Vacuum Furnaces can be mainly divided into the following series:

  • TVCT Series For Hardening and other heat treatments over 800ºC.
  • TVCR Series for Tempering and other Heat Treatments up to 800ºC.

Advantages of Convective Heat Transfer:

  • Shortening of heat treatment cycle time.
  • Possibility of accomplishing tempering at low temperature.
  • Isothermal simulation.
  • Higher cooling velocity.
  • Optimal heat transfer efficiency during heating and quenching processes, due to a well thougth out design of furnace hot zone.

1. VACUUM FURNACES FOR HARDENING:

  • Operating temperature:1350 ºC Max.
  • Heating elements: Graphite resistances.
  • Vacuum level  5 x 10-2 mbar abs. (10-4 mbar as an optional extra by request)
  • Quenching gas pressure: 10 bar abs. Max.
  • Protective gas: Nitrogen (N2)
  • Water cooled double wall construction Furnace chamber.
  • Internal heat insulation and graphite cooling pipes.

HEATING BY FORCED INTERNAL RECIRCULATION.

  • Gas is heated up to approx 750ºC by convective heat transfer process.
  • Forced recirculation gas flow is achieved by means of motor - driven centrifugal impeller mounted on rear side.

COOLING UNDER PRESSURIZED GAS (<10 bar abs.)

  • Gas is cooled by convective heat transfer process while passing through the water - cooled tubular type heat exchanger mounted inside the Furnace front door.
  • Forced recirculation gas flow is achieved by means of a motor -  driven centrifugal impeller mounted on rear side , under operating pressure of 10 bar abs. as maximum , so cooling process time can be shortened.

2.VACUUM FURNACES FOR ANNEALING AND TEMPERING:

  • Operating temperature: 150÷850ºC.
  • Vacuum level: 5 x 10-2 mbar máx.
  • Protective gas: N2, Ar o mixture N2-H2 .
  • Internal muffle ambient air cooling system.
  • Load forced gas cooling system (As an optional extra by request ).
