Vacuum Furnace Features
Salient features of vacuum heat treatment furnaces from our joint venture partner Systherms GmbH, Germany
Hot Zone
Thermal Insulation
Inner most layer is of hard board graphite backed by flexible graphite felt.
Heating System
Unique design made from graphite plates all round and along the depth. This covers more surface area (as against tubes/ rod type heaters) and ensures most uniform temperature distribution in the work space.
Convective Heating
System
A separate CC fan mounted on front door for uniform heating under Nitrogen gas up to 2 bar pressure. This ensures better heat transfer during heating in lower temperature range up to 800 degree centigrade. Tempering cycle is also done with convective heating
Quenching
System
Cylindrical cooling with all round nozzles. Front insulation on door is also provided with nozzles which can be opened and closed for convective heating and quenching.
Gas Circulation
High capacity water cooled recirculating fan and cooling motor with VFD and high water flow finned heat exchanger for rapid gas quenching.
ISO Quench
Controlled cooling by monitoring surface and core temperature and varying fan motor speed, gas pressure and switching on/off heating.
Quench Pressure
Up to 15 bar absolute Nitrogen
Host Management
System
Computerised process monitoring and recording of completer cycle and batch reports possible. Remote monitoring and diagnostics from Germany
