Systems for controlled-atmosphere hardening, semi-vacuum hardening, carburising
Components specially designed for use in standard hardening furnaces enable hardening processes under inert gas, semi-vacuum hardening, carburising, etc. These controlled-atmosphere systems are modular in design and can be enlarged to form compact hardening systems. For many of these special heat treatment processes, such hardening systems are a very cost-efficient solution for the user. We can conduct tests and experiments for you in our Test Centre.
Hardening Box System –
Hardening, carburising, nitriding up to 1100 °C- All hardening boxes match the inside dimensions of the annealing furnaces
- The addition of carburising granulate, neutral annealing carbon, nitriding and borating powder ensures the respective surface changes in workpieces.
- Also available with gas connection for almost oxidation-free inert-gas hardening of heavy parts
- Easy handling, reliable processing
Gas Grid System –
Hardening and cooling under inert gas up to approx. 1200 °C- Bright hardening under inert-gas atmosphere with subsequent gas quenching
- Use of ultra-thin foil containers ensures no loss of time during heating
- Can be used with forming gas, nitrogen or inert gases such as argon or helium
- Very low gas consumption due to small container volumes
- Also available with thermocouple for continuous measurement of the temperature inside the container
Inert-gas Hardening System SHA 300 –
Annealing and quenching in oil under inert gas- Annealing in the furnace followed by quenching in oil under inert gas
- Pneumatic lowering of batch into oil bath
- Upward and downward movement for uniform quenching
- Designed for use with KM 50/13 hardening furnace
- System can be moved on rollers
- Also available with gas extractor
