Heat treatments in high vacuum furnaces

The heat treatments are sequences of heating, maintenance, cooling at predetermined temperatures, with a predetermined and defined thermal gradient. These processes are used to modify the microstructure of materials such as metals and alloys, to which they confer properties capable of improving their performance.

The use of vacuum technology with shutdown by pressurized gases, combined with the control and management systems of the heat treatment parameters, allows us to respond to the ever increasing demands in terms of quality of materials after heat treatment.

Advantages

  • Overall management of the thermal cycle in all its parameters via PLC.
  • Ability to manage the cooling speed according to the material, the geometry of the pieces and the mechanical characteristics required by intervening on the shutdown pressure and cooling times.
  • Surfaces free from oxidation and decarburization as the treatment is performed in high vacuum (p & lt; 10-5 mbar) and quenching with inert gas (Argon / Nitrogen).
  • Better internal structures.
  • Absence of overheating.
  • Reduction of distortions.
  • Absolute respect for the environment in ecological terms.
