the heating chamber in vacuum for high quality and repeatability of products.
- Carrier gas system is implemented to minimize metal evaporation.
- At cooling process, heating chamber is not cooled so that power consumption can be saved.
- The heating chamber is kept in vacuum to prevent from oxidizing so that lifetime for internal parts of the heating chamber can be longer.
- Water-cooling jacket construction contributes clean work environment.
Applications
- Quenching, Tempering : Various machine parts, Dies.
- Sintering : Superhard tools, Magnet.
- Brazing : Heat exchanger, machine parts.
